Wow, that is light.
I've run lots of Zero 180g JHP's at an OAL of 1.135in with 3.5g of TiteGroup. It usually would chrono toward 140pf, but felt like cheating.
I ran it in a Glock 35 with a stock recoil rod and spring. I would get the occasional failure to feed on the very last round in the magazine (with no other round under it to help position it for feeding). Always just the last round.
Brass would eject just a few feet and slightly forward (meaning the brass wasn't quite clear when the slide would start to close).
I loved shooting 40 for 10 round Minor (Production, Steel Challenge, whatever)
