Re: What would cause inaccuracy when hot?

Are you using cast slugs? The additional back-pressure caused by the can may be causing your barrel to overheat, and this could cause erratic performance. Even without cast slugs, an over-heated barrel will cause accuracy problems.

Re: tons of junk coming from suppressor into pistol action

Increased back-pressure is an inescapable side effect of adding a suppressor ( There are some manufacturers that say otherwise, but I think they are Commies...) Effectively, your action is opening too soon, and the gas pressure is causing that mess flying back into your face and dirtying up your gun...

Re: 9mm Suppressor (no tools)

Giving the gentleman the benefit of the doubt, I would think that he he could build suppressor from one of the "Filter kits" with little more than a hand drill and one bit. I can't believe that anyone in America does not have at least a cordless drill, and if they don't, I suggest this kind of a pro...

Re: just tried out form 1 9mm, S&W MP9 won't cycle AT ALL with it on

"I would think a suppressor if anything would add gas pressure" It will indeed add gas pressure, but the added mass hanging on the end of the barrel in other than a fixed-barrel weapon can prevent the slide from unlocking. A "Booster" also known as a LID, for Linear Inertial device may be needed to ...

Have you done any of the mods, to quiet them down? There are a couple.
Do you have suggestions for modifications to the upper assembly itself?

Okay, taking all these considerations into account, let me pose the following statements and questions: A Suppressor built for .22LR may have a "bore diameter" of .251 or even larger, and therefore physically permit the launching of projectiles .223, .251, .250, etc, irrespective of the cartridge na...

I was not aware that it was illegal to fire a .25 caliber projectile through a can registered and built a...

There were a few people building threaded barrels for the various tip-up Berettas. Unless you can find one , my guess is that Capt Link is right, and you will have to do a little fancy lathe work.There is no reason that I can think of that would prevent you from firing your .25 through a .22 can, as...

Re: Eccentric when wet?

Water is cheap, but there are lots of ablative fluids. Wire pulling gel is common, and sometimes is repackaged as special super-secret silencer juice. Lithium grease is popular since it won't drip out the muzzle when its holstered, but you end up wearing quite a bit of it when shooting, and its very...

When you make a M/M adapter for internal threads, do you thread the internal threads left hand, or right handed? I don't suppose that anyone makes adapters and tools ( Piloted reamers, etc.) like the CNC Warrior kits?

Yes, you can get "movie quiet" suppression in a relatively small package. I suppose a lot depends on your expectations. You will have to be willing to put up with a can that is both wet and wiped.

Even if the suppressor part was cancelled out by the muzzle brake part, i.e, the device actually made the report louder, or it just broke even, it would almost certainly still be a "silencer" in Federal eyes, since it would clearly constitute intent to manufacture a silencer, even if it did not work...
