Springfield Armory 1911 Ronin PX9121L 10mm Auto

This Ronin 10mm Auto is a no-nonsense 1911 with a good, sights, trigger, reliability, and accuracy. This is a Best Buy for those wanting a 1911 in 10mm Auto.


The 10mm Auto is a powerful cartridge. When the 10mm is loaded to its full potential, it produces magnum-caliber revolver energy, and depending on the bullet and velocity, it can best the typical 357 Magnum load and come in just below the typical 41 Magnum load. That’s hot. It’s a powerful and effective round, especially in a semi-automatic.

The hapless Bren Ten was the first semi-automatic pistol to be chambered in the round back in 1983 by Dornaus & Dixon Enterprises. The second gun to be chambered in the round was the Colt Delta Elite in 1987. The 1911 platform is strong, and after a few fits and starts early on with cracked frames, Colt was able to adapt the 1911 platform to the cartridge. Part of the problem with the 10mm Auto is the pressure, which is about 37,5000 psi. The 357 Magnum has a pressure of about 35,000 psi, and the 41 Magnum has 36,000 psi. The pressure literally wants to destroy guns. Since the 1980s, other manufacturers have introduced 10mm striker-fire pistols, handguns based on the CZ-75 design, DA/SA models from Smith & Wesson, and other 1911 models. We wanted to take a look at the 1911 platform in this hot round, so we procured three 1911s chambered in 10mm Auto — a Springfield Armory (SA) Ronin, Kimber Rapide Black Ice, and Rock Island Armory Pro Match Ultra 6″.

The Springfield Armory 1911 Ronin (bottom) has an understated retro look with just the right features.

Factory 1911s can have quite a bit of variation from pistol to pistol in trigger feel and quality, as well as slide-to-frame fit, and the blending of the thumb safety and grip safety. Typically, the lower the cost, the less workmanship that goes into the 1911. Remember, a 1911 needs to be hand built and fitted. It is not like today’s striker-fire guns that are easily assembled. The hand-fitting is also why some 1911s are finicky about ammo and running smoothly.

All three of these 1911s are very similar. It’s the details that separate them. The SA and Kimber feature 5-inch barrels, and the Rock Island Armory (RIA) does them one better with a 6-inch tube. The RIA and SA have thinner grips and no magazine well, while the Kimber grip is thick, and it has a magwell for smoother reloads. Another common feature are highly visible and usable sights. The RIA goes a step further with a fully adjustable rear sight, while the Kimber and SA have driftable rear sights.

How We Tested

We did experience a failure to eject and a failure to slide lock back on the Kimber, but that was with the first magazine. From then on, no issues. The RIA also experienced an initial failure to lock the slide back. We attribute these issues to needed break in. After those minor hiccups, the pistols ran flawlessly. The Springfield ran flawlessly from the get go.

We averaged 1- to 1.5-inch five-shot groups at 15 yards across all three pistols. There is a reason why many shooters like the 1911 platform’s single-action trigger. With all of these pistols, we were able to shoot our best groups under 1 inch using a rest. In many instances, holes overlapped each other. With more range time, we are certain we could easily tighten the groups with any of these guns.

Ammo used during testing consisted of Federal Premium HST 200-grain JHP defense rounds and two training rounds; Magtech and Armscor loads with 180-grain FMJ bullets. All three of these loads cranked out of the muzzle doing a respectable 1100 fps, on average. This is powerful ammo, and when we tabulated the data, we found it accurate as well. Using a rest, we fired at Thompson Trouble Shooter targets set at 15 yards. All three pistols showed good to excellent accuracy. The RIA was exceptionally accurate, with many tight groups showing touching bullet holes.

Recoil was stout, so don’t think a 10mm Auto is for the faint of heart or recoil shy. The Kimber and RIA have front grip strap texture that helps with grip control. This additional texture helps to prevent grip slippage from recoil when the gun is fired. These guns did a good job of recoil management, and the RIA offered faster follow-up shots due to the extra weight.

From the shooter’s perspective, the Springfield Armory offers excellent defense sights with a contrasting front sight, a red fiber-optic tube. The sights on the Springfield Armory were also practical for the ledge that could be used for one-hand cocking.

We tested the guns’ fast-shooting qualities at 15 yards using a plain 8.5-by-11-inch white piece of paper with a 2-inch black square printed in the middle. We fired fast, at the edge of control, and we were able to keep rounds on target. We needed to lean into the pistol because recoil is fast and snappy, and it can get away from you if you are not paying attention. You don’t want to shoot a 10mm fast standing on your heels. We stood on the balls of our feet with knees slightly bent. Most fast-shooting groups we could cover with our hand. We also noticed the web of our hand was getting a workout. No abrasion from any of the guns, but we did notice some grips were more comfortable, namely the SA and the RIA. The Kimber grips have a high cool factor and were comfortable, but not as comfortable as the grips on the other two guns. Some of our testers grip a 1911 and ride the controls, meaning a right-handed shooter will rest the shooting-hand thumb on the thumb safety and the thumb of the support hand on the slide stop. Those with average to small hands noticed the larger grip circumference of the Kimber compared to the SA and RIA, and in some cases needed to change their grip for better trigger control. We also swapped magazines between guns to see if we could trip up any of them. We had no feeding issues.

That’s the high-level view of these 10mm pistols, now let’s get into the weeds.

Gun Tests Grade: A


We have tested SA’s Ronin 1911 pistol chambered in 45 Auto a few issues back and graded it an A- due to a single, odd malfunction that was most likely due to a magazine. We had no such issues with the 10mm variant, and that is why we give this pistol a solid A rating.

There is nothing particularly fancy about the Ronin 10mm Auto. It has a classic two-tone finish with a matte-stainless receiver/frame and blued slide. There is no accessory rail, and we feel there is no need for one if this gun is to be carried concealed. The finish was well executed and what we expect from Springfield.

The Springfield (top) uses a G.I.-style muzzle bushing, which we like and appreciate.

The front sight is a red-fiber-optic pipe that contrasts nicely with the two white dots in the Tactical Rack rear sight. You can rack the slide by using the rear sight as leverage against the mouth of your holster or some other object. We really like the huge notch in the rear sight because it makes it easier to acquire the red dot front. The rear face of the rear sight was serrated to reduce glare. These are excellent sights for a defense gun or action-pistol competition. The slide sports front and rear angled serrations that allow for easy press checks. They also provide a good grip when racking the slide. A G.I.-style bushing makes for easy disassembly, and there’s no need for extra tools or a bent paperclip to capture the recoil spring.

The matte-stainless frame/receiver has a smooth front grip strap. The mainspring housing is finely checkered. We would have liked serrations or a less aggressive texture on the front grip strap for added grip adhesion. The grips are Ahrends-style with the lower front of the grip checkered and the top rear smooth. The strategy here is the area of the grip in contact with the web of your hand does not get eaten raw from the checkering during recoil. Did we mention the 10mm has recoil? These are excellent grips. These grips are also thinner than the typical G10 grips on newer 1911s.

The Springfield had more of chamfer on the magwell, making reloads faster with the SA faster than the RIA.

The trigger is SA’s new Gen 2 skeletonized trigger, which operates the same as Gen 1 triggers. Both have a short reset, but the Gen 2 trigger has four holes, while Gen 1 triggers have three holes. On our sample, the trigger broke at 5.8 pounds, which is okay on a defense pistol. We would have like it between 4 and 5 pounds. The trigger face was serrated.

This pistol also uses a 24-pound recoil spring, which is heavier than a 9mm and 45 Auto variant. Our sample came in a soft zippered nylon case with one eight-round stainless-steel magazine. To rack the slide took 20 pounds of effort. The match-grade barrel is stainless and had no wiggle in the bushing. Slide-to-frame tolerances were tight.

The Springfield Armory has a smooth front grip strap. A bit more texture here would be appreciated.

The beavertail grip safety shields the delta-style hammer spur, preventing hammer bite. There is a single thumb safety with an oversized serrated lever, which worked perfectly. One way SA keeps the cost down on the Ronin is not installing an ambidextrous safety nor providing more than one magazine. Only one stainless magazine with a bumper pad comes with the Ronin. We would have liked two magazines. An extra mag ($28; Springfield-Armory.com) is not that expensive. The grip safety has a fairly large bump at its base to ensure the safety is fully depressed with a proper shooting grip.

The thumb safety is also nicely blended and smooth, so as the pistol recoils in your hand, there are no sharp edges to abrade your hand. The magazine button is serrated, and we would have liked it checkered and a smidge taller for a bit more friction when operating it fast.

Where the Ronin showed its stuff was at the range. The sights and crisp, consistent trigger helped us shoot best groups that measured 0.8 and 0.9 inches with the Federal and Armscor ammo, respectively. On average, groups measured between 1.1 and 1.6 inches. In speed shooting, we found the thinner grips helped those shooters with average to smaller hands control the pistol. The red-fiber-optic front sight was also easy to track on the black-and-white target.

Our Team Said: Recoil was noticeable with the Ronin, but it was easily managed. This is a no-nonsense self-defense 1911 in a serious chambering. The grips, sights, trigger, and cost easily make the Ronin a Best Buy. If you want a 1911 in 10mm for self defense, the Ronin is an excellent choice.
