If you like striker guns, there are plenty on the market. Glock is certainly the old reliable choice, although there are plenty of like M&P's offerings.
If you're open to other mechanisms, that really opens things up. It depends on if it's meant to be a carried gun or some other criteria which would help narrow it down. For a carry gun I lean towards something smaller even if it sacrifices the best comfort when shooting. I'd rather something easier to actually carry. For that I like the LCPMAX. It's double action only, which gives it the same simplicity and consistency as a striker. Even though it's DAO, the trigger pull is actually pretty similar to a Glock's weight. It is in .380 though, so if you want to keep all your current 9mm you can go for the slightly larger LC9.
So if your only pistol was the m18 and you were a civilian, what would you replace it with?
