I haven't turned up any suppressed HP .45's in my searches yet.
Yes, but he still removed slide material, in the same location you will be, for the bushing and threading. If he wasn't confidant that the slide could handle the stress, he would have said so. Probably wouldn't have sold it either if he thought it would grenade.
