These guns are quite solid, and if well maintained might take it, but IMHO it'd be risky.
First of all, the gun wasn't designed for loads like that....
Secondly, why? "Bragging rights" don't count.... SD use pretty much allows you to get away with about any JHP that'll feed. If you want better penetration (and expansion), consider the newer loads with plastic fillers inside the hollow point.
If you must use those +P and +P+ loads, buy a new gun that's built for 'em....
