Lone wolf barrels - Lone Wolf Arms AlphaWolf Glock 41 .45 ACP Threaded Barrel, .578x28

This was my fourth Lone Wolf Barrel, and Optics Planet was the only place I could find this particular one: for a Glock 41. Every Lone Wolf barrel I have purchased has fit better and shot better than factory Glock polygonal rifled barrels. For example, the threaded barrel I installed into my Glock 21 transformed that gun from a 6 to 8 inch, vertically strung group into a tight 2 inch ragged hole machine with No other modifications. The fit and finish is phenomenal, and accuracy improvements are obvious as soon as you start shooting. You simply can not find a better drop-in improvement for a Glock.
