I have put a lot of rounds down range over the years. I used to own a Glock 23. It shot a few inches to the left for me at 25 yds. I ended up buying an adjustable sight and adjusted it all the way to the right. I also had to put the rear sight in the far right side of the dovetail. After a lot of rounds, I ended up selling it. My suggestion is to buy a pistol that works for you instead of "learning the Glock". There are far too many good pistols out there to fight one that really doesn't suit you. Glocks are fine pistols, but they aren't for everyone. I don't have that trouble with the Sig P 320, Kahr CM-9 or other semi auto pistols I own or have owned.
