Upgrade or complete your PF9SS build with smoother-than-OEM pins.
Once you've finished your PF9SS frame, you need to assemble it with the frame's locking block, rear rail module, and build kit. The factory pins do the job well enough, but ROOK Tactical's upgraded stainless provides further improves trigger feel and the fitment of the locking block and rear rail.
Better pin fitment (thanks to tighter machining tolerances and a polished stainless finish) translates into smooth operation, cycling, brass ejection, and better trigger feel. Grab your dimpled pin kit and pair with ROOK's upgraded locking block and rear rail for a completely upgraded installation.
