Gratuitous pics of the Combat Master:
This 1911 has a 3 1/2" barrel and holds 6 in the magazine. It is not as dinky-small a gun as you might think - I can just about get all fingers on the grip, and I have average to largish hands. If I had someone relieve the underside of the trigger guard a little, it would be a full-fingered grip for me.
The "through the sights" picture is with the actual notched blade removed from the rear sight base, and just looking through the U-shaped sight base itself. The stock rear sight blade's notch is the same width (Edit: .39cm) as the front sight, which may be good for precision shooting but makes it slower to line up the sights. This isn't a precision shooting gun anyway. I'm going to try shooting with just the rear sight base, which is about 2X as wide as the front sight, and if I like it I'll leave it as is, or make a new blade with a wider notch.
