Doing some research I found that the .357 Cal XD can shoot .40 with no issue. All that needs to be done is swapping in a .40 barrel. They also say .40 mags into a .357 work without issue.

Can anyone verify this?

This works with Glock as well. 40 cal mags will hold 357 and vice versa. All one needs to do is swap the barrel out. The 357 sig is actually a 40 cal shell crimped to fit a 9mm projectile.
Exactly as I remembered it. Just didnt know if there were adverse effects.

Now to find a .357 XD :D

I've owned 2 357 sig Glocks, one was the 32 the other a 33. Great caliber there's no doubt about that but the sound that it makes its ear popping. Believe me, even with ear plugs in, you're bound to go deaf just shooting that thing too much. If you ever had to use the 357 sig in self defense you would probably suffer irreversible ear damage, as would everyone around you. I myself have opted for the 45 because no matter what round of sig you are using, it is most likely to penetrate through a person and hit someone else as well.
Very good point and I do agree to some extent.

However..If I was using it in self defense, I would rather walk away with slight hearing impairment versus my life. The other thing I was thinking, if I decided to carry .40 for self defense, load some corbons in .40cal and swap the barrel, problem solved.

First off I'd just like to say that you had a very good post. I would like to add one thing to support your point on pressure. Part of the reason for the higher psi is the slope of the shoulder after being necked down from the .40 casing. It makes for more space for the gasses to bottle neck.
Secondly I would like to echo your comments on the extra stress on the firearm itself. Very well said.
Thanks for the info guys. Ive also heard of the added pressure, but with routine maintenance wouldnt that prevent any critical failure? My plan is to shoot .357 sig on a regular basis to train, but .40 when I am sport shooting and just having a good time.

I called up two guys in Oregon who I know have .357 sig. Once is actually an officer who puts atleast 200 rounds a week through it. He said he has never had any issues at all.

Which caliber are you going to CCW with? If it is the it is the .357sig then yes train with it. I believe the XD is strong enough to take it. It is well made and strong and if you bought the .357 to start with then it was meant for that caliber from the factory.
I would like to carry .357.
