I recently bought a .22 cal end cap a fixed barrel spacer, and a fixed mount for my revolution 9 pistol suppressor. In fact those parts just arrived today and I've been eager to try it out.
Here is some discoveries so far:
=======
Regarding ammo I tried several different kinds but in the .22LR world it seems like there are a few different approaches that make a HUGE difference.
Ammo 1 was sheerly a light bullet and maybe a little bit of extra priming compound and no powder. Yes this is subsonic and very quiet but it will not cycle the rifle. I didn't like that idea at all so I just stayed away from it. I doubt I will even test it.
Ammo 2 was a standard 40 grain bullet where someone at the factory decided they would just back off the charge a little bit. Yes it is subsonic and EXTREMELY quiet. I mean pellet gun quiet. I could hear dirt impacts 100 yards away. I experienced a lot of stuck cases though. Out of two 10 round mags I had 4 or 5 stuck cases. It would not cycle the gun at all and in some cases would half cycle and cause a few minor issues. I don't recommend this type of ammo at all.
Ammo 3 was a heavier grain bullet. 45 grains and loaded up like a regular round (I guess). I tried two different brands both marked 'suppressor' and they functioned flawlessly. As quick as I could hit the trigger it was cycling and spitting out brass. Someone in the ammo world finally made a proper round that checks all the boxes.
The last ammo was slightly (and I mean SLIGHTLY) louder than the previous but the trade off is that you can shoot it freely without hassles. My guess is the increased pressure slightly bumped up the sound signature. That said the difference was noticeable but not a big deal especially considering what you gain.
=====
As for the suppressor it was in a word... awesome. Since Silencer Shop didn't formally test the Revolution 9 on a .22LR I don't know the specific numbers but they did do a test on the optimus (which would be similar performance I would imagine).
The Optimus tested on a 10/22 out at 117 DB*
*(this test was done at equivalent of the K configuration or short version of the suppressor whereas I shot mine full length-- if it matters which I think it would)
The Griffin Checkmate QD (the new monocore one) tested at 115 DB
By comparison the Gemtech Mist tested at 112 DB
Anyway by any comparison they are all right there pretty close to each other when it comes to shooting on a rifle. I will test later on with the 9mm end cap and see if that makes any noticeable difference. My hunch is that it will because it traps the gasses in the can for a bit longer. At least that's my prediction.
The only real trade off I can see is that the Revolution 9 is 1.35 inches in diameter and the Checkmate QD is 1" in diameter. The Revolution 9 in full size configuration is 7.6" whereas the Checkmate QD is 5.95". Being perfectly honest unless you're shooting iron sights the bigger diameter MIGHT get in the way some. Length wise it is 1.65" longer in the full configuration. However in the K (short) configuration the length difference is only .15 inches.
I will do some more shooting later on with the 9mm cap and see if my theory is correct and I will shoot it in the K configuration and see if it makes any difference as well.
=====
Overall my impressions are not just good... they are great. I think that can will see a lot of .22 action as well as lot of 9mm too. The only real accessory I have left to get is the 3 lug set up (and a 9mm SBR of some sort[:D])
All this said on a .22 pistol I think the differences would be more, however based on Silencer Shop's numbers the Optimus (again only a reference point) comes out at 122 DB on a .22 pistol whereas the QD comes out at 119ish DB. But I think the size and weight would make a bigger difference on a pistol than on a rifle.
In either case we are talking that they are within just a few DB of each other in real world testing.
