SIG Sauer M11-A1

If you were to name a SIG Sauer pistol in use by our military and law enforcement, it would probably be the P226 or P229. But there’s another SIG sidearm that also serves with our troops, various government agencies and local law enforcement officers. That’s the P228, designated as the M11 by the U.S. government.

At one time or another, the M11 has been issued by the Army, Navy—including the SEALs and Naval Aviators—Air Force, Secret Service, FBI, DEA and several other agencies. SIG Sauer now offers essentially the same pistol—but with a few noteworthy upgrades—to consumers as the M11-A1.

The M11-A1 is a solid, well-built pistol, which is no surprise considering its military lineage, and its mid-range size makes it a good candidate for concealed carry and personal protection. You can learn more about it by checking out the video below, hosted by Shooting Illustrated's Adam Heggenstaller.

I have a P228 that I picked up from a LEO. It was his backup firearm, and he was wanting a newer pistol. I have had no issues with my P228. I would snag another, or the new M11A2 if I get the chance to!

so the ability to penetrate a steel helmet is what makes a round superior? I thought it would be tissue damage, in which case .45 ACP all the way

Sig makes a fine handgun. This one, like the P228 and P226 is no exception. However, these models are fairly heavy and bulky for concealed carry. The polymer framed P250 is likely the better choice for concealment.

Love mine... I've probably put 3,000 rounds through mine and have never had a malfunction... except when a round without a primer snuck into the mag. I especially like the 'bar - dot' sights on mine... really easy to pick up the sight picture and very natural to point.

I have been shooting a 228 since 1990? I have no issues with this pistol after shooting several thousand round through it. No feed issues, no jams. Nice trigger out of the box and the grips fit my hand and it handles well for me. Great personal protection pistol. Very comfortable to carry and shoot.

SIG Sauer handguns are just plain the best. Period. I love my P226 SAS and my SP2022, both in 40S&W. Great quality handguns, accurate, reliable and get the job done.

Does anyone know if old style 13 round 228 magazines are usable in this new iteration of the gun, or conversely, if the new 15 round magazine will run in the old version?

The weapon has good and bad points. The original p228 made in Germany had much better workmanship and accuracy but unfortunately the cheap stamped sheet metal slide did not hold up to high pressure ammo. The more crudely made American model has a stronger slide but less workmanship and accuracy. The design has a lot of defects as well. The controls are placed way too closely together and those familiar with the 1911 will inevitably end up hitting the hammer drop lever instead of the slide release lever under stress. When field stripping the weapon one must be careful not to brush up against the small spring located in the upper rear portion of the frame or you will damage it. Also the main spring hangs down on the outside of the frame underneath the plastic grips. Dropping the gun or falling with it and slamming the rear of the grips can cause the main spring and strut to become bent which would put the gun out of commission. The gun is very poorly balanced and feels top heavy like a K-Mart electric hand drill and does not point naturally like say the H&K P30 or Walther P99. Cheap sheet metal roll pins are used in the frame which should be replaced if the gun is ever stripped down to the frame. Accuracy is acceptable, sights are very good and superior to the WWII very small 1911' sights and reliability is good under pristine conditions. If dropped in the mud, good luck as you cannot strip this gun down o the frame like a 1911 but the Sig does fit the hand much better than a 1911 and one can get at all the controls easily, something the average recruit cannot do with the gigantic grip circumference of the 1911. Trigger pulls on the Sig are superior to the WWII 1911's heavy, gritty trigger pulls. Caliber 9mm is superior to the anemic .45acp that actually bounces off of old style WWII helmets at ranges beyond 25 yards while the 9x19 goes right through them out to an astonishing 125 yards with ordinary ball ammo. Recoil and recovery time superior to the .45acp as well as the ability to carry more ammo because of the lighter weight and size of the 9x19 ammo. The Sigs aluminum frame is easily damaged compared to the WWII steel frame of the 1911 45acp.
