Then there’s its sister and mother cartridges the .40 S&W and 10mm respectively, the magazines for which will fit the same number of rounds — the .40 being one of the three most common handgun calibers in the world (which the .357 SIG really should have rendered obsolete were it destined for greatness), there’s just no hope for the .357 SIG as far as popularity in the foreseeable future. While the .357Sig is by far my most enjoyed round to shoot I only carry it when I travel in the car, meaning road trips. Life isn’t ever going to be that easy though, and superior ballistics doesn’t necessarily mean a particular cartridge/caliber is better than another. 1. stopping power equal to the .357 Magnum, the cartridge Evan Marshall and Ed Sanow deemed, in their book “Handgun Stooping Power”, best manstopper in actual shootings, As to ammo availability, it is readily available at $15-16 a box of 50 on line. It was never designed for this purpose. Joined: May 1, 2009 Messages: 384. I like that u attempt to prevent the continuation of the never ending caliber wars. All Rights Reserved.

As Sylvester Stallone so eloquently put it in Rocky VI, “The world ain’t all sunshine and rainbows!” This is the sad truth, and doubly more so in the case of the .357 SIG. July 10th, 2007 After forty years of firing handguns I sometimes wonder when common sense will prevail. Again, for 3 seasons in urban areas I carry one of my 9mm but the .357 sig absolutely has a place in the gun world especially where power, accuracy and penetration come into play. Gotta love ’em SIGs. Today on Kentucky Ballistics we shoot some soft body armor with 9mm, 357 Sig, 10mm and 5.7x28mm! A hit with a 22 beats a miss with a 45. Anyway, long story short, it’s right back to “WHERE” someone is shot, not the caliber. It accomplished this by taking a 9mm bullet (.355 diameter) and sticking it in a necked down .40 S&W case. The .357 magnum was so awesome that SIG Sauer, a Swiss-German firearms manufacturer, attempted to duplicate its ballistics when fired from a 4-inch barrel revolver by cutting the 10mm Auto’s case and necking it down to accept a .355-inch bullet (the same projectile for the 9mm). Re: 9mm +P+ vs 357 Sig vs 357 Sig +p+ « Reply #10 on: December 07, 2009, 07:14:05 am » Grant: You brought up something I'd overlooked on converting a .40 S&W to a 357 Sig … You need a oal of 1.2 in for those to be at there peak power. Thumbnail: shootout with a Meth Head blasting us, he was hit 9 times within 12-15 feet, both lungs punched out, one hit through the neck severing his carotid artery and he ran like a zombie in WW 3 MOVIE. The rounds expanded to about 0.60 inches, but had a higher muzzle velocity of 1300+ FPS. The 9mm is a 35,000 psi, +P is 38,500 psi and +P+ is 40,000 psi. Damian, thanks for reading the article. Please watch the following 2 videos below in their entirety and just maybe if you can put politics aside you will understand how the 9mm though a good round and can get the job done in most cases is not the perfect defense round that people want it to be. GND is community supported. That’s why we used .40 cal before. So what was still available? Thank you again for your messages and I’m happy I could bring a little laughter your way. Coy Getman I’m sure all of you (and maybe a few of you participated too) had noticed that 9mm rounds were being gobbled up like tiny white marbles in a frantic game of hungry hungry hippos. I don’t see this point in most discrediting articles for the cartridge. Also working outdoors in the woods of Maine, it has its merits against…larger wildlife that a 9mm, .40 or .45 would just piss off due to less penetration. Looking at the 7.65x21mm’s and the 9x19mm’s ballistics performance, it’s obvious that the former is superior. Let's get some things straight: Shot placement is the crucial factor. The casing for the .357 Sig pistol cartridge is nearly … It is very coincidental that I own both guns you have pictured (sig p239 in both calibers) and enjoy firing the sig 357 much more (and find myself carrying that more) but your conclusion hits the nail on the head when it comes to availability and affordability. I’d love to have a subcompact semi-auto in .357 SIG. Point being…no matter what you carry, today’s druggies are jacked up and don’t drop like in the movies. In a recent article, I wrote about the Glock 19 vs the SIG P229 9mm, both of whom I own, but my father recently hooked me on to .357 and I’m considering switching the P229 or even my Glock 19 gen 4 to that caliber. Plus the fireballs it makes at twilight hours is a bonus :p. Thanks for reading through the article. ? It’ll only be a matter of whether the owner would be okay with reaming the barrel’s chamber to accept 9×23 Winchester or just sticking with .38 Super. The 125gr HST in .357 Sig also met the FBI’s penetration guidelines. Able to hit 1400+ feet per second out of a proof barrel, it certainly accomplished its goal of reproducing the on-paper ballistics of the .357 Magnum. Scant amounts of .40S&W, .45 ACP, and a relatively available amount of the obscure and much maligned .357 SIG. And before I forget, I downloaded that link you sent and I’ll read it later today. So, yeah, the 9mm +P velocity is comparable to 357 Sig or Mag but only when comparing it to the most anemic 357 loading you can find. Elmer Keith, an Idahoan gun nut among other things, got it right when he decided to hot-load the .38 Special for use in some of Smith & Wesson’s .38-caliber revolvers built originally for the .44 S&W Special. If bullet diameter, ammo availability and mag capacity were the main deciding points, then why not 9×18 or .380? They advertise 1475fps, for 357sig but it chronos at 1500+ untill you put it in a Glock 33 then it comes in at advertised or slightly under.
