The 10MM – Perfect ’10’ Hunting Machines

By Mark Hampton, American Handgunner

Most shooters are familiar with the ever-popular .40 S&W cartridge, but some of you may not realize this cartridge originated from the 10mm Auto. The 10mm actually started life as .30 Remington brass cut down and loaded with .38-40 bullets. The 10mm is an unappreciated and often overlooked cartridge still struggling a bit to catch on with mainstream shooters and hunters.

The FBI had a brief history with the 10mm in S&W’s Model 1076. Unfortunately the cartridge was a bit much for some agents, especially those with small hands. Norma offered high octane ammo in those days rivaling the performance of the .41 Mag, which might have added to the problem. When the FBI dropped the 10mm, a shortened, less powerful cartridge emerged as the .40 S&W we know today, courtesy of innovation at S&W. Luckily, Colt introduced the Delta Elite in 1987, a version of their Government Model, chambered for the 10mm. This decision probably saved the 10mm Auto from evaporating off the face of firearms history.

However, that same Colt had issues, and the powerful factory loads of the day often battered those early 10mm 1911’s badly, giving a reputation for being “too powerful” to manage. In actuality, the Colt needed better design elements to accommodate the cartridge’s power levels.

After writing a piece for the American Handgunner 2013 Special Edition on the Delta Elite, I became more interested in the 10mm. Colt had made critical engineering changes to the classic 1911 design to better mange the power of the 10mm, and I found the gun ran excellently. I thought it would be neat to explore several semi-autos chambered for this misunderstood cartridge and see what’s available today. In the process, I also scrabbled and scrounged a considerable amount of ammunition for testing the guns. Honestly, I was somewhat surprised to see the quality of both guns and ammo currently available in 10mm. Two of my handloads were also used during T&E. While impossible to get my hands on every 10mm Auto pistol, let’s take a quick peek at the ones landing on my doorstep.


The Glock 20SF is a big auto, and can do double
duty as a hunting or defensive handgun. Mark said
he’d put adjustable sights on it if possible.


Fourteen rounds of powerful 10mm can easily handle
a whitetail deer — or an attack by a biker gang!


Glock Model 20

This Glock has a strong following, among both self-defense types and hunters. Taking on a biker gang? This is the way to go. My test gun came in the form of their Model 20SF featuring a smaller grip diameter. This design is welcome for smaller hands. With a standard magazine capacity of 15 rounds, you could solve a lot of serious problems before reloading. It took a little getting used to the trigger, but once I shot the gun several times it was actually easy to operate. The slide release is small in design but painless to manipulate. Grips are textured and comfortable even shooting heavy loads. Right-handed shooters will have no issues with the positive magazine release.

Even with combat-style fixed sights I could keep respectable groups at 25 yards. As a handgun hunter I will opt for adjustable sights. Glock’s high-tech polymer frame handled recoil much better than anticipated. I never experienced one malfunction and we ran through a lot of magazines with different loads. The Glock 20SF can be concealed in a proper holster with edges smooth enough not to snag. If you like having the capability of firepower, the Glock 20SF delivers in spades. The gun came with two extra magazines. A great defensive auto for bear or bad guys.


Dan Wesson’s Razorback RZ-10 offers a 5″ barrel and top-
quality workmanship, reminding Mark of a custom gun.


Dan Wesson RZ-10

When I took the Dan Wesson Razorback RZ-10 out of the box I thought it was a custom 1911. It’s a good-looking gun for sure. The RZ-10 incorporates a match-grade ramped barrel feeding the 10mm rounds smoothly and reliably. The double-diamond checkered cocobolo grips contrast well with the stainless frame. Fixed defensive sights are machined into a serrated Clark-style target rib. At the range I found the sights quick to get on target. The black rear sight and black front blade did not interfere drawing the pistol out of Galco’s Jak Slide holster.

The flats on both the frame and slide were polished with a soft brushed finish, while the rounded portions were sandblasted. The back strap was finely textured, making a comfortable, consistent grip under recoil. The RZ-10 comes with two 9-round magazines. Running eight different factory loads through both magazines revealed zero mishaps. Accuracy was top-notch as might have been expected. This 5″ 1911 is a keeper. Dan Wesson falls under the CZ-USA flagship.



Kimber Custom TLE

The “TLE” stands for Tactical Law Enforcement II, and this well-built 10mm shoots as good as it looks. The 5″ match-grade barrel and bushing were responsible for impressive range results. I was able to manage several groups under 2″ from 25 yards and I don’t usually shoot a 1911 that well. The tritium 3-dot fixed night sights were easy to see. The Kimber features front strap checkering (30 LPI) providing a non-slip grip, and I liked the extended thumb safety in case you were wearing gloves in the field. The steel frame is finished in matte black. Front and rear serrations provide easy slide operation.

Grips are black synthetic and I could maintain a consistent grip under recoil. The trigger is an aluminum, match-grade version with serrations on the pad. The gun came with three stainless 7-round magazines. This Kimber functioned flawless with its full-length guide rod and 16-pound recoil spring. It also handled recoil well when shooting heavy bullets from Buffalo Bore and DoubleTap. No jams or malfunctions were experienced. I like the Kimber and will replace the fixed sights with adjustable sights for hunting.


The EAA Tanfoglio Witness Hunter (6″ barrel) was a brawny, dedicated hunting auto.
Below: Pre-drilled frame holes allowed a scope mount and the trigger had an adjustment stop.



EAA Witness Hunter

The Tanfoglio Witness Hunter from EAA, arrived in a very impressive lockable case with three slide springs, compact cleaning kit and one 15-round magazine. This is not your typical concealment or carry gun but a hefty piece of steel made for hunting. Fill the magazine full and weight will tip the scales over 3 pounds. Performance at the range was impressive, with some groups averaging less than 2″ from 25 yards. It’s a comfortable gun to shoot perhaps because of its weight combined with the CZ 75-style walnut grips. The grip is a little larger than a standard 1911. Checkered texture on both the front and back strap of the frame provide a solid grip under recoil. And it handles that recoil effortlessly.

I appreciated the longer sight radius on the 6″ barrel, and sights are large, target style and fully adjustable. The gun comes with an extra front sight for added height if needed. The slide comes pre-drilled for a scope mount, which was included with my test gun but I’m not sure it comes normally supplied. The Picatinny rail on the mount will accommodate scope or reflex optics making the Witness Hunter a nearly ideal hunting rig. Fit and finish appear superb. The Witness Hunter is single action, and while the trigger has more creep than I like, it will probably smooth out when it’s shot more. One feature standing out was the enlarged trigger guard — perfect if you need to shoot something when wearing welding gloves! Overall the Witness Hunter makes a serious hunting pistol.


Para USA’s Elite LS Hunter showcases a 6″ barrel,
excellent workmanship and stock adjustable sights.


Para USA

While we’re on the subject of serious hunting handguns, Para USA offers a well-built, 6″ match-grade, ramped barrel on a 1911 platform. The Elite LS Hunter comes with VZ Operator machined G-10 grips which are very comfortable and eye pleasing. Front and rear wide serrations located on the slide provide easy operation. A rail is featured for lasers and lights. I like the adjustable rear target sights with green fiber optic front post as they are easy to see with my aging eyes. I was shooting at a wild boar target at the range and the green front post really enhanced shot placement.
