So back to the 10+1, if you can shoot the 45 just as well, might as well have the bigger holes.
Well when the BHO ban come, I will retire my G17 and start carrying my Springfield Armory M1911A1 pistol with nine round of 255gr LSWCs. Not much will stand up to those loads. A 255gr semiwadcutter going a mere 850 FPS.
