as far as the glock being Ambi, from what I can recall it was comfortable to hold, at least I dont remember it feeling awkward, when i reloaded I just switched hands to hit the mag release load an new mag and rack the slide then brought it back to my left hand.
While in a range setting not a big issue, but just for overall gun control I’d like to see if its possible and comfortable to maybe use my midle finger in my left hand to hit it, whether or not hitting the release accidently would be to much of an issue, or down the road just start training my right eye and right handed grip
