Magazine Quantity and condition: This pistol includes 10 x Sig Sauer 13 Round 9mm magazines all in Excellent to Like new condition.

Overall Condition: This handgun retains about 99% of its metal finish. The action shows minor operational wear, as does the top of the barrel and barrel hood. The breech face has minor brass fouling and there is one very small nick in the magazine well. The screw heads are sharp, the pins unmarred. The markings are clear. Overall, this pistol is in Excellent to Like New condition.

Mechanics: The action functions correctly. The slide has very little play to the frame. The double action trigger is smooth, the single action has a smooth takeup with just a little creep before breaking. We did not fire this handgun. As with all previously owned firearms, a thorough cleaning may be necessary to meet your maintenance standards.

Box, Paperwork & Accessories: This pistol comes in a black plastic Sig case with serial-matching label, a total of 10 x 13-round M11/P228 magazines, an article by Jim Barrett about the M11-B model, and information collected by the original owner while he owned the pistol. There is also the original quality control inspection tag.

Our Assessment: While the P226 would ultimately lose out to the Beretta 92 in the XM9 service pistol trials, Sig’s P-Series pistols have still gone on to have a huge following in the commercial, law enforcement and military markets. Their P228 model has seen favor in the military for roles which require a smaller pistol than the M9, and the United States dubbed it the M11, seeing service in the Army, Navy, Air Force and by other DOD personnel. This is quite the rare opportunity at a commercially released M11 pistol, re-marked and sold as an “M11B” due to contractual restrictions on Sig Sauer selling M11 pistols. Produced in 2010, this pistol was made for an Air Force contract but there were approximately 50 pistols which did not make it to the Air Force. These M11 pistols had a “B” suffix added to the model designation for sale on the commercial market, and are in every other way an M11, from the folded-steel slide with welded breech-block insert to the M11 13-round magazines (please note, this pistol will not be compatible with current production P229-1 style magazines). For additional corrosion resistance, several small parts have a phosphate finish and the slide has a desirable K-Kote finish. Collectors of both Military sidearms and Sig Sauer pistols in general will not want to miss out on this M11B. Please see our photos and best of luck with your bidding!!!-R.L.
