I own Sigs P225, P228, P226 and P938 that are all very nice shooters.
Also, Glocks 17, 19, 26, 34 and 43, I've got 9mm Glocks covered and all of them are very reliable.
Lastly, own a Ruger LC9s that shoots good but has some kind of trigger slap against my trigger finger that I find painful after 50 rounds. But in a defense situation this would not be an issue.
