This is the M1911 A1 by Rock Island Armory, a .45 caliber handgun with a 10 round magazine. I show a quick take down only. Reassembly is done in reverse order. I have a compensator on it from CKG: http://www.customkillergrips.com/1911accessories.htm
The grips are a rubberized tactical grip (one piece).
