I have a left-handed friend looking to get a pistol... Naturally I want to recommend a Glock - but is there anyone that can give direct left-handed-shooting experience with the Gen 4 pistols (or perhaps an old thread to point to -- I didn't find any with my searching)?? pros/cons, recommendations/limitations, etc? For example, I know there's the reversible mag-release, but is the slides-stop release an issue for lefty shooters? Thanks for any insight!
