Thinking about getting a Glock 21 Gen 4. Without regard to whether the boolit is cast or jacketed, does the Glock 21 Gen 4 factory barrel deform or have a tendency to deform 45 ACP brass (i.e. cause a Glock Smile) or otherwise weaken the brass because of lack of case support provided by the factory barrel chamber.
I use a G22 and G30 both with LW barrels. I use only range pick-up brass and see a Glock Smile on maybe 1% of the 40 SW brass I collect and it goes in the trash. I check all 40 SW brass after it's resized and cleaned with a chamber gauge and maybe 5% needs to be run thru the bulge buster for a plunk fit.
I have buckets of sized and cleaned 45 ACP brass and have never seen a Glock Smile or any obvious deformation on any of it. Maybe I wrong but a lot of it is bound to have been fired thru Glock factory barrels.
I'n not worried about shooting cast in a Glock 21 Gen 4 factory barrel but I am worried about what an other than fully supported chamber might be doing to the brass.
Thanks for the input.
