I wouldn't skimp on a 45 can. The only two worth buying IMHO are the AAC Ti-RANT 45 or the SilencerCo Osprey 45. It's worth it to pay just a little more for something you will have forever. Plus those cans work equally well on 40 and 9mm hosts. Not worth saving a buck on NFA when the best of the best isn't overpriced.
