I like stock Glocks and have passed handgun qualification in 3 calibers, with stock Glocks, two of which weren't mine. My G26 with a G19 magazine and sleeve; my G23, which lost a sight, and was replaced with a range rental; and a rented G30.
The quality and interchangeability are pillars of support to LE Armorers.
They don't support many customized 1911s.
But, I was looking for 10mm conversion barrels today, for my new G30, and I can't find any.
When I converted a G23 to 9mm LW Barrel it worked fine with 9mm mags and no other changes. I don't know how easy the 45 to 10mm conversion is, ...but if I can't get one...
