Super's the one that needs all the special care, personally I'd be reluctant to shoot +P/SMC in anything not a steel frame.

Big difference between Super and SMC is between the primer pocket and if I recall right SMC has a thicker casewall turning some of the "unusable volume" into reinforcing metal so you can safely use more of the remaining volume.

At least, IF I understand Fernando Coelho right from back when he, Mr. Bane and I were haunting AmBack twenty-odd years ago...

I'm not recommending anyone else shoot .45 AP +P ammo in an alloy frame, but .45 +P is less than 2/3 the pressure of standard 9x19mm ammo, and no one gives a second thought to shooting 9mm in an alloy frame. A lot of people will even shoot +P+ 9mm in an alloy frame, and that's 83% higher pressure than .45 Auto +P. Even the lowly .22 Long Rifle has 1,000 psi higher pressure than .45 ACP +P ammo.

Granted, I am also admittedly overcautious... twenty years and a grand out of a live-in caregiver's budget is a big gamble.
