Since my other thread was so interesting, I figured I'd ask about 9mm pistols too. I have an M&P that I like, but I've only shot it once with a boosterized Isis and it didn't always cycle. Could be that I'm doing something wrong, but I may be interested in a different suppressor host.
i have a lot of luck with my Springfield XD 9. No issues with it feeding. It seems to be a pretty quiet host too. My Sig226 is great too, but it is definitely the expensive option.
