Signature Series 20 was first built on a 34 length slide as a proof of concept, with an angled nose and open windows in the front of the slide. We liked it as a prototype so much that we decided to offer it to you! It features a tapered nose, angled slide windows throughout, drastic weight reduction through scalloping cut-outs, and aggressive slide serrations for the best grip surface possible.Features: If slide shows as 'in stock' the slide is ready to ship with no waiting Bead blasted finish Made from 17-4 PH1150 stainless steel Made in the USA Fits Gen3 frames
