Any browning tilTing barrel action will require a booster. Makarov, h&k p7, some walthers have fixed barrels, desert eagles have fixed barrels as well. Most of the pistols you would want to suppress will require a booster. Glock, 1911, cz 75, fn, ect.
My suppressed p322 with an oss rad22 is an absolute blast to shoot. Suppressed 22 with subsonic ammo is Hollywood quiet and ideal for pests around the property. Can hand it to anyone and they can shoot it without noise or recoil concerns.
The atf can come and inspect if they want, but if they want to pay you a visit they will wether you have an nfa item or not. Just ask David koresh, or randy weaver.
