I have heard from a few sources that putting a silencer on a fixed barrel blow back design would disappoint. The models I had in mind were a p232, Bersa and a PPK. I only found a barrel for the PPK, so that is my only choice. Does anyone have experience with suppression on these types of guns? According to the manufacturer of the silencer, it would work just find..... and James Bond didn't haveany problems. Something about gas and other gunk escaping through the ejection port...... but I just don't see how that would actually happen. When I think blow back, I just think of the barrel also working as the guide rod.
