I still don't get the need for all those pluses and P's. Something like the Rem Golden Saber, Speer Gold Dot, Fed Hydrashocks in 124gr is compatable with ball training ammo and will sufficiently hand the job at hand and won't pre-maturely send firearms to the parts piles.
But yeah, if the manual says "Don't" then I always try to "don't" to the best of my ability.
