.357sig is hot. will get 1350fps. sport car of pistol cal
Just a opinion. But I would stay away from this round. I have a barrel for it for my glock, and 1000 pieces of brass. I reloaded for it. It has problems with the short neck and lack of neck tension. It will push the bullet back in the brass and can cause severe pressure. I know factory ammo will have more neck tension, but after seeing what I seen reloading, its the hardest round to work correctly I have tried I would never buy it.
I had to buy the sleeve for a 9mm crimp die, and put in my 40 S&W crimp die, and put the hardest crimp I could.
Also, looking at the energy numbers, and even Power factor numbers, the 40 is so much better of a choice.
Figured I would share my experience with you guys.
