Glock 20 conversions

[rbernie]

For those of y'all who've used a conversion barrel in your Glock 20 (40S&W or 357 Sig), what did you do for magazines? Can you use the 10mm magazines without issue, given the shorter OAL of the conversion rounds?

I use the stock mags in 357 with no problems.

I don‘t have a G20, but I do have a G29 with three conversion barrels, and the same mags work great with all of them, 357sig,40S&W, and 9x25dillon, there are a few guys out there that put plastic spacer in their mags in the rear to push the case‘s forward a bit but I never seen a need .

My 10mm mags work great in my G20 with it's 40 S&W conversion barrel. I use it in the local action shoots and can't remember ever having a feeding problem with my gun.
