High Standard is the only US handgun to ever win an Olympic Gold Medal, back in 1960. Great guns, but the magazines can be finicky, as they are effectively the feed ramp, of the system. It can take a bit of bending, on the lips of the mag, with a fine point needle-nose pliers, to get things "just right". My Supermatic was out of commission, for a few months, after my sister slammed the magazine into the well, and bent the lips. Even my gunsmith couldn't get it to work right (and he grew up shooting High Standards for Bullseye). I finally got it fixed by tweaking the mag lips a bit more. My gunsmith, an NRA High Master, now shoots a Marvel 1911 conversion for the .22 portion of Bullseye. He says HS were the most accurate guns he ever shot, but he stopped using them years ago, because of the temperamental magazines.
Mine is a tack driver, and the most accurate handgun I've ever owned (in these tyro-hands). Yes, I shoot it weak-side, when it's wearing its ambi-grips (it came with these right-handed target grips with a thumb-rest).
