I was the first to say something non positive about +P but in actuality I don't say anything negative about the round I just don't like the recoil in a G30SF. In a G21SF the recoil is just fine.
Nothing wrong with +P just don't think it adds enough to what is already a big slow moving hunk of lead.
I am not a subscriber to the +p will batter your gun to mush school of thought, in fact I wish I could shoot enough +P to break a Glock - sadly that isn't likely to happen.
Enjoy the +P its fine ammo I just wouldn't carry it in a G30 or G36.
