Chubby,
My only first hand experience dates back the the late 80s with Glasers in 9mm. I belonged to a gun store/range, where one of the clerks and I were BHP fanatics. We both carried a BHP loaded with Glaser in the chamber, and the first two rounds in the mag.
A good friend of his was an Atlanta PD narcotics officer, and was arresting a member of a motorcyle gang, ie, a biker. The biker drew a weapon and began shooting at the narc who carried a BHP loading exclusively (carry mag) with Glasers. He hit the biker at least 3 solid hits high chest and noted they had NO effect at all. The Glasers were not penetrating the denim colors, and were doing no decernible damage.
The narc dropped that mag and reloaded with HPs and finished the shoot out in short order. When my buddy who was also a close friend of the narc told me, I stopped carrying Glasers period. Now they may well have changed a lot since the late 80s, but Mr. Murphy and I know each other too well as it is. I have no desire to invite him along for the ride.
My suggestion is a good GD, GS, HS, SXT or some other round you know will perform consistently. Just my thoughts, hope they help some.
