Glock Conversion ?

[matai]

Hey I want to get both .357SIG and .40S&W conversion barrels for my Glock 20.

What mags should I get?

Thanks

You use stock G20 mags for 40/357 conversion:

That's awesome, do you guys have any experience with these?

I installed I think the 24lb spring in my Glock, do you think I'll have to swap that out to shoot 40 and 357?

Edit, that could be a 22lb ISMI spring...
