that is the eternal dilemma, a compact LW 9mm with 12 or so +P 147 grain hard cast bullets, or the much larger frame size 10mm, however after watching the 10 shoot through all of the gelatin I am leaning to the G29 with 220 grain hard cast. OTOH even a glock 30 loaded with the Buffalo bore 230 grain hard cast 45ACP ammo at 925 FPS would probably be interesting.
