It runs very well, but I'm not really sold on the accuracy nor recoil/muzzle rise damping aspects of it. The accuracy isn't horrendous, but I think the stock barrel might be a shade better and I'm NOT a horrible pistol shot. I just really like the supported and tightened chamber from a reloading standpoint. The sad thing is I shoot my buddie's stock Gen III Glock 21 and 20 better than my 23 with either barrel, w/less felt recoil in both .45 acp and 10mm. They're both a joy to shoot and I will end up buying them both in the semi-near future (along with a .460 Rowland kit for the 21).
I actually want to sell the 23, but if I don't, I may buy a Lone Wolf Alpha Wolf or Wilson Combat barrel for it and give it a go to see if they're any better than the Storm Lake. I did notice that the S.L. barrel has VERY noticeable reamer marks in the lands and grooves. IDK if that's my issue or not, but J.B. compound made for only a slight improvement from stock. I need to slug the barrel and make sure that it's not sized a bit large or small for a .40 as that may be the issue.
