I'm intrigued with this cartiridge and it will probably end up being my next handgun round. I have a few questions.

I know some guns originally chambered in .40 can be converted with just a barrel switch. Is the opposite true? Can a gun designed to handle the
.357 sig also function well with a barrel swop and .40 ammo?

Are there +P or +P+ loads sold from the factory to get closer to true .357 mag performance?

What is your overall oppinion of the caliber in terms of popularity long term? Will it become more popular over time or less?

If you have any compaints with yours, what are they. (Besides cost of ammo)

What's great about it to you?

I just love the idea of .357 like performance in an auto and always feel that it is better to be over gunned than under. I want a round that would be sufficient in just about any situation and this seems like a winner to me. Thanks for your comments
 
Yes you can convert a .357sig into a forty cal with a barrel swap.

It will be around for a while, not as popular as a 9mm, 40cal or 45acp, but a little better then the 10mm and 44mag.

I have a sig 229 in .357sig and think it's a great gun, one of my favorites.
 
I love my G31 in 357 Sig. The cartridge is very fun to shoot and it is very loud. Definitely turns heads at the range.

Typical velocities for the 115~125 grain 357 sig round are about 1400 fps per second( though a lot of rounds are loaded signifigantly slower:() There are .40 rounds that put a 135 grain bullet into the same fps range, which I think may be a deal killer for some shooters thinking about buying into the 357 sig.

If you want to get into the 357 sig you really have to be in the camp that the smaller caliber bullet will do what you want it to do more than the larger caliber of the 40.

With the .357 sig you pretty much have the option of 115-125 grain bullet, where as with the 40 you can get up into the 180s.

If you really like the 357 sig, buy a gun chambered for it and buy an aftermarket 40 cal barrel for cheaper shooting at the range. If you buy a pistol in .40 first, then it is not necessary to buy a barrel in 357 sig because you can buy .40 rounds that will do pretty much the same thing.
 
Another plus of the .357 sig is the bottle neck cartridge feeds VERY well, almost impossible to have a jam from a misfeed.

I'm almost positive there aren't any +p rounds. The 357 sig is already a very high pressure round with a chamber pressure of 40,000 psi.
 
G32

Very pleased the G32 I have; primary carry and HD. Great size, good weight, very portable. No FTFs, FTEs so far: ~1K rounds. Lots of fun, too. :D Good luck.

As far as cost, if you by in bulk, the .40 S&W and 357SIG are basically the same price. Its a couple of bucks a box more than 9mm, and a couple of bucks a box cheaper than .45ACP.

Self Defense type performance ammo is basically the same price as the others, including 9mm.
 
jackslayer, I'm in the same boat as you. I have a possible lead on some lightly used G31s. I've been intrigued by this round since its inception. It has been adopted by quite a few states' highway patrol agencies, so I think it will have some marketplace staying power.

About the caliber swap, would it be possible to drop a G22 barrel into a G31, or would one have to get an aftermarket barrel specifically made for that purpose?
