Machined steel firing pin stop is wider and thicker than standard, so you can gunsmith it for a tight fit that helps keep the extractor face square to the case rim for improved extraction and feeding. Bottom edge is left square, ready for final fitting to help slow slide opening and increase dwell-time with major power factor ammunition. Heat-treated to Rc 48, with radiused corners that resist cracking, for a long service life. Available in carbon steel with a tough black oxide finish and stainless steel. Series 70 is sized specifically to give a no-gap fit on .45 ACP Colt Series 70 pistols and clones. Series 80 fits 9mm/.38 Super/.40 S&W/.45 ACP Colt Steries 80 pistols and clones.
