I am asking a question on behalf of a friend of Mine that works at the pistol parlour here in Arizona. He wanted Me to see if anyone has experienced, either first hand or second, frame damage or any other damage to the glock 20 or 29 from a steady diet of the higher powered 10mm rds. I told him that, although I have the 2 guns, they have only digested factory loads Ie... American Eagle. My natural instinct would be to think that the glock 10mm's would be some of the most stout weapons at handling the higher output 10mm rds. Thank You for all of Your help!
