My project to build a modern version of the Detonics Combat Master is complete. This is something I have wanted to do for some time, but couldn't work into the budget. Early this year a friend made an offer I couldn't refuse: He would buy parts for two guns, I would build them and he'd get one. Yes-please-and-thank-you!

While the original Combat Master was a fairly spartan affair focused on close-in self defense standards have evolved in the modern world, and those changes are reflected in these guns. These are somewhat in the category of a 'pocket race-gun' optimized to put accurate rapid-fire on target as quickly as possible.

I used Hellfire Armory alloy frames to keep the weight manageable, RIA 'Officer' slides and ramped full-support bull-barrels and components from EGW, Klonimus and Wilson Combat (mostly.) Fitting, de-burring and cutting the frames to size was necessary, but not an amount I would consider unusual. Front sights are Sig fiber-optics, rear sights are custom and made from aircraft aluminum. The sights are configured to allow the rear sight to be employed for cocking against a surface, belt etc. and offer good traction but won't gore you. They are serrated front and back at 40 lpi. Both guns have hand-cut 20 lpi checkering on the front of the grip-frame and under the trigger-guard. Both guns also feature ambidextrous safeties, functional grip safeties and mag-well funnels. Both guns are finished in Satin Black GunKote.

The grip-frame is slightly longer than the original, allowing even my meat-hooks to get a three-finger grip. I felt that the pay-off in comfort and control was worth compromising concealability a little.
I did not make the guns identical; Spice of Life and all of that. Here's some of the areas they differ:

The first gun has a modified checkered aluminum mainspring housing, a full-length dust-cover/rail and a grip-safety with a tiny bit of a tail; with my big hands I am always a little concerned that I will grab the gun a bit too high under stress. It's never happened with my original CM, but it's in the back of my mind.

The second gun has some changes-

This gun has the original lack of a beavertail and the frame dust-cover cut to the original length. I wanted something subtle and tasteful for the grips. ;)

Both guns have nice, crisp triggers that break at 3-1/2 lbs. with little take-up and almost no overtravel. The reset is super-short. The eight-round magazines have hand-made bumper-pads screwed to the bottom; on the first gun I used the same micarta as the grips. On the second gun they are G10. I used Mec Gar magazines for both guns on the advice of Peter Dunn, one of the men behind the original Combat Master.

Still working on my first cuppa' Joe, so I probably left a buncha' stuff out but that's why it's a forum; you can ask questions! Here's a few more pictures:

Here's a string of 7-yard double-taps from the test-firing of the first gun.

Really happy with how this project is coming out. Now that the coatings are done there's just a bit more test-firing and I can call it good. Which one is mine? I think the first gun, but I am going to let the fellow that paid for the parts choose. I won't feel abused in either case.
 
I've always wondered what the purpose was for moving the rear sight forward on the detonics.

It was assumed by the designer the gun would be carried with the hammer down on a loaded chamber and cocked during the draw. Not an unusual technique 40 years ago. The rear sight was moved forward to facilitate cocking.

Great job, especially the second pistol. The grips sorta hurt my eyes though. :)

Just so. I actually have a video about this very thing on mu You Tube channel.
