1911 Mainspring Housing Flat Black Polymer
1911 and 2011 pistol mainspring housing with no arch flat Checkered Texture plastic polymer

STI black polymer plastic flat main spring housing with checkering for an improved grip on your 1911 Government or Commander model pistols (will also fit Para Ordnance and STI double stack pistols). Since this MSH is constructed of plastic, it reduces weight and makes for easier fitting.

Looking to upgrade your GSG or Sig Sauer 1911 22LR pistol? Most shooters like the feel of a flat mainspring 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.
