Springfield Armory V10 Ultra Compact 45. Alien Gear IWB. I prefer the 1911 platform .45 although I have other carry options like a Glock 30 in .45 caliber as well. I just recently changed to the Alien Gear and I like the fit and feel of the Alien Gear and the ability to adjust the drag on the pull of the handgun and change can’t angles. Breathable material keeps the sweat down during summer. The rig however can be a pain to release from my belt when attempting to take the rig off.
