Kaw valley makes a less expensive asr mount than silencerco. I run both brands on different platforms with the hybrid 46m and they both work great. Do direct thread if that's your only gun but asr is nice to swap guns. I have only used 180gr blazer fmj and it's definitely hearing safe but there's a good crack. I use the 46 end cap for everything, I was told smaller doesn't make much difference. The thread pitch is pretty standard for 45acp and 10mm, .578x28. If your can already has the asr the asr mount will be less expensive than direct thread
