I bought a 23 a couple of weeks ago and today picked up a 22. I'm basically moving up from shooting 9mm. I traded in my 26 to help finance this purchase. I was also going to trade in my 17 but started feeling a little sentimental about that gun and held on to it for now. I also purchased a Storm Lake 357 sig conversion barrel for the 22. The conversion barrel was $98 from Topglock. I bought WWB 125g ammo and a 31 mag so I wouldn't get the ammo confused. First, I put 50 rnds of 40 S&W WWB 165g and a mag of Remington GS 165g through the 22. Compared to the 23, the recoil was noticeably lighter. The 22 is a larger pistol so that is to be expected. I had my timer with me and practiced drawing from my holster and placing a shot in the -0 circle of a IDPA target from 10-4 yards. The 22 performed flawlessly. Next, I swapped out the barrel and installed the 357 barrel. Other than the barrel being stainless instead of black, you wouldn't know it wasn't totally stock. The 22 performed flawlessly, just as if it was a 31. In total I shot about 25 rnds of 357 through it. I have never shot 357 before and would say, personally I thought it had about the same recoil as 9mm +P+. It certainly wasn't any stronger than 40 S&W and was more of a "push" like 9mm. I'm really happy that now I can shoot 2 different calibers with the 22. I have a set of Meps I'll have installed; an extended slide stop and I'm going to install a 35 mag release and see how I like that. Also, all of my Glocks get a NY trigger spring. I really like the consistent pull and positive reset. All in all, I am very happy with my move to 40 S&W (and 357)!
