This is the M1911 - Colt .45 semi-automatic pistol.
I know it is not exactly to scale and lacks the trademark notch on the forward slide, but the geometry was proving very tough when I was modeling it. So now, it has the appeal of the M1911, but can be used as a 9MM handgun if you want. People have told me it makes a great Glock!
I designed it in a CAD program, and had an ABS plastic injection mold made. The mold can produce these in ABS plastic - just like Lego does.
HEY WILL! I didn't know you had a MOCPAGES site! Oh, and I finished your Brickarms movie. I just got a MXL 990 Mic and still need to do the voices. I'f you'd like to see some of my creations, you can click on the link above. And this is a awesome M1911 I own 2 of them in silver and use them all the time! Luke
