$40 shipped USPS CONUS. Used/prepped Springfield Armory metal injection molded (MIM) delta hammer/strut/sear from MC Operator pistol that might have had 200 rounds through it. Set them up as spare but never had use for them. Hammer hooks are .020", I removed the MIM mold release blemish/ILS cocking ledge above the half cock notch to prevent ILS ledge from bumping sear at hammer drop. Sides of hammer/sear that contact frame have been polished with Crocus cloth. Sear legs squared for even contact with disconnector paddle. Hammer strut has been thinned to prevent contact with sear spring during movement. Areas polished by prepping cold blued- original finish is SA Armory Kote®. PayPal preferred.
