Anyone run their 5 7 with a 9mm suppressor? I just picked up a 5 7 pistol and I am considering suppressing it. I have a Sparrow, but from what I have read it does not seem ideal. The O rings get burnt out very quickly and need to be replaced often, lots of blow back, mediocre sound reduction. I have no interest in buying a 5.7 dedicated can. I am thinking maybe it makes sense to buy a 9mm can which I can use on my 9mm pistols and use it on the 5 7 pistol as well. Thoughts?
