Hi guys, hope you're all doing fine. I a have question regarding the g31. My brother wants to purchase a glock for use as his service firearm, he's first choice is a g22 but is also interested in the g31. I opted for the g31 pointing out that he buy a barsto aftermarket .40 barrel for practice purposes (and to limit the possibility of a KBoom) and use the .357 sig barrel for carry. My question is, was my recommendation a good option ? Or he should just buy a g22. Are the newest g22s have full support barrels already? Thanks.
