Title: Glock20 convertible to .357Sig?
Post by: Truckdrivingman on October 22 2016 10:07:45 AM MDT
Hello,

there's an aftermarket barrel for the Glock20 in .357Sig. What else is to be changed, when I want to shoot 357sig out of my G20?

Well Lone Wolf was selling several aftermarket options...40S&W / 357Sig / 9x25Dillon / even a 9mm Luger option

I still need to get me a 357Sig barrels for my G20

The barrel's not the problem. I don't think I'll need a new slide. But a new magazine?

No, you use the same magazine.

I have the Lone Wolf version. It runs perfectly in my G20.

Same magazines. Just drop the barrel in and go for it..

The Underwood .357 Sig is a blast to shoot through the G20 with conversion. Pun intended!

Question...
Never  having loaded a necked pistol round... Does the case stretch longer (like with rifles) or shorten like straight walled cases

I don't believe it stretches. But Shadow will be able to answer that question better than I could.

They usually don't grow in length and may get slightly shorter...In all my years I have never trimmed any 10mm cases for reloading...even after many uses.

You will likely lose the casings or they may crack or split with reuse, but care needs to be such that you check the case neck tension due to work hardening with reuse they may not hold their resized dimensions leaving the bullet lose which can yield a bullet setback issue, that can spike pressures.
