The Glock 26 will meet your desire for a smaller handgun. It is very accurate and easy to use. G19 mags work in it, as do G17 mags. I use an A&G grip adapter on mine since it forms a "bobtail" with a G19 mag. I keep all flavors of magazine available: flat based 10 rd, finger rest 10 rd (for faster grip acquisition in the appendix position and better concealment), Glock 12 rd mags (they are functional and look sharp--they make the gun look balanced) and G19 mags with grip adapters. I tend to keep a G19 mag as a spare on the belt and carry a 10 or 12 round mag in the gun.
