The Mauser M2 is dimensionally similar to the SIG P229 pistol, also manufactured by SIGARMS. Unlike most SIGs, it utilizes a rotating barrel like a Beretta. It's also striker-fired, like a Glock pistol.
It uses short barrel recoil with rotating barrel locking. The handgun has DAO trigger with striker firing (no hammer). Mauser M2 features numerous safeties: automatic firing pin safety, trigger bar dis-connector, loaded chamber indicator. Moreover, the manual safety is available as option. The manual safety is located in unusual place - at the rear side of the frame, under the place where the hammer usually may be found. Also, M2 features aluminium alloy frame with steel slide and replaceable slide rails.
M2 is reported as a comfortable, compact sidearm. The only minor drawback of M2 is its rotating barrel, that requires good lubrication of the rotating barrel to operate properly.
