I was watching Dallas Swat last night and they were talking about the hand guns they use. They showed Sig and said they use Sig 226 pistols. They said that for an little extra punch they use .40 shell casings that are necked down to accept a 9mm bullet. They showed the ammo and that's what they looked like. Has anyone here heard of doing this? Why not just use .40 cal ammo?
As everyone else has pointed out, it's called .357 Sig. It's meant to replicate the performance of .357 magnum in a revolver. It's a nifty little round, but like so many things that have come from the gun industry lately, it's a solution in search of a problem.
Another very similar round is the .400 CorBon - a .45 necked down to a .40. Has anyone on here ever fired one of those?
Yep! I wish it had become more popular....pretty expensive to shoot now. Since everyone likes pictures...here is mine:
Wow. I never knew anyone made production guns in 400 Cor-Bon. Figures that AMT would be the company to do it. They love oddball cartridges.
Not too bad considering its size. It actually weighs a fair amount and is ported; both of which help keep it under control. Its really meant for up close and personal...not really much for sights on it.
.40 S&W brass is thinner than 357 sig brass. Same diameter, but totally different ammunition. If you get .40 brass and neck it around a 9mm, it will look just like a 357 sig bullet. It's highly probably you will have a kaboom if you fire it, though.
