357 sig or 10mm auto

Best of both

Hello there. I am interested in getting some opinions here. I want to get started Shooting some bigger bore handguns. So far I have only used 9mm handguns.

I want to get either a glock 20 in 10mm Auto or a glock 32 in 357 sig.

I will use it for target/fun Shooting and also as a short range self defense gun.

I am no reloader yet so I have to stick the factory ammo. Here in Austria the supply of ammo fort both caliber is quite difficult, but I am willing to deal with it.

I know that the smaller companies offer nice 10mm Auto rounds, but how about the 10mm offerings of the big ammo companies, like Federal, Winchester and Hornady? Are they close to the orginal ballistics of the 10mm Auto or are they watered down?

If I get a 10mm Auto I want to use the full pontential of the round and not the watered down Version. in that case I could get the 40 s&w and not the 10mm Auto.

In 357 sig the Situation seems to be a bit better. The Standard offerings in that caliber look promising judging the ballistic data.

What do you guys think about the 10mm offerings from the Main ammo companies? Are they any good ?

thanks for your help in advance

greetings from Austria

I Have a S&W MP 40 and have a KLM barrel in .357 Sig ,uses same Mag give the performance of two high power calibers in one gun
 
I have had a 1006 for 20 years and recently bought a Ruger SR 1911 in 10mm. I have been pleasantly surprised. The Ruger has run everything that I have bought or handloaded for it. It has very manageable recoil and is as accurate at 25 yards as any of my 1911 .45's. I am shooting 2" groups at 25 yards with a 180 grain Gold Dot loaded to a full house load.
 
I would go for the 357 Sig because with a barrel change you can switch to 40s&w and still use the same magazines/slide/extractor.

And you can still go back down to 9mm by swapping out the barrel and magazine. The pistol will safely function with the stock slide however you may or may not get 100% reliable extraction. But it will work.

Can't do that with the 10mm.

10mm nut's view

I can probably say with a fair degree of certainty that I'm one of the nuttiest, if not the nuttiest, 10mm nut on the list. So take what I say with that 10mm grain of salt.

I was one of those "40 Short and Weak" guys who poo pooed the new caliber as very much less than 10mm. I now have 3 or 4 40 S&W in the accumulation as age softened me and had me relenting.

10mm is a great round for a reloader as you can roll yer own high-powered loads to suit your launcher's idiosyncrasies. S&W 10mm launchers are wonderful in both semi-auto and revolver. Factory ammo is mild but there are some decent offerings out there.

I'd rather carry/use/abuse a G20 or G29 as replacement is just a purchase away. Doesn't mean I don't need my 1006/1066/1076/1026/1086 collection members - it means that pragmatism dictates using items that are easily replaceable should the need arise.

But if it came down to choosing between the two, I like the strategy recommended in other replies of a G20 with an extra .357 Sig barrel.

I have seen some excellent pricing on G32 and if someone offered me one for a song and dance, I'd prolly end up in the .357 Sig camp too. But I'd steer clear of reloading due to necked case being a pain in the rear.

Clear as mud?:D
 
Thanks a lot for the further replies. You guys have convinced me. I will get either a glock or another gun in 10mm with an extra Barrel for the 357 sig. So I can use both caliber in one pistol which is awesome.

Did a bit Research about the ammo Situation too and it is interresting. All in all the ammo supply in 10mm Auto is better. you can get either FMJ or TFMJ for target/fun Shooting and for self defense I could get the 180 grain hornady xtp? What do you guys think about that load?

On the other Hand for the 357 sig I could just find lots of FMJ ammo which is great for use at the range but not so good for home defense situations.

So it seems according to the ammo supply the 10mm is more versatile.
 
I like the 155-165s for personal defense, target work and small to medium game hunting. Then skip up to the 200 hardcast for medium to large game and woods defense...

..but anything works...Bob
 
A note on the 10mm 180 gr load.

I watched a Gel test with the hotter Underwood 180 JHP Gold Dot
shot out of the Glock 20 with a 4.6" barrel.
The box had 1300fps as a fps and the G20 produced 1328fps.

The bullet penetrated almost 18" and was just plain UGLY.
It looked like a train wreck and even had some Separation !!

The tester did a second test with just water jugs, so to test just the fps.
This test showed maximum jacket fold back and also bullet separation starting.
30% of the bullet was lost, due to fragmentation, going through three jugs!!

It will do the job but the tester has NEVER seen the Gold Dot ever separate in any of his other bullet test.
A first.
Maybe 1300fps is just a little to HOT for the Gold Dot design at this short distance.
The good news is that this load comes at 1250fps or slower by many companies.

Just a heads up.
 
Thanks for the warning Neveda Ed but a far as I know the underwood rounds are very hot rounds. Hotter than the 180 grains rounds from other companies. So the risk that the Standard rounds will fail is not that high.

here in Europe we can just get the rounds from the bigger Ammo companies. The smaller ammo makes with their hot rounds, like Corbon, underwood, doubletap and many more do not sell their stuff in Europe unfortunately.

I would be interested in their stuff if I could get it.
 
ROCK OUT WITH YOUR GLOCK OUT?

IF you really want BIG BORE, America's tried & true sweat heart the 45acp would be my pick. In a semi auto it is pleasant to shoot, more so than a 40 cal IMO, can deliver a fast follow up shot, comes in heavy weight bullets. I've never fired a 357 SIG, but the "idea" of a bottle necked case feeding better in a semi has it's appeal. The only 10mm I've fired was in a full sized stainless S&W revolver so IDK how the recoil might be in a semi auto, or if mag capacity is an issue for you.

Thanks for the advice. Well the good old 45 apc was not on my list in the first place but after checking the ammo availability of the 357 sig and the 10mm Auto again and again, getting a .45 would be very tempting. With the Standard .45 I cannot get in Magnum territory in the semi Auto pistol realm, which was the reason why I got intersted in the 357 sig or the 10mm Auto in the first place. But the 45 apc would have many benefits. for sure. Ammo is quite cheap and easily available.

I can get man FMJ rounds for target Shooting and even some decent self defense rounds like the Gold dot, and also some classic jhp rounds from Remington at a good Price.

If i get a .45 pistol that can be adjusted to use 45 super rounds I can still get in the Magnum realm in the future if i start learning reloading.

The HK line of full size USP pistols do not need any adjustments to safely operate with 45 Super ammunition.

It does not matter if you choose one of the duty guns or prefer the target guns like the USP Expert and USP Elite. They will even work fine in the suppressor ready USP Tactical

Just load the magazine and you are good to go

The USP Elite is nice for the 45 SUPER since with the Elite's 6.02" barrel you get a little extra velocity and energy

I know it kind of looks like a giant Walther PP, but it shoots great
 
I have a glock 35. It is a 40 cal and glock calls it a competition model or some such thing, longer slide, better trigger , adjustable sites. I have 357 sig and 9 X 19 barrels for it. I only change the barrel, not the extractor , the springs or even the magazines. I haven't shot the 357 Sig much but it functioned fine. Same with the thousands of rounds of 9mm, that is with the 40 cal mags. With the Sig barrel it is my favorite woods - great plains carry pistol.
 
I like both calibers in question but I belive the 10mm is a superior round. It seems that the .357 Sig was designed for one main purpose - to duplicate the popular and effective 125 grain@1400+fps .357 Magnum load in 9mm sized autos. The .357 Sig achieves this goal quite well. Of course, light loads of 9mm +P+ and .40 S&W can come close to that velocity as well.

However, the 10mm is a different animal. When fully loaded, the 10mm can put a heavy bullet down range with a very high velocity, even out performing the .357 Magnum. But whereas the .357 Sig does one job well, the 10mm can do several jobs. If one needs a good hunting or outdoors gun, a 10mm loaded with full power 180 or 200 grain bullets can do the job. On the other end of the spectrum, full power light bullets can be had with very high velocity too. Also, lighter 10mm loads can be had, much like shooting .38 or .44 Special out of a Magnum. I find the 10mm Hydra-Shok to be an excellant defensive load for my Glock 20.

The 45 Super case is beefed up, so don't use standard 45s or even 45+p.

I love my 10mms and 357 sig. Having wrote that, I took my full size HK USP 45 and installed an 18# recoil spring, +5% magazine spring and shoot 450 smc. It's the same as a 45 Super but with a small magnum rifle primer. Edit:I also installed a 6" barrel in it. It's not the Elite barrel. The o-ring grove is cut for the full size usp. It's an HK factory barrel and is almost half the cost of the Elite spare barrel.

Thanks a lot for the advice concering he HK USP Line. I will take a look at them and chose a good model.

@CCantu357 I agree. With the right loads the 357 sig and especially the 10mm is a very interesting and versatile round. Unfortunately the best loads are not available here in Austria. As long as I am not a reloader It is not practicable to get these rounds.

45 apc rounds are easier to get. Decent fmj rounds for plinking and some 230 grain hydra shok rounds are cheap and easy to get.

I assume the hydra shok rounds are very sound bullet design for sd. maybe a bit old fashioned but still very effectiv. Or what you guys think about the hydra shok?

Thats why i go with the .45.apc to start my big bore handgun joruney and when I am able to reload I get the magnum root with the 45 super.
