I have two suppressors, licensed and everything. One is for .22 or .223 and the other is for .45 (but will also work for anything smaller, like .40 or even 9mm.).

Here’s the deal: you can’t silence a supersonic bullet. But when you suppress it, it becomes very difficult to determine which direction it came from.

A .22LR is subsonic from any barrel less than about 14 inches or so in length. The less powder, the less the bang and the more it can be suppressed. A regular .22LR still makes a pronounced BANG even with a suppressor, but it is quiet enough to shoot in an indoor range without hearing protection. Same with the .45. But it isn’t quiet. It’s still loud but it isn’t loud enough to cause hearing damage.

If you really want to quiet a cartridge down, it takes really soft loads that skirt just below the sound barrier, and use just enough powder to get them there.

One of the important effects of a suppressor is that it changes the nature of the gunshot sound such that it is just a softened noise that doesn’t sound so much like a gunshot anymore. It’s still a thump. But not a gunshot sound.

Since the speed of sound is approximatelt 1129 feet per second, if I were to use a surpressor on one of my handguns, I would put a threaded barrel on my Sig P220 in .45 Auto and load it with my usual range Blazer range ammo, rated at 850 FPS.

Even some of the Cor-Bon +P runs at 1075 FPS. You still hear boom but no supersonic crack .

I’ve started the process for getting a suppressor last Thursday.
