Hello all! This is a review of my Pedersoli made Harpers Ferry M1807 .54 caliber "percussion conversion" smoothbore pistol, complete with several clickable links with more information on each subject.

This gun is a new offering from Davide Pedersoli of Italy. It is a rendition of a Harpers Ferry flintlock military "horse pistol" that was converted to a percussion lock system. This conversion was actually done to some of these trusty pistols when that system of ignition came into widespread use during the late 1830s-early 1840s. An original conversion can be viewed here. This style conversion allowed these venerable guns to serve alongside more modern .54 caliber smoothbore military pistols, like the M1842 Aston Johnson guns among others.

Like the later M1842 pistol, these guns were often called "horse pistols" and were used extensively by cavalry, who usually carried two of them that were stored in holsters on either side of the horse's body, offering two quick shots for closer in engagements that were still out of range of a saber.

The Harpers Ferry conversions most likely would have seen use early on during the U.S. Civil War, mainly in the South when more modern arms were difficult to come by. The actual gunsmithing work of replacing the old flintlock mechanisms with percussion locks was carried out by local militia gunsmiths. They were most likely replaced as soon as possible with Colt's or other maker's revolvers for increased firepower as soon as they became available.

This Pedersoli rendition exhibits excellent fit and finish. I should state however, that this is actually the second specimen that I received from Dixie Gun Works. The first pistol I got had some issues with it. Some bubbles in the finish, an off threaded nipple, and off center hammer meant the gun went back to Dixie. They handled the exchange very nicely, and made a point to inspect the second pistol, which had none of these issues. Here it is, with a .530" round ball for scale:

As you can see, the pistol is finished in high-quality American Walnut wood, with brass fixtures, with a notable brass butt cap that was historically used as a club once the pistol was fired. The tapered barrel is made of stainless steel, at least I believe it is, and has a brass front blade sight with no rear sight. The lock plate shows a well done "U.S." crest with "HARPERS FERRY 1807" also printed on it. The gun comes with a ramrod stowed below the barrel, though I chose to use a sturdier one with built in short starter for the purposes of loading.

Disassembly of the pistol is relatively straightforward, though most screws on the gun are very tight, especially the barrel tang screw. Removing said screw as well as the ramrod frees up the barrel from the wood stock. Removing the nipple and percussion drum screw is largely all that is needed to clean the pistol after shooting. The lock can be removed by unscrewing the two screws on the left side of the gun, and is held on by the brass connecting piece there. This is normally not necessary however. I found my normal cleaning method of using a 4:1 mix of water to Ballistol to work nicely on the gun, using some wire brushes and cleaning jags to scrub the bore and exterior surfaces down.

Now, on to the shooting review!

Today I ran about 20 shots total through the pistol. I will say that I had no failures of any kind. I was using Remington #10 caps, .530" cast lead balls from Track of the Wolf, authentic GOEX brand FFG black powder, and .010" lubricated Ox-Yoke .50-.59 patches. All components worked very nicely, and the patched round ball fit nice and snug down the bore, without being excessively tight.

Per Pedersoli's recommendations, I started with 35 grains of powder and held their, bumping up to a 50 grain charge for a "grand finale" shot at the end. :cool:

The gun had a very different recoil to it. It certainly does move in the hand upon firing, but the recoil impulse is more of a "shove" than the sharper feeling of a smokeless gun. I have to say, it's very interesting, and fun! Here is a 1st person video I took of me firing the gun. As you can see, there is some recoil but like I said, it's an enjoyable push. The gun creates a nice cloud of fragrant black powder smoke, as you can imagine. Here is an alternate view of shooting, from the side.

Firing offhand at a paced range of seven yards, the gun was shooting about 5 inches high. Adjusting point of aim to a six o'clock hold dropped the point of impact to the proper level. The gun grouped very acceptably for a smoothbore gun:

hp4.jpg

The first few shots were high and wide, though as you can see by the end of session my groups shrank significantly as I settled down. I am sure this gun can group under 2" at this range, perhaps easily better with a properly tweaked load. I have seen people shoot these smoothbore guns offhand out to 25 yards or so, keeping them within a hand-sized group. Though certainly not as precise as a rifled barrel, a smooth bore isn't much of handicap for this type of pistol. They most likely would have been used when on horseback, fired at relatively close range. For that usage, this accuracy is very acceptable indeed.

I should mention that I was using a wire frame target stand from Wal-Mart, and that it quickly met it's demise against the mighty horse pistol. Said target stands will not survive being shot by a .530" lead ball at speed! A cardboard box was handy and served as a suitable backup target. I will also admit that I was greatly tempted to fire a load while doing a mock "cavalry charge" on my four wheeler, though I decided I better not!

In military service, this gun and those like it would have been most often loaded with paper cartridges, like almost all other service arms of the period. I definitely want to try my hand at making such cartridges at some point in the near future. If anyone reading this knows how to make proper ones, any details would be greatly appreciated.

From my research, it appears that Pedersoli developed this model primarily for use in the N-SSA smoothbore pistol event. Here is a nice write up on said event, it sure seems fun!

All in all, this Pedersoli gun is a fine piece of shooting iron. While not as high firepower as the percussion revolvers that supplanted them in service, these horse pistols served soldiers and explorers alike faithfully during the first half of the 19th century and some years thereafter. If you are in the market for this type of gun, you would do well to get one as I have found mine to be extremely fun and enjoyable to shoot.

Take care all, and have a great Thanksgiving!! :D

I have heard reports that the wooden ramrod tends to swell and get stuck in its channel. Did you notice anything like this?

Originals are found with both wooden and steel ramrods. Pedersoli should have supplied a steel ramrod.

Very handsome looking pistol with clean lines as well as being nicely assembled and finished. Good to hear Dixie Gun Works made things right with the exchange on the second gun.

Thanks! I am going to experiment with buck and ball, straight buckshot, and maybe even birdshot loads in the near future. I love this gun!! :D
 
While doing a search on the M 1842 pistol I cam across a site by a firearms rental place (for movies and such) in Britain called Foxtrot.

They had one picture of an 1842 replica and no other information about the replica. All the metal work was black, including the band and but cap and the wood looked cheap.

Search as I could I could find no other reference to an 1842 pistol replica.

I did note that 1836 flintlocks had more than one type of percussion conversion applied to them in the photos of them.

While there were photos of the Harper's Ferry pistols converted as well there were none that featured a clean out screw on the drum.

Still the OP's gun looks neat as all get out.

My search naturally turned up a few of the other 1842 pistol , the Navy model that had its hammer behind the lock plate to present a flat side to the world.....now there is an ugly little devil I don't see folks rushing out to buy replicas of!

KBob,

Yes, the clean-out screw is something of a more modern touch. I personally appreciate it! Make cleaning the drum a snap with some pipe cleaners and moose milk.

I have been in contact with one of the head N-SSA weapons approvers and he assured me that this Pedersoli model is faithful in overall design, and these converted pistols could be and were found in the arsenals of local Southern militias at the outbreak of the Civil War, and no doubt were probably used at least to some extent very early on in said conflict. Being as this model is N-SSA approved, it has to meet a number of requirements for authenticity and historical accuracy. It was actually a joint effort between the N-SSA and Pedersoli to create an appropriate replica for use in the relatively new Smoothbore Pistol event. Before this one, there were no replicas out there for this event and all shooters were using original pistols. Trust me, I did my research before buying this gun. ;)

For many years I had a copy of the 1805 Pistol in flint. (Mine was an early copy and cut for the 58 caliber common to the makers of the day.) I enjoyed it quite a bit but preferred my 1803 HF Rifle and let it go.

I also had a copy of the 1855 HF pistol complete with the shoulder stock. Again, I preferred a full sized longarm and it to went to a re-enactor.

Your pistol is a good looking firearm, and you have made nice photos with it. I hope it serves you well.

Thanks Kevin! I sure do like it.
 
Question: Does the whole percussion drum unscrew from the barrel? The reason I ask is that I'm still considering using this gun as the basis for a reconversion back to flint. I know that Pedersoli makes screw-in touch hole liners for some of their flint guns. If the percussion drum is removable, and the thread is the same, that would make that part of the reconversion very feasible.

Pedersoli is missing a good opportunity if it does not bring this gun out in the original flint. (Their current offering, in .58 cal., leaves a lot to be desired.) They could even offer a set with interchangeable locks, so the user could switch back and forth from flint to percussion.

That's a smart idea, AlexanderA.

I am not sure if the entire drum screws out. I haven't tried it, but it seems to be snug if it does come out. While Pedersoli's .58 caliber rifled flintlock version isn't so historically accurate, this .54 smoothbore version with proper "in the white" finishing is most correct.

What I've found is Pedersoli likes to hear from customers. Perhaps you could message them? I am sure they will respond.
 
I suppose I can understand re-engineering an existing design for a later period re-enactor. I wish someone would come out and make a real 1840's Waters or Palmetto pistol replica. As far as US style Horse pistol repros, we jump right from the Harper's Ferry to the 1855 Pistol carbine repros annd skip everything in between.
 
Agreed. Not many repro horse pistols to choose from. I would love to see a repro 1842 Aston Johnson myself, but in the meantime this fine Pedersoli will do. :)
 
Just got done shooting this pistol again guys:

I am totally thrilled with this gun. It is shooting like a dream! :D
 
Great shooting! Was that from a bench or off hand? What distance, and do you mind sharing your load info?

Thanks!
 
Just A Curiousity...

I know your pistol is a single shot of .54 caliber (very impressed!)...

I just wonder if Sam Colt would have had the idea of using a Walker or Dragoon as a platform for a .50 cal revolver with a 4 shot cylinder.

Would that have been plausible, just considering that the OP's .54 single shot pistol would have been a bit of overkill while hitting a single soldier/combatant and no reload or extra shots, or would a .50 cal revolver be overkill?

In the modern world we have, at a minimum, the .44 Mag, the .454 Casull, the .460 Rowland, and the .500 S&W, among others.

I am just floating ideas for plausible speculation.

Jim
 
The "funny" thing is, until the 357 mag came into being the Colt Walker, with the standard load, was the most powerful revolver. I'd guess that a four shot 50 cal. vs a 6 shot 44cal wasn't considered.
Look how quickly the 5 shot Patterson was considered obsolete.

This was standing offhand, with one-hand grip, at approx. 10 yards.

35 grains of GOEX FFG, a .530" cast lead ball, and Ox-Yoke brand pre-lubricated .010" patches. :)

I am super pleased with how accurate this gun is, especially considering it's not rifled and has no rear sight!
 
Beautiful pistol and shooting. Those can be a challenge to shoot well but you sound like a muzzle loader kind of guy.
 
Were the locks on the original 1805's in the white like the barrels or have the examples that exist today simply lost all their color?

I recently picked up a mint flint Pedersoli replica for almost $200 less than retail and while I have no big issue with it being a rifled .58 caliber, I would like the appearance of the pistol to be accurate. I can only assume that Pedersoli produced these pistols in an incorrect oversized rifled caliber to prevent faking, but I cannot fathom why they used a color case process on the lockwork if the originals didn't have it.

I have read that most color case hardening done by the Italian manufacturers is mainly for looks and is not very deep. I've also read where some have removed the color with nothing more abrasive than Semichrome, Flitz, or MAAS metal polish.

Any thoughts?

BTW, here's a shot of mine. It came unfired in the original Pedersoli box. The date code indicates it was manufactured in 2005, which would explain the sealed promotional VHS tape that was in the box.

From my conversation with one of the head N-SSA weapons inspectors and additional research, these pistols were in fact produced in the white, and the color case hardening is not authentic to the original design.

Thanks, and great review by the way on your percussion conversion model.

The only thing I have to decide now is if trying to polish the lock work to remove the color will achieve the right look or totally screw it up.

Obviously, I will leave the face of the frizzen alone since it sparks quite well now.

Cheers
 
I'd leave it be, and just buy this pistol instead. :D! LOL!

Really though, I'm not sure how it would end up looking. You risk ruining it IMHO. It's your gun, but even thought it's not historically accurate, it still looks good.

Some out there think Pedersoli might release a proper Harpers Ferry without conversion, i.e. flintlock .54 smoothbore with in the white finish, though that's just a rumor. I've found Pedersoli to be very interested in customer suggestions. You could always contact them asking about it if you are so inclined.

Well, I've always been a risk taker, so I decided to give it a shot and started not long after my last post. It turned out to be no trouble at all to remove the case colors. In fact, I spent more time disassembling and re-assembling the lock than removing the color. I also had to spend some time searching through my old tools for my spring vise. I haven't fooled with a flintlock in a very long time. Amazingly, I didn't have any parts left over when I got it back together.:D

I first soaked the externals in vinegar, but left the springs, tumbler, and stirrup alone. The vinegar didn't seem to do much to the color case parts, but it did lighten up the hammer screw which was blued.

I used semi-chrome polish and the case colors came right off with very little effort.

I'm quite pleased the results:

That looks great!! Glad it worked for you.

If you wanted to go "all the way", I'm sure you could get someone to sleeve the barrel for you to make it a smoothbore .54 caliber. That would be the bees knees, how does it shoot with the .58 rifled barrel?
