.357 Sig vs .40 S&W

This is a discussion on .357 Sig vs .40 S&W within the SIG Sauer Pistols forums, part of the SIG Sauer Forum category; I have a SP 2022 chambered in .40 S&W and was wondering if I could use a .357 Sig barrel. Thanks....

I have a lot of .40 cal handguns, and I have a few .357 SIG barrels for a couple of them. It's kind of a fun round to shoot, and on the 229 and 226 at least, there's not a lot of difference in recoil. However, .357 SIG ammo is too expensive to shoot often, so I generally don't use them much. If you're seriously considering using .357 rounds as a defensive round I'd say give it a try, but to me, there's not enough difference in performance between the two rounds to justify the extra cost of .357 rounds.

What I would do is try to borrow someone else's .357 SIG handgun and shoot it first before I dropped a couple hundred dollars on an extra barrel for what is already a great hangun.

JMC24, If you get that .357SIG barrel, I can almost guarantee you will put the .40 barrel back in the case. The ammo may be more expensive, but so is the WOW factor. If you shop around, reasonable .357 ammo can be found.

The Sig .357 does better in the ballistic tests that I have reviewed than the .40, 10mm and .45. The Secret Service and Air Marshals have gone to the round and so have a couple of State Police Departments.

I have .357 barrels for my P226 and P229. I usually have one of .357 barrels in either gun so I can grab it for the homestead battle.

Shop around for deals on the barrel. Likely you will like the round performance but be a lil peeved by the price of ammo.

I picked up a P229R in .40 than I picked up the 357 bbl and love it. If you convert to the 357 you can swap back to .40 for most of your shooting and save over shooting the more expensive 357. Then shoot the 357 when you can. It wont take long before you find yourself looking for and finding deals on 357 ammo to shoot it more often.

357 sig is a great round. As bombboy said there are several federal agencys that have adopted the round. It will be around for a while. Its one of the rounds i reload. Once you get it down its not a bad round to reload. Its very accurate, i have 2 p229s and a baby glock in that round. The all shoot very well. I am also building a 1911 in that caliber.

I will. I found a kimber custom combat with severe pitting on the slide. I picked it up $400. I also bought a 357 sig barrel from fusion. So far
