Yes, went over that in detail with Glock support. The tech said I could consider getting better quality screws then the ones provided by Glock. He said they were rated at around 100,000 psi tensile strength and should be fine under most circumstances, but he said McMaster sold some that were rated at 140,000 psi. I tried to look them up, I wasn’t sure I found the right ones, and did want to pay $7 each for them.
then, I found them for $2 at Big Tex Ordnance. I never heard of them before, but took a chance since it was just a few bucks.
