Has anyone done this with a sub compact? If so how do you like it? I'm looking at the EFK conversion and would like some more info before springing for a new barrel.

To the best of my knowledge, no one makes a subcompact .357 barrel.

Here's one right here.

Considering that a Sig .357 is just a necked down .40 there should be no issues at all. Now with that being said have you priced .357 Sig ammo lately????? YIKES!!

Well Ill be danged! People asked for one of these for a long time and thats the first I saw one. Good fine, now I wonder if the .40 would be the better choice due to ammo cost and in the 3", I dont know that there will be enough increase in velocity to make the .357 perform the way it does in the 4-5 inch barrels.

Soemthing to definately think about though.

I'm with you on the performance. Generaly if you are using a SC you're doing personal work at very close range... and now the added velocity of the .357 vs. the bigger hole of the .40 debate can now start.

I belive most of the experts say that most CCW encounters will happen within 21 feet.

I think I would rather have a XD-9SC than an XD-357SC. I do not believe that in a short barrel like the SubCompact that the 357Sig has that much velocity than 9mm +P loaded with the same bullet. With a barrel that short you can only burn so much powder before the bullet leaves the barrel. The rest just burns out there as muzzle flash. The 357Sig is a great cartridge but its advantage start to fad over 9mm +P as the barrel gets shorter.
