9 mm gun, what to get?

It shouldn't jam EVER. Unless you are shooting junk like Herters and Wolf. Like I said, my Beretta was ok and is of course a solid choice. The military wouldn't use them if they were junk! I am of the opinion though that there are other choices out there that are easier to shoot due to weight (poly frame alternatives) and trigger pull. It sounds like you already made your choice.
