Product Info for American Tactical Imports Match Grade Replacement Conversion Barrel Kit

This drop-in conversion kit takes your .45 G.A.P. Glock 37 and allows you to fire .40 S&W with a couple of simple part swaps. Comes with a match grade .40 S&W barrel, .40 S&W extractor, and either a .45 G.A.P. or 9mm follower. Once you have the parts in your Glock 37 swapped out, you will need to replace the .45 GAP magazine with a magazine for the .40 S&W (Glock 22 magazine sold separately). Using the standard .40 S&W follower will feed the conversion kit, but the slide may not lock back after the last shot. This is what the follower in the conversion kit is for, you simply swap the follower in your .40 S&W magazine with the .45 GAP follower and the slide will lock back as normal (on empty magazine).image
