Like other reviewers, I bought this barrel as an experiment to get my P365 XMacro Tacops up to Glock 17 / full size pistol ballistics out of a gun smaller than a Glock 19. With the XMacro series you're packing 17 rounds, so why have a short 3.7" barrel? It looked a bit ungainly too, and I'm a sucker for good aesthetics! I paired this with the Ed Brown 1/2-28 nitride thread protector (sold on OP also) since this barrel doesn't come with one, and the flutes in the protector look purpose-built to contrast with the slide serration cuts on the P365 series slides! So now my Tacops looks like its actually ready to operate operationally (and tactically). But the more important question is, how does it shoot?! Well, with a mounted green dot on the slide, at about 12 yards I was getting same-hole or holes-touching groups resting the pistol on my side-by-side bed rail while sighting in, and that was not purposely trying to shoot small groups. I then ran out to 25-30 yards on steel, offhand, and it was boringly easy to smash the plate every time. I need to bench-rest the pistol and shoot for 50 yard group on paper to see how it does with some match ammo. In short, I see no reason to spend $150+ on a barrel for your 365XL or XMacro (seriously, SIG should have made the XMacros in 4" barrels and slides at least, if not 4.5). The 365 series beats the pants of the P320, its a better gun in all regards, and simpler.
