The Speer 124+p GDHP is used by the NYPD and the have documentation on actual shootings, documentation show the Speer to be a great stopper and great on barriers. My opinion based on actual shooting, and NYPD has a few, is any 124+p bonded bullet from the top ammo makers should do it. My choice only two 1. 127+p winchester, 2. 124+p Speer GD, speer has a little more flash but liveable. I would carry either. Oh and one other consideration, the 124+p GD loaded instead of 1220 fps but to a sizzling 1310 fps made by Double Tap. Harsh wear, expensive, reliable, harsh recoil, accurate, and 357 Sig power, I sprung my Beretta to shoot this load and has 16 in it as we speak. Recoil still not on par with a 45 and the only mind set you need is you may have to throw away you gun after a few years of a steady diet. When I can, still perfer 200gr+P GD in a 45. Oh yeah DT make some of those too, but I ain't throwing away my 45.
