Kahr makes a couple sub compact 9mm (one poly, one not), kel tec PF9, and the Taurus Slim 709. My 709 has 1200 flawless rounds through it, and at $369 new it has exceeded my expectations. Adjustable sights, accurate, thin. You'll get the obligatory Taurus bashers saying if you buy one you will have to poke yourself n the eye with a stick, rub yourself with garlic, burn it at the stake, and have an exorcism...but I've loved mine. Any very small 9 mm is going to have a lot of recoil and have somewhat limited capacity. My Bersa Thunder 9 ultra compact is slightly larger but as easy for me to carry (and 13+1). It absorbs recoil easier and is easier for me to be accurate with follow-up shots. It's not the smallest, or lightest, but all things considered I like it a lot.
