Here's some of my 5” 1911s.
TOP RIGHT: Springfield Armory Mil-Spec CO2/BB airgun, stock out of the box. My new favorite toy! I can shoot it in my basement anytime I want for about 1c a shot, regardless of weather or other factors.
TOP LEFT: All-steel .45 built around 1985-86 on an Essex frame with WWII Ithaca slide, GI barrel, NM bushing fitted finger-tight, hi-viz fixed sights. Has fired @ 25K reliable rounds and will shoot 4-5” @ 50 yards. My “house” gun.
BOTTOM RIGHT: .22 Ceiner conversion on genuine 1926 Colt commercial frame. Frame is steel and slide is alloy. Hi-viz fixed sights. This one's seen somewhere around 20k rounds of cheap bulk .22 with very few problems, though it does need to be mucked out about every 2K rounds or it starts to get really sluggish. Lotta fun--especially when .22LR ammo was only 2c a shot.
BOTTOM LEFT: .45 on Fed Ord Ranger (lightweight) frame with Colt MKIV Series 70 barrel and bushing; hi-viz fixed sights. With light frame and full-weight slide, it's the heaviest recoiling 1911 I've ever shot. Really nasty! It lives in a bug-out bag with a homebuilt mid-length AR and a Mossberg 500 20” Turkey Gun.
The SA CO2 gun feels and operates identical to the others, though it's of course lighter than the all-steel gun. It's heavier than a LW Commander, but feels very similar in weight and heft to the two part steel/part alloy 1911s at the bottom of the pic.
