Thanks for your replies, SLG. I'll be ordering some Wilson mags as well now.
I guess there's only one way to find out. Poor me, having yet another excuse for more range time. I just can't catch a break .
Fantastic, thank you.The Hill Brothers, Hillpeoplegear.com both carry lightweight SA 1911's. They have not shot 42,400 rds through them (I'm pretty sure they haven't), but they are pretty dialed in on what the LW frames need and can take. They have a forum on their site which discusses at least some of it, I think. Might be worth reading.
