The power charge burns very quickly in such guns and say you have a 36 inch barrel. a bullet could in theory get stuck in the bore is the thinking. People use such guns in europe.It gave a barrel length limit on the site of 24 in I believe
I did not expect it to cycle through a semi at all
Yeah, none of my 22 pistols cycled without the suppressor. I don't know, maybe the suppressor is dirty enough to add sufficient back pressure. My Sparrow is pretty old (but probably has shy of 5K rounds through it), and I have never disassembled it for cleaning (too lazy and it works, so I leave it be)They make a quiet semi auto that is supposed to.
I tried the quiet in my buckmark today and it would not cycle - but was quiet.
