That depends. Sometimes I carry a Para-Ordnance P14.45 filled with 14+1 rounds of Winchester 230 grain Ranger SXT JHP ammo. Other days, I carry a Taurus PT-92. That is usually loaded with 15+1 rounds of WInchester 127 grain Ranger SXT ammo.
Oh, and then sometimes I carry an EAA Witness 10mm, with 15+1 rounds of 165 grain Golden Sabre JHP ammo from http://www.reedsammo.com
