The 3.2 Speed Strip Kit by Majestic Arms consists of a patented 2-piece bolt stop pin, a precision machined hammer and a new pivot bushing. The new pivot bushing reduces pre-travel of the trigger by 65%. Once the Speed Strip Kit is installed, disassembly is as easy as unscrewing the new bolt stop pin with the provided Allen key followed by sliding the bolt out for cleaning. The Speed Strip Kit will readily convert your Ruger auto pistol in a matter of minutes. The kit does not require any special tools or modifications to the pistol, nor does it interfere with any of the pistols normal functions. Installation of this kit will reduce trigger pull to 3-1/2 to 3-3/4 lbs. The 3.2 Speed Strip Kit also allows Mark 3 owners to safely omit the magazine disconnect feature.
