I've bought two NIB 45ACP MilSpecs and they both came with just one mag. Gotta keep prices down, I suppose. I sold the first MilSpec to someone that just 'had to have it.' I still have the one unused mag that came with my most recent one. I have five 7 round Wilsons, five McCormick 8 round PowerMags and five MetalForms (from MetalForm) 7 rounders with rounded followers and have had two failures out of any of them. Very pleased.
With magazines, keep looking on this forum, on 1911forum.com and on eBay and you're bound to come across great deals from time to time. I haven't paid over $20 shipped for any of these 15 magazines.
