Kit Features & Upgrades
416R Stainless Barrel. The barrel included with each kit is precisely forged and cut from Crucible 416R stainless, one of the best gun steels available on the market. Featuring a 1:10 twist rate with 11-degree target crown and nitride treatment, your barrel will provide superior accuracy, wear, and lifespan.
17-4 PH Stainless Slide. Nitride- and heat-treated to obtain a hardness rating of 41-44 on the Rockwell C scale, your front- and rear-cut slide provides ergonomics, better control, and complete protection from corrosion and rust in the most unforgiving environments. Included open-leaf glow sights provide optimal sight picture in day and night conditions, making this slide perfect for the range, competition, and concealed carry.
Factory-spec parts kits. GLOCK® components are the most reliable, so it only makes sense to outfit each with kit 100% factory-spec parts, ensuring your build can be assembled without a hitch and will function with completely dependability for thousands of rounds.
