With most things, silencers are about trade offs. 1. $$$ 2. how quiet 3. use with more than one cartridge. 4. maintenance Based on what I have read.... Degrote 1. $$$=ok 2. how quiet=ok, but there are better 3. use with more than one cartridge.= pretty good. 4. maintenance=not good for an all day range session, but great for one box of 22LR and then a box of 9mm.
