I have an opportunity to buy a Sig "Tac Ops" 1911 in .357 Sig.
Wanting to know how durable this gun should be with this round?
Thank you-

I'd think it would be as durable as any other gun chambered in .357 SIG and probably more durable than many.

On the other hand, there aren't a whole bunch of 1911's chambered in .357 SIG or even .40 S&W. The round is shorter than rounds like .45 Auto and .38 Super that the gun was designed for, and the 1911 folks are just now getting the 9mm reliability up to where it needs to be. Reliability with the .357 SIG would be my bigger concern. Magazine options will also be limited, though all you really have to do is find one style that works.
 
Anything designed for 40 S&W will handle 357 Sig. since it is a Sig product, I would trust it more than any other 1911 in that chambering....,of which it is most likely exclusive to Sig.

Unless you really fall in love with the cartridge, I see this gun being sent down the line. It can be hard to sell 357 Sig chambered pistols but even more so in a non traditional for the platform chambering.

BTDT with 357 Sig recently.
 
I have a Sig M1911 chambered in 357 Sig and it has been 100% reliable but I only have a couple hundred rounds through it.
 
SIG doesn’t make any junk. From a practical point of view, I believe that pistol will outlast you! If you set out to perform a torture test on that pistol, ie. rapid fire with 20,000 rounds available, no cleaning and only periodic maintenance, like lube on the slide rails, I’m sure you would start to see some throat erosion in the barrel at some point. You would probably find yourself replacing the extractor, which has been somewhat common with people torture testing 1911 pistols in 45 ACP around the 10,000 round mark on some occasions. Actually it would be an interesting study. Considering the cost of ammo, expensive too. SIG may have some ideas on this subject. I’m sure they have torture tested their pistols. The trick would be in getting them to fess up.

Some years ago, I called Ruger and asked what the service life of the GP100 was. The guy told me that they didn’t know because they had never worn one out...this was a bit of a tongue and cheek reply I’m sure. Then he went on to say that at some point they would expect to have to replace the hand and cylinder stop but that was about it. Given the robust design of the GP100 and the SIG 1911, with the exception of the parts referred to above, I feel fairly confident in saying that with a little basic maintenance, these handguns will last you a lifetime.

Note SIG uses an external extractor for their 1911's, which probably work just fine, but it is an uncommon arrangement for a 1911. Combined with the unusual .357 SIG/.40S&W chambering, SIG may be the only source for those extractors.
 
Based on the quality of the Sig pistols I have, including a 1911, I would buy with confidence.

So does Smith & Wesson. I’m sure that external extractors are more easily fit to a pistol than the internal 1911 extractor where proper tensioning is a must. Whether internal or external, that’s one relatively small part that gets quite a bit of wear and is likely to require some attention faster than most, if not all, of the other small parts. The whole proposition is a pretty minor thing and only takes a few minutes to address.

There are other 1911's that use an external extractor, but my point was they aren't common and the external extractor S&W uses in their 1911 is not the same as the external extractor SIG uses in their 1911's, whereas the 1911 internal extractor is a fairly common, user installed part. The external extractor combined with the unusual chambering, may make sourcing such a part more difficult in the future.

For example, what would you suspect is the availability of an extractor for a SIG P220 in .38 Super?
 
Given the cost of 357 Sig ammo, buying enough ammo to wear it out would cost much more than the gun did.

Agree

Speer Lawman "Seconds" are $10.99 a box at my LGS so it's not 9mm cheap to shoot but it's not ridiculous.

That is a good deal.
357 Sig is loud.
Recoil is similar to 40 but IMO 357 Sig muzzle flip may be a little less.
125 HST and Gold Dots average 1,350 fps or so out of my Glock 32.
