The Glock 43 does not include the RMR cut or the side window!
They remove the finger grooves and bevel out the inside of the trigger guard on a mill. As a standard upgrade they perform the aftermarket ACCELERATOR CUT™ frame service. The Accelerator Cut™ service offers enhanced traction on the pistol. After the Accelerator Cut™ service is performed, muzzle rise is dramatically decreased and follow up shots are faster. They do a non traditional double undercut and dock the front of the trigger guard to serve as an additional indexing point. they finish the frame off with full stippling and offer Glock® Gen 4 back strap melding as well for no additional charge.
All parts are cleaned & inspected, trigger bar is re-vamped, contact surfaces are smoothed and polished. The patented Agency Arms flat-faced trigger shoe is tuned/fitted, OEM minus connector, OEM trigger return spring, OEM striker spring, Agency plunger safety spring, assembly, safety check, Operations check, and finally test fire.
