Some don't recommend +P because it will open the action too soon.
Yeah, it's rated for it. The ballistics by the inch is a good website for sure. The 230gr 45 auto out of 16" barrel doesn't gain much velocity over your standard 5" barrel. Lighter bullets gain about 200ft/s, at least from the sight information.
