Which is the better round and why? Does anyone think that the 357 sig is here to stay or that it will slowly die out? what would you pick and why???
lighter bullets in 40S&W shoot flatter.
While the Texas DPS adopted the 357 SIG several years ago, the Dallas PD did not. In a head to head competition, the Dallas PD selected the 9x19 Ranger T (RA9T) over the 357 SIG as their issue round.I've carried my P229 in 357sig for several years now. The Texas DPS and Dallas PD liked it well enough to adopt it.
While the 357 SIG tends to feed reliably, so does the 9x19, .40 S&W, .45 ACP. The bottle-neck design of the 357 SIG offers no advantages in terms of feed reliablity, but rather has a differerent set of feeding issues due to its design. The 357 SIG is a good, effective round, but it does not "tear the hell out of what it hits" any better than the 9x19. In fact, the 9x19 and 357 SIG consistently deliver the same permanent (crush) cavity. On the other hand, the .40 S&W consistently delivers a larger permanent (crush) cavity than the 357 SIG so, in fact, the .40 S&W "tears the hell out of what it hits" somewhat better than the 357 SIG.I like the caliber because it's fast, accurate, it feeds reliably due to the bottleneck case, and it tears the hell out of what it hits.
The 40sw and 357 sig guns are simply 9mm guns rechambered for the more powerfull calibers. They were only strengthened in areas that they had to be so they would not fall apart.
guns like the 9mm P226 and P228 and P225 get rolled steel ("lightweight") slides since that is all that is needed for the little 9mm pressures
You are putting out some bad information here. The 9x19 P226 has a forged stainless slide just like the .40 S&W and 357 SIG versions. Of course, the 9x19 versions of the P229 and P239 have forged stainless slides as well. I think if you do a little checking, you find that even with +P+ (which you do NOT have to go to equal 357 SIG performance) the 9x19 still has considerably less slide velocity than the 357 SIG. I doubt seriously you'd shoot a P228 to pieces even with +P+ 9x19 any quicker than you would a P229 with 357 SIGs--and even then, it would be the frames that would go not the slide.This isn't quite true either in all cases in my opinion, ie in the case of my SIG-SAUERs at least, guns like the 9mm P226 and P228 and P225 get rolled steel ("lightweight") slides since that is all that is needed for the little 9mm pressures, where .40/.357 P226s and the P229 and P239 get the much heavier forged stainless slides that noticeably weight down the gun.
