I have one of the original Delta Elites and I have no complaints after multiple thousands of rounds of full power 10mm. Have a Glock G20 also and have no complaints. I don't rteload 1omm but I use a substantial amount of Win 175g Silvertips and Prvi Partisan 180 hp. Hot stuff No probs.
Saw a guy 2 stands down from me shooting the Win 175 gr Silvertips today. He wasn't having a problem, either..
