I went to the range today to rent at Glock 19 as I was thinking of trading my XDm .40 for a glock 19. I was thinking of getting rid of the XDm because I wanted a pistol that could I could carry easier than the XDm. I test shot the 19 because I figured if I could shoot it better than the XDm then it was a win win. Well I shot it and it turns out that I shoot both the XDm and the Glock left. I also own a Walther PPS in .40 and I shoot that left as well.
After shooting a few rounds with the Glock I switched it out with an M&P 9mm. I shot the M&P 9mm left as well. However, I did not shoot it way left like I was with the glock, XDm, and PPS. I was only left by about an inch or so from where I was aiming. I may have to start looking into the M&P 9 as a possible replacement for the XDm.
On another note I carry a Springfield EMP 9mm and I am dead on with it.
