Few pistols combine collectible history with serviceable design like the Mauser M2. For shooters and collectors who value mechanical quirks and build quality, this pistol is a standout: it blends Sig Sauer pedigree, unique mechanics, and a factory-complete package that’s ready to own or shoot.

MAUSER M2 The Mauser M2 is a Mauser-branded handgun that was offered in the United States by Sig Sauer. This self-loading double-action pistol was originally chambered in .45 ACP, with later offerings in .40 S&W and .357 SIG. It’s dimensionally similar to the SIG P229, but departs from most SIG designs by using a rotating barrel system like Beretta and a striker-fired trigger system like Glock. This particular example comes in its original matching hard case with the owners manual and two magazines, described as mint with a minty bore. Shop this product

Design and mechanical notes

The Mauser M2’s rotating barrel is a defining feature. Compared with the short-recoil tilting-barrel common on many service pistols, a rotating barrel can reduce perceived recoil and improve barrel lock-up consistency. Coupled with a striker-fired action, the M2 delivers a crisp, predictable trigger pull while retaining the double-action/self-loading heritage in its ergonomics and controls. Dimensionally similar to the P229, the M2 will feel familiar to operators who appreciate compact, controllable service pistols.

Caliber considerations

The original .45 ACP chambering gives the Mauser M2 stout stopping power and manageable muzzle flip when paired with its rotating-barrel geometry. For buyers considering alternatives, later models in .40 S&W or .357 SIG broaden mission profiles—.40 S&W for a balance of capacity and punch, .357 SIG for higher-velocity performance. Select the caliber that matches your intended use: target, duty-style practice, or collector display.

Collector value and provenance

Sig Sauer purchased the Mauser name in 1999, produced the M2 at the Mauser Oberndorf plant, but imports ceased in 2004 and the facility has since closed. That manufacturing provenance, plus the complete factory kit—hard case, manual, and two mags—adds tangible collector value. At a listed price of $750.99, this mint example represents an attainable piece of late-era Mauser/Sig history. View product details and pricing
