I have 2 PMR30 pistols and recently installed, in one of them, several MCARBO upgrades: Mag Release, steel Feed Ramp, square Aluminum Trigger, and metal Slide Release. After getting them all installed and reassembling the PMR, all functioned normally EXCEPT the safetylever can now be moved to the SAFE position without cocking the hammer. Prior to all my mod upgrades, that was not the case. The unmodified PMR will not allow engagement of the safety on the unlocked pistol. Huh? Any one have any suggestions?
