For what was to be a back-up gun, deep concealment piece, maybe to reduce gut gouging during draws ? Had a long half day, via text, discussion with three friends today. Two are combatives instructors, on A-IWB carry. So that kinda stuck in my head. The full size Detonics 1911s are constructed the same way, so I'm not sure about that theory.

The original designer that licensed the design to Detonics liked to carry hammer-down, and the relief cut on the slide was to facilitate thumb-cocking on the draw. I was told by another former Detonics employee that the cut on the original gun was shorter, but when Detonics made the production prototype the cut was wrong, and it was easier (and cheaper) to roll with it than it was to retool. I shot these guns a lot over the years, and it is my experience that the shorter sight radius and focal distance allows a faster flash sight-picture, which at close ranges is an acceptable trade-off for the slightly reduced accuracy. How slight is it? Well, in IPSC matches at ranges out to 25 yards I never noticed a difference in accuracy between Combat-Masters and a full-size guns, but YMMV. In terms of practical accuracy you can judge for yourself; the target is three double-taps at 5 yards. Yes, I jerked a shot and got a flyer.

The Scoremaster had an adjustable sight located at the back of the slide in the conventional position. There were some guns made by employees with the Combat Master-style slide cuts, but these were personal projects, not products offered by the company regardless of the fact that they often had factory markings. Many of the quality issues the company encountered came from inept employees who bought slides, frames etc. at cost and bodged together guns that they then sold to supplement their meager salaries.

The Service Master had a slide cut to maintain the Detonics signature look, but it was much shorter than the cut on the Combat Master; more like the original hand-made gun. This only moves the rear-sight dovetail forward about 1/4" compared to a stock Government Model 1911a1. This horror, the Street Master, was cobbled up by an employee on his own time and is not an official product. His theory was that since the butt was the hard-to-hide part when carrying concealed so he mated a chopped frame to a Scoremaster slide that had not yet been cut for the adjustable sight.

Generally if one encounters a weird Detonics it's not a factory prototype, but something made by an employee for their own purposes. The gun wielded by Sara Conner is a Terminator movie is an exception; it's a purpose-built blank gun made by Detonics for the 1984 Tom Selleck movie 'Runaway,' based on Raoul Bloom's Speed Master prototype that never went into production. The prototype used a Combat Master frame with a 6" Score master barrel fitted with a barrel-weight made from a modified section of slide. If I recall correctly the two blank guns were straight-blowback; the actual prototype .45 was locked breech and they never really got it working well.

I actually like that street master…
Bunch of us Glock folks wish they would do a 26 frame/19 slide combo. They went the other way, with a 17 frame/19 slide.

Thanks TP, for nailing it down.
