After some experimenting with other suppressors for the FN five-seven pistol and the HK MP7 round. Our agency guys tested a number of suppressors which worked well but were larger and louder in comparison to the one that worked best. It actually ended up being a 22 can. Anyone here use 22 cans on larger caliber hosts. Just figured I would ask to see if anyone here has did this and if there was any probs after prolonged rates of fire. So far its taken the abuse with no probs. Thanks in advance. Everyone here is always so helpfull.
