Any quality modern handgun rated for SAAMI 9x19mm +p specs should be able to handle the occasional diet of RA9TA (and similar major-brand +p+ ammo) without much trouble. Certainly it will accelerate wear but it won't kill the gun in a day.

I've shot plenty of it through Glocks, Berettas, SIGs, and M&Ps without any trouble.

When I was at Beretta, we actually had a letter we sent to LE agencies telling them that internal testing showed +p+ ammo from the four major manufacturers produced less wear on the gun than standard NATO-spec 9mm (M882).

The S&W M&P9 was specifically designed to handle RA9TA. The little teardrop cut you see underneath the striker channel in the breechface is there due to early testing with that load.
