I originally posted about this pistol in this thread. See there for more pics.

At the beginning of September 2007 I purchased an HK USP Compact Tactical with a Gemtech Blackside suppressor. Last week (December 5th) my Form 4 came back and I picked up the suppressor. The total cost with the tax stamp was just under $2,000.

Initial impressions (look and feel)
The softside case is sexy I must say. There is a place for the pistol, pouches for two mags, a sleeve for the suppressor, and another pouch that I'm not sure what it's for. It seems handcuffs would fit in it, so maybe that's it. The interior is Velcro allowing you to move all of the items around to your liking. When I picked up the suppressor, one of the first things I did was reorganize the case. ;) Overall, it's pretty cool I think.

The pistol feels pretty good in my hand. It's certainly no P220, but the size and shape is reasonably comfortable.

The suppressor goes on easy enough, but until I got used to it I routinely tried to screw the suppressor on "backwards". That is to say, the threads are reverse so attaching the suppressor in a way that feels natural doesn't work. After attaching and removing it enough times I began to get it right without thinking about it.

The suppressor isn't overly heavy. In fact, it's pretty light. A buddy of mine picked it up and his first reaction was, "Wow. I thought this would be heavier." Anyway, as the suppressor is relatively light, it does not make the pistol feel inordinately front heavy. Aiming and shooting feel fairly comfortable.

The sights on this pistol are standard 3-dot white. They aren't high-rise sights and so don't rise above the suppressor. Before I had fired this pistol I felt that they were close enough to the top edge of the suppressor get reasonably accurate results.

This idea of "close enough" fell apart rather quickly once I fired the pistol. More on that momentarily.

Non-suppressed performance
Firing this pistol without the suppressor attached was a joy. It is accurate, feels good, and there were no malfunctions through 300 rounds. I can easily say that I am very pleased with the non-suppressed performance. Below is a target I shot at 15 yards (45 feet). 8 rounds, about 1 round per second, standing in a modified Weaver stance.

Suppressed performance
The suppressed performance of the pistol was rather lack-luster. There were numerous feel problems and the accuracy was not what I'd have liked. Stove-pipe jams occurred about once per 10 to 12 rounds on average, although I was able to zip through a full 8 round mag in rapid fire without an issue twice. Below is a picture of a common jam I experienced.

Rounds that did successfully eject occasionally hit my nose or forehead. Quite a few times the spent case ejected and came to rest on my firing hand (right hand) or wrist, causing me to flinch to get the hot case off me.

Last round hold open was just about non-existent. I regularly found myself pulling the trigger on an empty chamber if I had not counted or had miscounted rounds fired. I found that I could get the slide to hold open if I jerked my wrist just right as the pistol was fired, but this was still unreliable and affected what accuracy there was.

Accuracy was not good. I am unable to determine whether or not this is due to the lack of a full sight picture because of the suppressor, or some other reason. Shots at 15 yards were consistently low and to the right by about 8 to 10 inches.

There was no evidence of bullet strikes on or in the suppressor. I did find that I could somewhat compensate for the low-right hits and get rounds in the 9 ring, but it was inconsistent and eventually became frustrating.

I fired about 200 rounds through the pistol with the suppressor attached. After about 60 rounds I could actually see the heat coming off the suppressor as I aimed. This further affected the sight picture as the heat distorted the target. When tightening the suppressor I found that I had to use my shirt to cover my hand, and even then it burned pretty good. Also, as the suppressor got hotter there was more and more smoke. A couple of times I was able to blow solid smoke rings by puffing directly into the open chamber. I had the thing billowing smoke at one point.

Suppression/noise reduction
Like many people I occasionally called a suppressor a "silencer". Even before using one I understood that the report of the firearm was not "silenced" and would still be audible. I even knew that Hollywood had it wrong and that the report would be louder than often depicted. I've seen YouTube videos of suppressed firearms and based on what I could glean from those videos the term "silencer" still seemed reasonable. This was all about to change.

After we finished up at the range, my buddy and I drove a good long ways out into the middle of nowhere to find out what suppression was all about. In this experiment the suppressor was fired dry. I attached the suppressor, loaded a mag, chambered, aimed, and pulled the trigger. First words from my mouth... "J***S CH**ST!!"

I can now report to you all that the term "silencer" is a complete and total misnomer, and that I will never call it that again. There was nothing that could ever be considered "silent" about this experiment. The muzzle report is reduced by a GREAT deal, and no hearing protection is needed. But in order to understand what "reduced by a great deal" means, you really have to know what a .45 sounds like normally. Your ears will ring and it will be painful. Not a pleasant experience at all. This is not the case when suppressed. I pulled the trigger several times without concern for my hearing. It didn't hurt, and my ears didn't even come close to ringing. But I can tell you that it was not quiet at all.

The best approximation I can make is with a standard rubber party balloon. Blow it up to its absolute limit, tie it off, hold it about a foot from your face, and pop it. That's what a suppressed handgun sounds like. If you were to fire it in a moderately crowded parking lot or in a park with others around (as is often depicted in movies), people will notice even from several hundred yards away and will likely call the cops (as is never depicted in movies).

In a closed room such as an apartment or a hotel room, suppression is enough that most people in adjacent rooms would likely mind their own business. As well, shots fired indoors would likely not be recognized as "shots" from outside. In this regard, suppression is adequate.

Summary
Am I still happy with it? Yeah. I don't regret buying it. It's totally sexy and cool as hell. The non-suppressed performance was awesome, and even suppressed it would be reasonably accurate inside of 10 feet.

I was disappointed by the feed problems, but I guess I'm not all that surprised. Put what is essentially a weight on the end of the barrel and these things will happen. I feel like if I used hotter loads (like +P or +P+) it would be pretty reliable. Or maybe even if I got a lighter weight recoil spring. I looked at each jam closely and it appeared as if the slide was not coming back hard/far enough during recoil. This was evidenced by the weak ejection of spent casings. They often hit my wrist, arm, and grazed my face from time to time.

I also found that as the pistol got dirtier it jammed more frequently. This jives with the above in that if the slide is not moving rearward hard enough, it will only get worse as it gets dirtier and, effectively, less lubricated. For what it's worth, the pistol has never been cleaned. This range session was done with the pistol "right off the rack" and "straight out of the box". I plan to give it a thorough cleaning and try it out again next weekend. We'll see how that goes.

The suppression wasn't what I expected at all. There is however no doubt in my mind that the muzzle report was reduced considerably. I have had the "pleasure" of firing a Colt Commander without hearing protection. Not fun at all. It hurt and my ears were ringing for hours. This pistol is roughly similar to a Commander in size. Firing suppressed without hearing protection was no problem at all. But as I said, it startled me as to how loud it still was. I want to try firing it wet one of these days to see if that helps. I'm told Vaseline works well so I'll probably use that. I may also try water and regular oil. I'll be sure to post with results if I ever do this.

So there's that kiddies. Hope you enjoyed it! I know I did. :)

Ive shot a suppressed surgon bolt action rifle in .308 and the thing was less loud than a .22lr. With the feed problems and the accuracy going down and to the right like that im thinking that the barrel is having problems with the added weight of the suppresor. I know that you said that it was already a pretty light suppresor but maybe you should look into a different brand.
 
Fantastic report. Thorough and informative. I really enjoyed reading it. Thanks for the description of what a supressed pistol sounds like. I've also had the "pleasure" of hearing a .45 go off without hearing protection. The ringing lasted for hours.

The pistol and case have a very high cool factor. I know you're a bit disappointed, but looking at your pictures, I don't think that the accuracy fell off by much. POI changed, sure. But that could be caused by the partially obstructed sight picture, "seeing" or turbulence caused by rising heat, and even unfamiliarity with the new feel - as you have observed. Give it a couple more outings.

As for your malfs? It'll be interesting to see if spring changes or different loads help. I'll bet someone will be able to offer some first hand knowledge on the subject.

Thanks for the post. Keep us informed with any updates.
 
The sights are easily fixed:

The front sight can't be put on my the Hk sight pusher it needs a taller pusher, or to be hammered on.

The stove piping might be fixed by breaking the pistol in more. My USP Tactical (full size) had 4,000 rounds through it before I put my suppressor on it (slow delivery by Gemtech). You can either try to break it in, or bug Gemtech for a Nelson device which will fix most of the issues.

The POI change is normal, but not as major, mine is 1-2 inches up and to the right unsuppressed when zeroed for suppressed Speer Gold Dot 230 JHP. So are the heat waves.

The sound can be made quieter by adding a sacrificial medium like water or gel (like Ideal Clear Glide Wire Pulling Gel). But yes the Blackside is on the loud side compared to other 45 cans. 22LR and 9mm quiet a lot easier.

My personal opinion about the Blackside for someone that doesn't own one, spend the extra $200-300 and buy one of the following cans: CCF Carbon Fiber Can, SWR HEMS 2, AAC Evo 45, or the KAC Mk23.

For someone that owns one, and has cycle issues, bug Gemtech and you might get a Nelson Device if you are annoying enough. There is no reason you should have to replace your springs to cycle a piston can, in this day or age.

Anyways my Blackside USP combo.

What kind of case is that? It looks really nice!

Thanks! It comes as part of the USP (Compact) Tactical. You can also get one by itself I'm told for about $40. Google for it and you should find one.

On suppression
I plan to try firing it wet one of these days here soon. I'll try different medium and see what works best.

Some further reading tells me that my experience is normal for a dry suppressor of any brand. Apparently the trick isn't taking away sound necessarily, but to make the shot sound like something else less menacing (like a car door slamming).

I'll see what happens when fired wet and post back here.

On feed problems
I still have to clean and lube the pistol. As I said, it was "right out of the box" and pretty dry. I'll clean and lube and see how that goes. I'll also experiment with different loads and see what happens.

As PPGMD points out, it may also be a break-in issue. So I will see how things go over many rounds.

Can .45Colt bullets be loaded and fired in .45ACP pistols (and brass)? If you bumped bullet mass up to +-250gr would that have dual effects of increasing recoil force for the slide and also maybe slowing gas velocity?
 
WOW I want one! *drools* I just dont want to go through all that trouble to get a tax stamp. I dont know the LEOs here where I live so I doubt they would let me get a suppressor.

Very nice pistol though. Congrats!

:)

Go the trust route and you don't have to ask for local permission.
 
Nice writeup.

You should ALWAYS clean a new gun before firing it for the first time. HK, in particular, uses packing grease on their guns. Some have more of this than others. But, that's why its always a good idea...
 
I've fired suppressed airguns (where built in suppressors are legal) and a huge part of the noise difference from one to another is the action. PCP (precharged pneumatics) airguns, which don't have much more than a valve that opens and snaps shut are pretty quiet. Springers which have a huge spring that forces a piston forward until it snaps against the stop are decidingly less so. I suspect a good bit of the noise you hear is the action cycling and clanking in your HK.

Also, you would be surprised at how much a difference it makes from a distance. Like you said, up close you think...wow...not too quiet. But, further away the difference is huge.

As far as accuracy, I've seen POI changes and groups open up with no visible sign of strikes. I suspect it can be close enough to cause turbulence issues without actual contact.
 
I have a 92FS with a Knight Suppressor that I use wet (read water) everytime. It is quite quiet and works very well. With the addition of the sights on the can, accuracy has been excellent. Knock wood, never had any malfunction at all and this may be due to the non tilt operation of the Beretta as well. As a former LEO and a current reserve Deputy I can tell you that you can get a sign off even if we don't know you. The best thing to bring to the initial meeting is your CCP (permit) as it lets us know that you've been run through NCIC. I'm gonna do it again, but I at least know it's worth my time. In the dark house clearing qualifications it is amazing the advantage the suppressor gives you with reduced muzzle flash as well as sound reduction. Any suppressed weapon is louder in an enclosed area than they are in the movies, just reality. Using subsonic rounds requires a lot of practice for shot placement, it is more critical than ever. Thankfully the Beretta still is a natural point and shoot fit for me. I can shoot the 7 yard stage and 15 yard stage "over the sights" as well as using them.
