Hello All, I just returned to the world of Glock by buying a G26 to supplement my S&W J frame. Yesterday was the first time with the pistol at the range and it worked great with 200 rounds of Remington 115g UMC. Before I left I also ran a magazine of Federal HST 147g (which I was planning to use as a carry round) and experienced a jam on round six where the empty casing was caught in the slide above the next round. Needless to say, I was pretty surprised. I had no more of the heavier ammo to keep testing. Is there a recommendation for bullet weight when a shorter barrel pistol is used? I would have no problems with using Gold Dot 124g +P depending on what you guys say.
