So, I purchased just a straight forward 1911 the other day, and decided it needed some spare mags. Every where was out of stock, and eager to get going, I didn't want to wait for them to get more in. What I did instead is found a website that sold 1911 and mags and purchased a couple. They are on their way and I'm excited to receive them but while reading some stuff on the internet, I read that MEU mags cannot be used in a regular old 1911, is this true? If so I totally just spent $100+ on unusable mags. In the photos they look identical but I read that they valve is slightly different. Please tell me this is a nightmare!
