Ah. Matches and top competitors. Ducktail safeties and high grips with thumbs pointing at the target. I see. I suppose those things require compensation in gun handling.
By conservative estimates, I've probably fired a million rounds through various 1911 pistols over the last 55 years. No upswept safeties on any of mine. The spot weld afforded by the standard safety tang works the way it was intended. I've never bumped a safety on, and I've never seen anyone bump one on. The only one that I've known to bump on was Gray Wolf's Les Baer, and that was because a burr on the sear foot was grabbing the safety lug under recoil and refusing to let go. She wasn't toughing it with her thumb. I knocked it off with a file and by her reports, it's been fine ever since.
I tried that thumb pointing grip a few times just to see what it was about. It weakened my grip to the point that I couldn't control the recoil well, so I abandoned it. Maybe it doesn't work well for Millie, either.
