.357 SIG powder and bullets recommendations

Case gauges are essential in reloading if you wanna avoid problems with chambering the rounds properly, especially with such a high pressure pistol cartridge like the SIG. Make sure you get the crimp right to avoid setback. I made a few dummy rounds first and chambered them a few times and measured the set back til I got it where it needed to be.

Question on using the 40 S&W sizing die? If I use it and then use the 357 sizing die to set the shoulder I won't need to lube right?

Yes that is correct. Size the body with the 40 carbide, then set the shoulder with the SIG die. It keeps you from having to lube then clean the brass after sizing.

Perfect. Thanks again

Any time. Good luck, and enjoy! The SIG is fun to shoot. Keep in mind, you may want to go with a slightly heavier recoil spring if you use full power loads. The XDm comes with an 18# spring from the factory which works well with factory loads and light plinking loads. But with full power .40 and .357 SIG loads, I ended up going up to a 20# and it smoothed it out a good bit. I have a 22# I will be trying soon to see if it makes it smoother or if it is too much.

I'm wondering how it will be for the Glock 32? This is what I'll be shooting.

Recoil springs are cheap, usually around $7-$8 a piece. If it is a Glock, most dealers carry springs for them, at least in my area. I'm not familiar with the Glock, but it should do just fine. If it was a .40 and the factory spring is still in great shape, you should be good to go. My factory spring was fine, but the heavier one smoothed out the snappiness of the full power loads that are running 1,480 fps - 1,500 fps.
