Hello. Several weeks ago, I opted to build a long slide .45 ACP under the watchful eye of a close friend who had made a very fine 1911 via Dave Sample's On-Line 1911 class. I'd been most impressed with his pistol and that of his son, who'd also taken the course. I had seen and shot both of these pistols and had to have something similar.

I have fallen in "love" with long slide 1911 pistols since I tried an STI Trojan 9mm with a 6" barrel.

The Gun:

The frame and slide are from Caspian. I chose the cast frame as it cost less and I've had stellar results with a Colt/Caspian 5" gun that my gunsmith, Lou Williamson, did for me in the '80's.

I used Kart's EZ-Fit barrel. "EZ" is a relative term, but I can darned sure see how it would be easier than a "regular" oversized match barrel.

For my purposes, the range and for some hunting, I opted for the Bomar rear cut and the Novak front sight cut. Purely for looks, I went with the serrated flat on top of the slide. The frame was supplied with 20 LPI checkering per my request.

The flat mainspring housing from Ed Brown was also checkered 20 LPI. The hammer and sear are from Ed Brown as well. I flat don't remember who made the safety I wound up using as I'd owned it for quite a while. The trigger and disconnector are from McCormick. The 2-piece guide rod is from Brown and the stainless pins were from Caspian. The gun has a standard power mainspring and the recoil spring is 17-lb. The grip safety is an Ed Brown with hump and "memory grooves." The pins, hammer, slide stop, and thumb safety are stainless that I polished (for hours).

From the initial file stroke, through fitting the slide to the frame, and on to the finish was around 70+ hours. (I would starve to death as a gunsmith.)

Before the gun had a blue finish or even the sights applied, I test fired it. There were no stutters in firing or any malfunctions of any kind. However, it would not feed a Corbon 200-gr. JHP +P from a full 8-round magazine by hand. Downloaded by one, it would, but not off a full magazine. I experienced precisely the same thing today when trying to chamber a Speer 230-gr. Gold Dot from a full 8-rnd magazine. The same load fed fine from both a Novak and Colt 7-rnd magazine.

Here's a view of the gun after it was blued. It has polished slide flats as well as on the top of the grip safety (on the "hammer side") and the area inside and outside the triggerguard. This took several hours by hand. The only place a dremel was used was to clean up the inside of the dust cover. The bushing was bright polished by hand as well.

This is the polished area around and on the trigger guard.

The complete gun...

Ammunition:

"Sweet Pea" has been used with several types of ammunition:

Handloads: 200-gr. Precision CSWC over 5.0-gr. Bullseye

200-gr. Hornady XTP over 7.2-gr. Unique

Factory Loads:

Sellier & Bellot 230-gr. FMJ
Winchester USA 230-gr. FMJ
Remington 185-gr. MC Flat Point
Corbon 200-gr. JHP +P
Winchester 230-gr. "Subsonic Deep Penetrator" JHP
Winchester 230-gr. Black Talon 230-gr. JHP
Winchester 230-gr. Ranger SXT JHP
Remington 230-gr. Golden Saber
Speer 230-gr. Gold Dot
Glaser 135-gr. Silver +P
Federal 230-gr. Hydrashok
Federal 230-gr. Classic JHP
Federal 185-gr. JHP

All total, approximately 600 rounds have now been fired through the gun.
There have been no failures to feed, extract, or eject. Cases are not dented during the ejection process.

I also used several different magazines today:

Colt 7-rnd
Novak 7-rnd
MecGar 7-rnd
Wilson 8-rnd
McCormick Powermag

All locked the slide open on the last shot. With all but the Gold Dot and the Corbon (using the old Speer "flying ashtray" JHP), they fed fine by hand when fully loaded.

It seemed that the Colt 7-rnd ran the smoothest followed by the McCormick. With ball, Golden Sabers, Federal 230's, and the SWC's I couldn't tell any difference in smooth operation.


Shooting:

This pistol is intended for accurate shooting. Therefore, it was fired in slow-fire only. Distances were 15, 25, and 50 yards. All groups were fired from a rest and in a seated position. The reason for this is to try and wring out all the pistol has to offer. I am sure that I didn't do that, but it was the best effort I could perform.

15 Yards:

Each group consists of 5-shots and was fired from a rest.[/img]

25 Yards:

The magazines used along with the handloaded 200-gr. Precision CSWC in firing this group. The flyers are my fault.

50 Yards:

This was done with Winchester USA 230-gr. FMJ.

Observations:

Once again I have not seen evidence of the slide functioning slowly. Some have reported this when firing such versions of the 1911. This one operates fast as a 5" as far as my eye can tell and so does the STI 9mm.

Felt recoil is the same for me as with a 5" gun. I'd expected this to be a bit less due to the extra weight out at the end of the gun. Chronograph results show that the extra inch of barrel give roughly 50 ft/sec extra. Felt recoil is subjective to be sure but to me, I note no difference in recoil. There may be slightly less muzzle flip. In any event, it's not a problem.

This one's a keeper. Not only because of sentimental reasons and simply being proud of my first effort, but because it works; at least so far it does.

I intend to use it for the range and for hunting as mentioned above. Right now, I'll sight it in for the 200-gr. CSWC. For hunting, the rear sight will need to get about 2 clicks to the left. On this pistol I'm glad to have adjustable sights which have held true zero when set.

It is said that there can be but small difference between a hobby and an obsession. I now understand.

While I'm very pleased with this pistol and the way it performs, it is not perfect.

Maybe I can make the "perfect gun" next time....NOT! I don't think it exists.

This achievement most certainly does NOT make me a gunsmith in any sense of the word. It DOES make me appreciate and "see" more when I look at a 1911 that's been worked over.

Best.
 
From the initial file stroke, through fitting the slide to the frame, and on to the finish was around 70+ hours. (I would starve to death as a gunsmith.)

There is a reason that gunsmiths do not occupy the slots of the top 500 wealthiest people in America! To do it right is labor intensive. Looks like you did it right. Happy shooting!
 
Very nice job! Beautiful piece with wonderful polishing on the slide! I am proud of you like my own son! :D

So you think an untrained monkey like me with forum friends like all of you could do it too? I sure would like to... after the AR was so easy and I felt so good about it, it is hard to imagine something more difficult and how it would make me feel. I figure as long as I don't try to do my own checkering, I should be okay! :cool:
 
Hello. You are exactly right. I have ordered from both companies in the past and just don't remember which I got that safety from.

Best.
 
Mr Camp,

Your feeding problem is due to the combination of the shorter ogive of the Speer 200gr Flying Ashtray exacerbated by the angular gap that occurs in all magazines but moreso in eight round models.

If you load two rounds in a 1911 magazine you'll notice the rounds lay smoothly on each other touching on both rim and mouth. As you add rounds you'll notice the mouths of the top two rounds will start to have a gap between them. By the time you get to six this will be quite noticable and will increase exponentially from there. Meaning that the gap between 6 & 7 will be greater than the gap between 5 & 6. The gap is greatest between 7 & 8. Since the top cartridge has it's hold angle determined by the magazines feed lips that means that as you progress lower in the magazine the cartridge noses become lower in relation to their bases.

Take a fully loaded magazine and you'll notice that you can more easily push the nose down than you can the base.
That means the top round in an eight round magazine, due to the increased angular gap will "nose dive" lower when the slide tries to strip it from the magazine.
The shorter OAL and nose profile of the old Speer bullet means that the nose will strike lower on the feed ramp. Just a tad bit too low to allow it to feed in this case. A bullet with a longer OAL and a better nose profile may not strike so low as to bind.

I'd wager if you loaded 7 Speer/Cor-Bon and topped the mag off with a single round of hardball that all 8 rounds would feed and fire just fine.

In the early to mid 1980s I carried, off dity, an early 1970s Colt Lightweight Commander that wouldn't feed a Flying Ashtray from the top 2 in a 7 round mag. But was 100% from 3 down.
I'd load the chamber with a Speer and the magazines I'd load with 4 Speer topped off with 3 Remington 185gr JHP. The Remingtons didn't expand as well but they fed 100% from the top.
 
Hello. Thank you, sir. I've noted the same sort of thing over the years. I've always considered those sort of a "worst case" feeding cartridge.

Best.
 
BluesBear - I am experiencing top round nosedive in my Dan Wesson Pointman Major 1911 with both the factory mag and with * round Novak mags, with Federal Hydroshock 200 grn bullets. Do you think the cause is the same, and will additional polishing of the feedramp make a difference? Thanks in advance -
Rich
 
I am familiar with the standard Federal 230gr Hyrda-Shok, the reduced recoil 165 gr Hydra-Shok and the LE +P 185 gr Hyrda-Shok. I have never seen any 200gr Hyrda-Shok so I can't comment on the bullet ogive or cartridge profile.


As a rule I always advise against polishing a feed ramp sight unseen unless there is a obvious imperfection affecting feeding all ammunition.
While feedramp polishing can be beneficial in many instances it is quite often eother overdone or it simply masks another problem which still hasn't been addressed.

A few things that also need to be known...

If you load the troublesome ammo as the last round only on top of a mag full of hardball does it still jam?

If you load a single round of ball on top of a mag of the troublesome ammo what happens?

Will the troublesome ammo feed from top of the mag if cycled slowly by hand?

Will the troublesome ammo feed from middle of the mag if cycled slowly by hand?

Does it jam from top of mag when the slide is released from slide lock?

Does it jam from top of fully loaded mag when a chambered round is fired?


All of these things can help track down the real culprit.

But before anything should be done you need to determine if it's an ammo problem a magazine problem or a gun problem.
 
UPDATE: The pistol is back at the gunsmith for the second go-round.
1st visit:
replaced sear, fitted to existing hammer
throat barrel
polish feed ramp
radius barrel and slide locking lug edges
lighter mainspring.
recommendation to use Chip McCormick Power Mags

Went to range with new mags - multiple jams, especially with plated bullets. noticed extractor clocking, gun tied up once with what I beleive to be dropped firing pin stop - back to smith.

Now the gun is gettting
Oversize Ed Brown stainless steel barrel bushing
Ed Brown "Hard Core" bar stock extractor
EGW oversize firing pin stop being had-fitted
Top coil of mag springs rebent.

Smith says that the problem is tolerance stack-up in the manufacturing of the frame - combination of an over-size mag well and a low mag catch is causing the nosedive - he says it should work OK when I get it back (I know the bushing had nothing to do with the feeding problem, but I think the stop and extractor may have - old extractor could be bent by hand, wasn't holding tension). So far I'm not real impressed with the DW - there is no excuse for the loose bushing, the crappy sear, and the junk extractor, much less the machining errors....
 
Mr. Camp:
That is a beautiful pistol, and once again, a terrific range report.

ps where can I send the check for the Stephen Camp Caspian Custom sn #00002 ;)
 
Hello and thank you. Actually "02" is under construction right now. It will be like "01" except that it's a conventional 5" length.

Best.
 
Hello. That could happen, but it will be a while. Worked on the frame yesterday from about 1PM til about 9PM using only fine grades of sandpaper. My fingers are so danged sore this morning that I couldn't hold a powderpuff!

Best.
 
I'm in the same boat with sore fingers. I have spent the majority of the past two days either sanding and finishing a 1903 Springfield stock or removing the casting flashing and polishing the lock and brass parts for a flintlock rifle I am building. While I have a couple of 1911 projects ongoing, they are both in a position where I need to put them into the hands of a gunsmith/machinist to finish up.

Funny, everytime your 6" 1911 post comes to the surface, I have to make a trip to the Caspian website....

BTW, why haven't you added this article to your website? It would save me a lot of time whenever I want to drool over your photos! :D :D
