Suppressed Beretta 21A
Hello all. I have a Beretta 21A threaded. I have put both a Specter 2 and a Sparrow on it. Without a suppressor it shoots fairly well (for a micro-gun!) but wen suppressed, the group drops about 4" at 20'. That seems like an awful lot. None of my other 22 hosts have any change to speak of. I am using CCI Standard velocity in all. Is this common in a little gun or might something else be causing a problem? I realize it is what it is, but wondered what others think. Thanks again.

I have one with a sparrow on it and never thought about grouping it. Will have to try it.

I had a beretta 21 with a crimson trace laser. I was getting a fairly significant poi shift before I sold it. Couple of inches at 10 yds. Windage and elevation both. Nature of the beast would be my guess. I could dig out old targets. Pm if you are interested.

Re: Suppressed Beretta 21A
Just curious, how does a suppressor cause a drop in POI? Due to blowback? Something is causing a decrease in velocity, and apparently the shorter the barrel the more significant the drop??

Re: Suppressed Beretta 21A
Not necessarily the velocity. It can drastically change the barrel harmonics. On some guns it acts like a big muzzle brake as well. Or the weight changes the way the gun recoils.wmdaniel70 wrote:Just curious, how does a suppressor cause a drop in POI? Due to blowback?

I had a Contender .44 barrel threaded for a MAC can at one time. Unsuppressed and shooting from sandbags, the gun would recoil upward quite a bit. Add a 12" can to the end of the barrel, and it would recoil straight back - no muzzle flip at all. Think that made a difference on downrange POI? It only moved it down several feet at 100 yards.
As for the 21A, I really haven't shot mine much without the can attached. And suppressed, the can obscures the sights. I shoot with both eyes open and sight "through" the can. I find it fairly difficult to do with the 21A and its tiny sights. So it's really a short-range proposition. I keep thinking I need to get a Crimson Trace laser grip. I just haven't gotten there yet.

Re: Suppressed Beretta 21A
I have not chrono'd it; don't have the equipment. It does have Crimson Trace grips (Really helpful!!) that were aligned without a suppressor. With laser, nice group. Add can, still decent group but about 4" lower at about 20'.
Re: Suppressed Beretta 21A
I'm really wanting to do this myself ...ordered a tiny B22 can from HTA, thing is 3.75 x 1in tried it on a p22 and was pretty quiet, cant wait to get it out of jail, shot it at the dealer into a snail trap.

Re: Suppressed Beretta 21A
Best guess, the suppressors weight on the end of the barrel is tiltling it down causing your low POIwmdaniel70 wrote:I have not chrono'd it; don't have the equipment.

Re: Suppressed Beretta 21A
I have a 21A that was threaded by Accurate Ordnance that I run with a sparrow. With crimson trace laser, it will shoot dimes groups at 7 yards. While I've nailed opossum at 20 yards with it, I consider it a 7-10 yard setup. Anything outside of that, a Tacsol PAC-lite is a better setup.
Speaking to the POI shift, again, at 7-10 yards I haven't noticed any POI shift with or without the sparrow. I shot a few groups tonight with Gemtech's 42 gr subsonic was was pleased with the ammo.
