Osprey 9MM or .45 for Glock 17?

There is usually a small bit of difference between a 9mm and a .45 can when using a 9mm host (9mm is usually a hair quieter) but I'm not sure it's really that noticeable or important unless you're chasing dB's. If you're not going to be shooting .45 through the can, I'd probably just get a 9mm suppressor and leave it at that. However, if you think you might someday want to suppress a .45, I'd go with the .45 can so that you have the flexibility down the road.

Don't just think about pistols either. Something like a subsonic .44 Mag/Special out of a lever gun should be safe for a .45 suppressor (but check with the manufacturer first) and would be a very fun gun.

Most guns won't need suppressor sights to see over an Osprey, but some still might. Personally I don't see the need for suppressor sights, I just sight through the can when shooting suppressed.

You might still want sights. The Glock I tried an osprey with had tall-ish sights and I still couldn't see over the can.

FWIW, I was talking to a guy at liberty about an entirely different can, but still a 9mm or 45 can on a 9mm host. He said he liked the sound of the 45 can better.

If you don't plan on shooting .45ACP suppressed, I suggest getting a 9mm cam -- they are smaller and lighter. Osprey 45 was my first suppressor, I ended up shooting 9mm 147gr loads the most, so I got a 9mm suppressor pretty soon afterwards.

The sights "seeing over the can" issue is nowhere near as bad as you might expect at first. You focus on the front sight, the target is a blur and the occlusion of the target by the suppressor makes surprisingly little difference -- although some high contrast paint for the front sight might be in order. I'd try it as it is and only spring for "suppressor sights" if you really must.

In my humble experience, 45 cans are not 100% reliable on 9mm pistols with a browning tilting barrel. I am no expert, and have not done any sort of empirical testing. However, I have had enough stove pipes to prefer a 9mm can for 9mm.

Unless you have a super specific build going, getting a bigger bore can is most always a better idea. Heck, I got a .30 Griffin Recce 7 and have only used in on 5.56.

I have an osprey in .45 and in 9mm. They are fine cans, and either will do fine on 9mm. If I had it to do over again, I would get an Octane .45 and extra end cap for 9mm. The first round pop is annoying in the Osprey's, and find the Octane more enjoyable to use. The ospreys hardly come out anymore.

Is the 9mm Osprey capable of handling rifle rounds of the same diameter or smaller?

No. Uncorking pressure of rifle rounds other than .22lr and .300BO sub-sonic is way too high. You don't want to shoot .22lr through a can you can't take apart to clean. But .300BO sub-sonic jacketed bullets should be fine.

Read Mark White's book "Tactical use of low signature weapons for military and police" It has a lot of information.

BTW a 9mm and 22 and ARs usually all have the same TPI 1/2 in. x 28. I would never run a riffle round through a can that was designed for a pistol. MUCH more pressure with the rifle and you may "pop" your can or worse....

If you don't know what your doing put away your pride and find someone that does and or educate yourself. Good luck.

I feel it worth mentioning, you might be under the impression this may be the only suppressor you get, but once you go through the process once and finally get to pick up your toy, you'll want MORE.... So many more....
