It looks like a good weight, solid point design with a fair meplat, tapered for easier reloads? But, the one on the left, if .38 cal. looks like a Beast! VERRRY Interesting indeed... What is the minimum expansion speed? I saw a report on XTP ammo that said the 125 and 158 gr. needed at least 850 fps to expand reliably, which would eliminate use in a lot of short barrel guns. But, getting hit with even a non-expanding bullet at 800-900 fps would be a great deterrent, I would imagine. Until something provably better comes along, the XTP, Speer 135 gr. 38 Spl. +P short barrel or the Remington Golden Saber 125 .38 +P will do just fine.
