When I first started carrying a handgun, there were virtually no small single-stack 9mm pistols. The S&W 3913 was one of the only options I could find; but I had a bad experience with another 3rd gen S&W so that was out of the question. And now, thankfully, we have so many great options! From memory, here are a few...and I know I'm forgetting some.
- Kahr has several, with the PM9 being one of my favorites
- S&W M&P Shield
- Glock 43
- Walther PPS
- Springfield Armory XD-S
- Ruger LC9
- Keltec PF-9
- Several single actions (e.g., by Sig, Kimber, Springfield Armory, etc.)
