5SAO Single Action Only Aluminum Trigger

5SAO factory trigger CGW modifies for pre-travel, so it will have pre- and over-travel capability.  Supplied with a trigger return spring installation slave pin and 1.5 mm allen wrench.

NOTE: Installing this part in a firing pin block model (75B, 85B, 97B, RAMI B, SP-01, etc.) without the short reset system may result in a loss of the single action reset. We also recommend removing the disconnector when converting from double action.
