Range Report: SIG Ultra Compact 9mm

SIG Sauer Ultra Compact 1911 9mm pistol with a box of SIG Elite Performance ammunition

When it comes to the 1911, the full-size Government Model .45 is easily the type with the best reputation for reliability. It is more difficult to get the shorter Commander right, and it is even more difficult to convince an Officer’s Model size pistol to run correctly. Add in chambering the pistol in 9mm, and you have a whole new set of dynamics to work through.

It is somewhat remarkable that SIG has taken the 1911 9mm pistol and produced a completely reliable pistol with excellent handling. The SIG Ultra Compact is well suited to personal defense. While there is a certain amount of truth in the statement that a 1911 should be a .45 ACP, the Ultra Compact 9mm is a pistol that stands well on its own merits.

SIG Ultra Compact Features

SIG Sauer has taken the 1911 design and added SIG quality and consistency of manufacture. The result is a pistol you may bet your life on with a great deal of confidence. The pistol has several departures from the traditional 1911.

The most noticeable departure is that the 1911 9mm features an external extractor. This makes for improved reliability. There is nothing wrong with a properly tuned tool steel 1911 extractor. When have you had trouble with a SIG extractor?

The slide is nicely finished stainless steel. The aluminum frame is black anodized. The pistol features the usual 1911 grip safety, slide lock safety, slide lock, and magazine release. The controls are very ergonomic. The slide lock and slide lock safety are not extended, but they are easily manipulated.

The grip safety is a beavertail type. This safety guides the hand into the grip and helps lower the bore axis. Shooters who use the thumbs forward grip sometimes form a cup in the palm that rises off the grip safety. A well-designed beavertail grip safety eliminates this concern. The safety is positive in operation and locks sharply in place.

The barrel doesn’t use a barrel bushing (like many 1911 handguns use). With a shorter slide, the barrel must tilt more severely during recoil. Thus, the barrel bushing is deleted. In its place, the pistol features a belled barrel that locks solidly into the slide.

Front grip strap checkering is a custom-grade touch.

The checkered grips are either cocobolo or rosewood. They are well turned out and offer good abrasion when firing. The front strap is nicely checkered, as is the mainspring housing.

The trigger breaks smoothly with a 5.1-pound compression. Reset is sharp. The sights are three-dot types with tritium inserts. These sights are an advantage in dim light. The sights ride low — as a concealed carry handgun’s sights should — but offer a clear, sharp, sight picture.

The pistol is supplied with two 8-round magazines. These are standard 1911-type magazines, and in common with other 1911 9mm pistols with similar-sized frames.

The pistol turned in excellent combat groups.

The 1911 isn’t difficult to disassemble. Ensure the pistol is unloaded before you disassemble the pistol, of course. Then, simply lock the slide to the rear and remove the slide lock. The slide runs off the frame. Next, remove the recoil spring and guide, and pull the barrel out of the slide.

This is a handsome pistol with a nice two-tone finish. The finish was flawless, the controls were crisp, and the grips were well done. The pistol fired as smoothly as it looks.

Range Testing

I began the test by lightly lubricating the pistol over the long bearing surfaces, barrel muzzle, and barrel hood. I loaded the magazines with CCI Blazer 115-grain FMJ loads. I locked the slide to the rear and then dropped the slide on a loaded magazine by releasing the slide lock.

SIG’s 1911 9mm proved reliable with a wide range of ammunition.

Firing at man-sized targets at 5 and 7 yards, the SIG 9mm proved fast on target and fast to a first shot hit. The SIG Ultra 9mm is among the most controllable and lightest recoiling 9mm pistols I have fired. Combining a metal frame and the 1911’s straight-to-the-rear recoil results in a fast-moving pistol that gets good hits. Moving to 10 yards in offhand fire, I slowed my trigger press just a little and continued to blast the X-ring.

Accuracy testing is always interesting. I elected to test the pistol with its relatively short 3.3-inch barrel at 15 yards. Firing from a solid benchrest firing position and taking every advantage for accuracy, I fired five-shot groups for accuracy. The results would be exceptional — even for a full-size handgun.

For the final test, I fired the SIG Elite 147-grain V Crown — the only heavy bullet load tested. This load put five shots into 1.4 inches at 15 yards. This shows the pistol runs well and is very accurate.

During the range work, I used a well-made leather holster from FALCO. The Crab Hawk holster features belt loops that cinch tight, allowing for good concealment under a covering garment. The stitching and finish were good to excellent. The holster features a sweat guard, retention screw, and a reinforced spine.

The pistol’s combat ability leaves nothing to be desired. Reliability is faultless and the SIG Ultra is accurate enough for any chore a 9mm pistol may handle. The SIG Ultra Compact 9mm is light on the hip and easily concealed. If you are a 1911 fan, or simply value precision and control over magazine capacity, this may be the pistol for you.

  1. The P938 is a micro 9mm and the Ultra Compact is a larger and heavier gun, it is similar to the
    EMP 1911, I have had mine for 3 yrs and it functions flawlessly. It goes through aluminum case and brass and steel case ammo without a hiccup. On the negative side it is heavy, but is concealable.
    I prefer my Sig 365X for EDC as it carries 12rds as opposed to 9rds in the Ultra. I carry concealed
    and the 365X is my summer gun, and the Utra is my winter gun as it conceals easier with a jacket or vest. You cannot go wrong with either gun.

    The SIG Ultra is larger than the 938. While larger it isnt difficult to conceal, it simply isnt a micro compact like the 938. It is much easier to shoot well.
    Thanks for reading


  3. i wanted to intercede in brazil i am part of a shooting club our president wants to release weapons but the cogreço doesn’t want them anymore also they don’t give security for businessmen who pays taxes every month incredible isn’t it!!!!!

  4. This is very similar to the compact Kimbers. I have an RCP. But. with a barrel and slide that short, the butt needs to be rounded at the bottom end. MUCH more comfortable to shoot . Still snappy though.

  5. If there is a glaring negative for Sig, it is their infatuation with the NON-CAPTURED, open end rod, return spring design. The 938 is for sure a ROYAL PAIN when trying to get back in. A captured spring setup for the P938 would be a worthwhile aftermarket investment, if there is one. I actually prefer all the benefits of the original 1911 design return spring with NO guide rod, as it is much easier to disassemble and reassemble. Also the internal extractor design is much easier to remove for cleaning than the Sig external design extractor. That said the P938, a MICRO 9, is still a very comfortable carry.

  6. I was wondering if anyone had any information on a comparison between this Sig Ultra Compact and the P938. They appear fairly similar.
