Overall the 357 Sig is a good round. Particularly if you have a 40 S&W already.

But, as stated, there are real reasons it is not more widely used.

This has more to do with the gun than with the round. When Glock initially introduced it's guns in 40 S&W and a four years later in 357 Sig they rushed them into production. Glock chose to use the same strength recoil springs in the 40 S&W guns as they did in the 9mm guns (with a slightly heavier slide as I recall). They essentially took a 9mm gun and placed two more powerful rounds in the gun. Both rounds in Glocks developed a reputation for battering themselves. It became a factor in earlier retirement of Glocks from law enforcement use than for their guns in 9mm. That may have changed this, I understand, in the last decade or so. So the durability of the Glocks with 40 S&W and 357 Sig may have been resolved.
Since 357SIG and +P+ 9mm are rated basically the same pressure wise, I would think my 17 would have shown similar wear as my 31. It hasnt, and not anything close. Differences in the pressure curves, cycling impulses maybe? I dont know. I do know my one 17 has a lot more +P+ 9mm through it than my 31 had 357SIG through it though.

Not sure if Glock got things figured out or not, but the 9mm's seem to handle the higher pressure fine, and thats with a stock RSA.

Other than some wear on the anodizing on the frame rails, I never had any real wear issues with my SIG's in the caliber. Those guns also had a lot more rounds through them than my 31.

As far as recoil goes, I really never noticed much if any difference between the two, especially when fired from the same type/model gun. The thing that was more noticeable to me with the 357SIG, was the bark/muzzle blast.

Comparing 125 grain 357SIG out of the 31 and 127 grain +P+ out of the 17, I seriously doubt you could tell which was which if someone handed you one and didnt tell you what it was. The blast would be about the only giveaway.

As far as being "built to handle it", that is a generalization. I remember discussions about .40 S&W being rough on guns back in the day. There was always a question of whether a particular handgun was designed around 9mm and then offered in .40 or if it was really designed for .40 S&W. On an individual basis, some guns are more robust than others. In general though, 9mm +p+ is at the far end of its intended spectrum and .357 Sig is not.

As far as math versus reality, is 100-200 fps a big deal up over 1200 fps? Is there a big difference between 9mm +p+ and .357 Sig on bad guys, game animals, or meat targets? I don't really know.

I'm just a fan of having the right tool for the job. I like 9mm for what it does with normal 9mm ammo in small-to-medium semi-autos. I like .357 Sig for what it does in a full-sized semi-auto with decent recoil mitigation. One is good for around town on a normal day and the other likes to take hikes in the local woods.

Well that would depend on the foot pounds of energy more than velocity althought the two are related, but it's the "foot pounds" that kill though, and the 357 Sig has more ft. lbs. of energy than the 9mm +p+ IIRC.

I was assuming similar mass and shape. That's why I used the 124 and 125 grain bonded jacketed hollowpoints from Underwood in my previous post.

Someone had suggested that the 100-200 fps extra velocity (and correspondingly higher energy) was more notable on paper than in real life. The best way to check that would be to compare them in similar firearms either on well-constructed "meat targets" or via handgun hunting.

Well, it's been a month since this thread was started and I'm glad to see its still generating great discussion. AAAAAAANNNNDD! I have an update.

Just ordered a 229 Enhanced Elite from gunsmidwest.com for $673. $14 shipping and 2.5% on the card. Happy enough with the deal. Was going to hold out for a Legion, but for another $400+, I just didn't see the value in it. Cool pistol, but I don't care if I get a coin in my pistol case. Try to post a pic when it shows up.

I own a couple of 357Sigs and still like the round. However, since I bought my Dan Wesson Valor in 10mm it is an instant favorite of mine, especially with full power loads like Underwood. It has different recoil impulse from my 1911’s in 45ACP. Doesn’t seem as snappy. Really digging this pistol....

Sorry disseminator, .357 Sig was ordered. Plans include a .40 barrel in the near future.

Longshank, you are right up my alley. I'd like to add a nice 10mm to my collection. Look at the Dan Wessons quite a bit every time I'm on the CZ web site. .357 Coonan will find its way home to me eventually as well!

Sweet, you'll love it. I use my 357 SIG mostly for a backup while hunting and stick to 9mm for self defense. It's a great little round.

I have a Glock 20 and MUCH prefer the 357 SIG for anything I'd use the 10 for. The 125 @ 1500 FPS in the SIG is as good as anything the 10mm has to offer IMO. If I need more power than the 357 can deliver, I'll carry my 629. I am thankful I got the 10mm though as it got me started as a re-loader which is very handy when you like to shoot as much as I do.

Just a cpl thoughts on the 357 Sig...A quick review of Sierra's Infinity program shows that a .40 with 135 gr bullets has virtually the same muzzle velocity as the 357 Sig with 125's. I'll say that in my .40's (a Browning HP, a 229 & 226 Sig, and a Colt Cup Elite), Nosler's 135 gr JHP is a top contender for accuracy, feeds 100% of the time & sports a 1350 fps chrono'd muzzle velocity from the 5" Colt. For those reasons alone, I'm not interested in the .357 Sig.

As a reloader I've spent considerable time with a 1920 commercial Luger in .30 Luger. That round, like the .357 Sig has a very short neck and a tendency for bullet setback while feeding. So much so that I bought and use a C-H, canelure tool which helps to some extent, getting a decent crimp on the bullet. I do crimp for the .30 Luger and wonder if the .357 Sig head spaces on the case shoulder or the mouth. It'd make a difference. In that regard, those of you who reload .357 Sig...do you have problems with bullet setback.

Lastly, regarding feeding vs. bullet profile: I've never had problems with any cartridge feeding LSWC's (notorious for feeding problems) of the approximate shape of the old H&G #68 (200 gr. LSWC .45 target bullet). The list includes 125 gr 9mm's, 155 gr .40's, 185 & 200 gr. .45's. It's my experience that with a magazine who's feed lips are not damaged, and with the correct overall cartridge length, feeding becomes a non-issue. Modern JHP's, say designs that have been available for the past 10-15 years or so, should not be a problem in a functioning gun. One of the .357 Sig's selling points was easy feeding with issue ammunition...a stretch I'd say.

But if you like off-beat calibers (and I do), don't mind the expense of the factory ammunition and/or accept the possible challenge of reloading for it, the .357 Sig round might be interesting. It's not on my grail list, however.

YMMV, Rod

Bullet setback is pretty much eliminated by using a compressed load of powder. That, combined with a normal taper crimp will prevent any issue with the 357 SIG. Most of the top loads will end up being compressed anyways, so it's not much of a problem.

The 357 SIG head-spaces on the case mouth just the same as 9mm, 40, 45, etc.

I also shoot and like the 40SW myself, but I don't feel like the 135 grain bullet in the 40 is really the same as the 125 in the SIG at all. Look at the ballistics and the SIG will shoot a lot farther and a lot flatter while better retaining energy and will penetrate much much better than a 135 .40 will at any range.

That being said, I think it's mostly a matter of preference and as an enthusiast I like them all.

I don't flare my case mouth, nor do I crimp. After sizing, I put a light chamfer on the case mouth, just enough to get the bullet started into the case. I've never had any setback issues.
As noted in earlier posts, a slow powder like AA9 will fill the case and prevent setback but for some loads like my 90 gr varmint loads or the longer monolithic copper bullets such as Lehigh Defense XD or XP, I have to use a faster powder like Bullseye. No setback issues even with the faster powders.

Finally, a little gun porn!

She finally showed up today. Bought a box of ammo to get me going. Looking forward to getting familiar with it. Haven't handled a Sig in 15+ years. Feels top heavy, but the one I've ever shot (226 .45) was a dream and very impressed by that one. This is my first Sig always being a CZ fan. Watched a few videos on the Legion series. Looks like a nice gun but it is really all that and a doughnut more than an Elite? To me, it looks like marketing similar to the Harley CVO line. Some nice features but you are really paying for exclusivity?? I'm not seeing real bang for the buck? This one isn't going anywhere, but I'm curious from those in the know. A .40 barrel will be added soon. Appreciate the help here gents!

Diseminator, thanks for the add'l info on the setback and headspace questions. Sounds like you like the round and have no problems loading for it.

My work with the .30 Luger 20+ years ago was interesting to say the least....once I got the crimp/canelure issues solved with jacketed bullets, it turned out to be a tack driver, even with that barley corn front sight and shallow "U" notch rear. The bore ran over 0.310" and I found that it would feed .32 cal 85 grain Hornady's designed for the .32-20 and .32 H&R with ease and give me 1.25 groups at 25 yds. The gun's still in the safe but rarely gets a work out...and then mostly to show some visitors what a "real Luger" looks like and shoots.

Best regards and sorry for the thread drift...Rod

2wheelwander, very nice pistol indeed. No matter what people say, the .357 Sig is a great defensive cartridge, very effective.

Speer’s 125 grain Gold Dot is pretty good ammo to carry in it.

Yelp I have carried a few over the years and yea I own more than one.

Enjoy your pistol, stay safe.

Minor update. Finally got together with my buddy and he relieved himself of ammo he no longer has use for.

1200+ rounds between .357 Sig and .40 LE duty ammo.

.40 229 barrels are on back order with Midway.
.357 dies getting ordered.

Yup, it was worth it to buy this thing and have great friends!!

I am going to be reloading for 357Sig soon, because it is my alt. EDC of XD357.

Same here silvermane. Just snagged a clean used .40 barrel on ebay for $85. .357 dies will be next. Plan on loading up plenty of .357, but will probably shoot the .40 just as much because its so much cheaper.

Still haven't decided if I will EDC this one. Quit a bit bigger than my CZ PCR (love that gun). Until I can shoot a 229 .357 Sig as well as my CZ, it'll be range time only.

That 229 just feels like a chunk to CC. Favorite leather holsters?

Just shot this caliber for the first time, about an hour ago. Put 5 rounds down range. It was not as "snappy" as I thought it would be. Was my friends Sig Sauer, I don't know what model. He was in the lane next to me, he took my Makarov for a spin...Happy Shooting!

I find the 357 to be pretty much the same recoil as .40. But man it seems to shoot so flat it is like a laser! Only a few hundred fps faster but sure seems to be super flat trajectory. I personally don’t see the need for it since I am stocked up on .40, but I can see how it would be a very fun caliber to shoot a lot.

Just snagged a nice used .40 barrel for it on ebay. Midway had Starline brass 100/$24, dies on the way, and some 115 gr projectiles with them. I've got plenty of .40 to run through it while I get some .357 loaded up.

Really looking forward to running both calibers through side by side. I'll get my G22 out and see if its just my getting older or if the .357 round is as pronounced as my hands tell me it is.
