I had a box of grizzly 90 grain for the 357 sig (Glock 31) and had the chrono set up shooting some of my 90 grain loads to compare. Mine loaded mid level produced 1700 fps, but the grizzly's were hot, @ 1925 fps. I looked up the data for grizzly and they list the stuff at 1900 . Not a fun round to shoot that hot. All i can think of is that little bit of guide strips holding the slide on. LOL. I think mine were more accurate mainly cause i wasnt flinching so bad!. Energy calcs out to 721 ftlbs with a 90 grain bullet.

I was thinking not so much about slide guides but about the thin barrel chamber and throat area where the high pressure is. Gotta wonder how much pressure that load makes.

i notice even the glock barrel is a "fully supported" chamber in this round. Much different than the 40 s and w
