I have been running wilson 8 round mags for a few years now, and i swear by them. As for a good quick holster take a look at the serpa holsters by blackhawk or the safariland ALS holster. It gives you the right amount of speed to retention ratio. Just my opinion.
finally got the call and am going tomorrow morning to get my pistol permit. Gonna get the 1911 this weekend im so excited about it haha. I was looking at the serpa holsters tonight at cabelas it looks like a well built holster there price was 47.99 for the carbon fiber one. I picked up some corbon 230gr JHP 45auto +p to try also!
