Correct me if I'm wrong, but I'm gathering that perhaps the best mags for 100% reliability are the McCormick 7 round Power Mags, right?
It also sounds like the Wilson 47 (not D) 7 round magazines are also about as reliable as it gets.
What mags does Hilton use for serious use?
It also sounds like the Dan Wesson Valor may be the best choice for a 1911 unless I went with something like a Wilson Combat (but even then, would the Wilson have a better chance of being 100% out of the box?). However, it does seem there's a good chance it will not be 100% reliable out of the box and may need some work, meaning I'd either have to learn to be my own armorer or pay a competent 1911 gunsmith to do so, which seems unlikely as all the best ones are either not taking work or are years backlogged.
