Flat Main spring housing with 20 LPI checkering for an improved grip on your 1911 Government or Commander model pistols (will also fit Para Ordnance and STI double stack pistols).
Looking to upgrade your 1911 22LR pistol? Most shooters like the feel of a flat main spring housing over the arched MSH that comes installed on your German Sport Gunworks or Sig Sauer 22LR handgun. Also by replacing the factory MSH housing on the GSG/Sig 1911 pistols, it will allow you to bypass the magazine safety.
NOTE: if you replace the main spring housing on your GSG / Sig 1911 22 pistol with ANY after market mainspring housing, you will need a standard Mainspring Housing Cap/Retainer pin found HERE.
Because of the design on the Colt/Walther 1911-22, you will need the following 3 items listed here if you want to replace the Main Spring Housing. (1) MSH Cap/Retainer Pin (2) MSH Retainer Pin and (3) Main Spring Cap
