I’ve been waiting for this to happen for some time and now SIG has come out with a 1911 in .357 SIG. This puts near .357 mag performance in the Tacops version of the SIG 1911.

The Tacops is a SIG 1911 I have a lot of experience with having owned one for several years. They picked a good model to start off with the .357 SIG caliber. Details on the Tacops is listed below.

From SIG Sauer:

NEWINGTON, N.H. (September 21, 2015) — SIG SAUER, Inc., is now shipping its proven 1911 TACOPS platform chambered in the powerful .357 SIG caliber.

With a tried and tested pedigree earned working with law enforcement agencies such as the Texas Department of Public Safety, the SIG SAUER® 1911 TACOPS offers top-of-the-line accuracy and reliability in the ergonomically friendly 1911 design. Now paired with the high-velocity ballistics of the .357SIG cartridge, the 1911 TACOPS is the perfect choice for personal defense or small game hunting.

The Nitron® stainless steel slide and frame boasts a rugged, durable finish, while the Ergo® XT grips provide a firm command of the pistol even when wet or muddy. A skeletonized hammer and trigger offer high performance while the crisp, 5-lb, single-action-only trigger maximizes the accuracy. The 5˝ barrel capitalizes on the enhanced ballistics of the .357SIG cartridge, and ambidextrous manual safeties provide the flexibility demanded by professional users.

Low-profile night sights and a MILSTD dust cover rail for lights and lasers make the 1911 TACOPS a great low-light option. No matter if the task is concealed carry, law enforcement detail, or hunting feral hogs, the 1911 TACOPS is up to the challenge.

The 1911 TACOPS package is rounded out with an enhanced beavertail safety, steel magwell and four
8-round magazines.

With ballistics matching the vaunted .357 Magnum round, the .357SIG features enhanced energy transfer and intermediate barrier penetration capabilities. In use by numerous elite law enforcement agencies, the .357SIG is ideal for defensive duty.

    MY 400 Corbon shoots the factory 165 grain loads to 1,361 fps which is about 650 fpe. The 400 Corbon just requires a replacement barrel and stronger spring in a 1911. Just run a 45 acp case thru the die and walla, a 400 Corbon case. Don't know why it did not catch on as a dozen companies offered conversion barrels for Glocks, Rugers, and 1911s. That being said, it approaches he 10mm and is probably just too much recoil that most people can handle...FWIW (the 400 is just 45 acp necked to 40)

    One thing I have not heard mentioned is the benefit of the bottle neck case. I own several 1911s in 38 super, 45 acp and 400 Corbon and never recall a jam of any type. However, I have owned brand name 1911s in 45 acp that simply were not reliable with some hollow point ammo. I carried 1911s in 45 acp for military, local and federal law enforcement and it was a big deal when that large hollowpoint stops the gun at the feed ramp. That is not a problem with bottle neck cases like the 357 Sig and 400 Corbon. I would carry a 1911 357 Sig in law enforcement and never have a concern at is superior to my 38 Super which I like a lot.......FWIW
