Detonics 1911 Combat Master

There is very little new under the sun. When we dive into history, we find the steps of our predecessors are the same steps we take. We repeat things. We make small advances. And we think we are the first. We think we have made giant leaps, yet we are mere mouse steps from our grandfathers. We do better to look back and learn. Such is the story of the today’s installment of Throwback Thursday: the Detonics Combat Master and the subcompact Glock.

Subcompact History

Nineteen years before Glock graced us with the magical Glock 26 and 27, Detonics was doing it first. Taking a full-sized combat gun and cutting it down to a size more easily concealed. This was also being done in 9mm by ASP and Devel using Smith and Wesson semi-autos, but not in the big boy 45 ACP.

Many years before that John Henry Fitzgerald, the Archangel of Colt Mfg. was chopping small bores and big bores alike. In fact, Colt shipped its first big bore double action snub-nosed revolver in 1924.

It was not a new idea, there were SAA’s built short for concealment before that. It was just a new execution, and right in the middle was Detonics. They were building something new, built on the old idea of a small hammer that hits like a big hammer.

Detonics Combat Master 1911

I really wanted to try out a Detonics Combat Master and see for myself what it was like to shoot and carry the first commercially available subcompact 1911 pistol. Now for the hard part… finding a Detonics Combat Master in good condition.

I hit up a buddy, Jesse Starnes of Double Star Corporation, and convinced him to let me borrow one of his. Jesse delivered big time. He sent me four 1911’s. Two Detonics Combat Masters and two newly built badass 1911s from Double Star (more on those later).

The Combat Masters came in both flavors, blued and stainless, and both appeared to be damned close to brand new.

The blued gun had the same blue hue as a nice Belgian Hi-Power, and the stainless…well it looked about as good as a brand-new gun.

It’s always good to have a friend who has a collection deep enough to have new guns from 40 years ago.

Detonics 1911 Combat Master Performance

Plenty of guns make sense on paper, some make sense in a magazine, but it’s the rare beast that makes sense in the hand and even fewer that make sense when you lift them to eye level and see the sights.

The Detonics is that rare beast. The sight picture comes up so naturally and clear that this 40+ year big old bore makes most modern compact handguns look crude and unrefined. Its capacity of 6+1 rounds doesn’t seem like a huge disadvantage when the first round is going to be a perfect hit. It just points that naturally and the sight picture is dead on.

Yet there is a cost. Recoil. This beast hits back, just like any other compact, big bore gun.

It is not by any means an everyday shooter. Anyone who joyfully plinks with it is off a little or enjoys pain. It’s not as brutal as a super lightweight .357 snub but it takes more work to control the beast.

This is where the magic comes in. It’s so much like the full-sized gun, that the practice you put in with your full-sized 1911 or your commander helps with how you shoot the Combat Master. Same controls, same manual of arms. What you learn with one, transfers over to the other. This also means it’s easier to use under stress than a completely different platform.

Then there is the issue of reloading big. When you top off the Detonics, you can use a regular or even an extended 1911 magazine for 8 or 10 rounds in a reload. You can even share mags between it and your full-sized duty gun.

Sounds familiar? It was the big selling point for carrying a pair of Glocks. A Glock 17 and a 26 make for a heck of a pair. I personally carried a Glock 22 and 27 pair in .40 S&W because we issued the .40 S&W. I bought the 27 because it was the best backup gun as it fed from the same mags as the 22.

Just Look at the Detonics 1911 Design

The Detonics played the same role almost 20 years earlier and it was chambered for 45 ACP before we had the reliable bonded jacketed hollow points we now enjoy. Glock didn’t get around to a compact .45 until 1997, 21 years after Detonics did it. When we look at a Detonics Combat Master beside a Glock 27 it is easy to see they share some similarities in the size department.

When we compare their full-sized counterparts, however, it becomes clear there is something just right about the size ratios. It’s no doubt in my mind someone at Glock was paying attention to the past when they designed the subcompacts. Even the subcompact Glock’s use of a dual recoil spring was something first used in the Detonics.

Hand Fit

Even now almost every subcompact 1911 built uses conical barrels and a bushing-less fit. Again, something first found in the Detonics. The bushing-less fit was a hand fit. The proof is found in the hand-scribed serial numbers on the barrel in the stainless gun and the slide of the earlier blued gun.

I checked with a friend who used to work at Detonics back in the early Washington era and he confirmed they hand fitted the barrels. His wife surprised him with a Combat Master a few years ago for his birthday and he made a set of stag grips for it.

Then there are the two things the Combat Master is known for. The rear sight moved forward and the “loaded magazine indicator”.

The rear sight was simple.

Based on the tactics of the time the designer wanted to carry the gun hammer down on the safety notch with a loaded chamber.

He designed the gun so the shelf behind the rear sight was a sort of runway to use the off-hand thumb to cock the hammer during the draw. Old fix for old tactics. Oddly enough it makes for a hell of a good sight picture. As good as other famous designs like the H&K P7 series.

The loaded magazine indicator was a different story.

To get the magazine to work properly and to cut it low enough for the gun they had to leave a gap for part of the follower to stick out when fully loaded with six rounds of 45 ACP.

Later some guys realized it worked as a tactile and visible indication the magazine was fully topped off. Some guys even painted the ends of the follower red with model paint to make it more of a visual indicator. It was a happy accident at best, but it worked.

Detonics was, for a while, the best of the best.

It was the most concealable big-bore backup gun out there. It hit hard, was a shootable platform that was familiar to serious shooters, and it even took spare mags from full-sized guns. The gun was plagued by early reliability issues that were hard to fix back then, in no small part because it was a new design.

Once the kinks were worked out, however, you could tune one up and even do a good trigger job and have an excellent hard-hitting gun that concealed well.

It was smaller than a Charter Arms, five-shot Bulldog in .44 special, and it had two extra rounds. It hit harder than the Devels and the ASPs which ran 9mm.

Not bad for a gun which while a bit heavier than a D frame Colt in 38 Spl, was practically the same size.

Detonics as a company went through three phases, 1976-1987 in Seattle Washington, 1987-1992 as New Detonics in Arizona, and 2004-2007 as Detonics USA in Georgia. Most “in the know” gun guys I know say to stick to the Washington guns, and they warn the earliest guns may be unreliable without work. This should not be a problem you’ll have – most of us will be lucky to ever see a Detonics in the wild and if you do the prices go a bit high sometimes.

Yet you might get lucky and find a Detonics 1911 sitting at a pawn shop just waiting for someone in the know to come in and adopt it. With a little love, it can still do the job if you can. On the plus side, it is just a great-looking old-school classic 1911 and a top-notch piece of history.

  1. they were crap in 1981/2 !
    you had to do about $600 dollars worth of smith work to get them to work after you paid $600 for it back then. (A Colt Gov’t model cost about $350 back then and it WORKED out of the box).
    The recoil spring and slide pull on those were difficult on them also. Better NOT have sweating hands or you could not jack the slide.
    I can say they were cute and “nice to carry”. But you could also buy a Colt LW commander back then which was the same size, held ONE more round and had the alloy frame. I owned them. (the Colt Govt, Colt LW commander, and the detonics.) I got rid of the detonics and I ruined the commander unfortunately.

    1. Spot on Bob! I was a LEO and combat shooting instructor when the Detonics hit the street. Our department issue was a full size Colt 1911. I acquired a Detonics and ran it through the paces. Our duty rounds were Silvertips (which performed poorly in a protracted firefight involving numerous officers and was later replaced). The Detonics stacked the Silvertips consistently. Switching to hardball was a little bit better, but there were still numerous feed problems. My take? Interesting, but too unreliable for a professional gunfighter. Interestingly, when the Detonics hit the street in the 80’s, there was another compact .45 which had been around for a few years that was a little bit larger than the Detonics but much less expensive and much more reliable. It was made by Star Bonifacio of Spain and was called the Star PD. I bought one in 1981 and found it to be a reliable off duty carry. Unlike the author of this story, I am not a Glock a holic. I prefer SA .45’s and 9’s. But I have owned a Kahr PM 9 for 20 years and I am very fond of it. IMHO…it carries and shoots head and shoulders above the Glock.

      1. too bad they still don’t make the Star PD. they were good.
        You might be interested in finding a Kimber Polymer Target 1911. It is 1911, has a polymer frame and holds 14+1 of 45 ACP
        Also known as a Bull M5 I’m told.
        My kimber is my CCW. I have about 23,000 rounds through it now and it works fine.
        I just had it professionally refreshed with new springs and polishing the feed ramp etc. Handles any ammo I throw at it.
        My Colt Gov’t model from the above post will feed an empty case even..

        1. Like you Bob, I am a Kimber fan. Around my ranch I pack a Kimber Micro .380 for coyotes and such. I’ve had to pop a few rounds at yotes that were cruising through during the day. Not a lot of horsepower behind the .380 but it gets their attention. When I go to town I usually open carry my Kimber Micro 9. I’m not familiar with the Kimber Poly, I’ll have to look that one up?

  2. I remember reading about them when the author Jerry Ahern wrote a series of books called “the Survivalist” I was a poor starving student who had just bought my second handgun an AMT hardballer serial number less than 200. Sold it as a gun MD I respected said ” no good gunsmith will work on stainless steel pistols” times shure changed.
