I have acquired 2 of the fancy new Black Wilson HD ETM "super mags" with metal followers. Not really sure what the fuss is all about. My brother splurged on them because he lost his 1911 mags during a move. They would not lock into his gun! Since he ordered them online and return would be a hassle, I just handed him 4 of the newest magazines in my pile and tossed his in my bag. Both mags loaded and fired fine in the gun I happened to have in the bag.
Just stick with the good ol Wilson ETMs for an 8 round mag and keep fresh springs and followers in them. If your gun doesn't have a magwell you might consider swapping out the base pads.
Funny you mention that, I did snag a magwell just have to install it!
Cool wilson mags are slick! I haven't had any problems yet, even with the factory colt mags! I had forgotten how much I loved running a 1911, wow! That magwell should make mag changes quicker too.
Hamfisted Geezer with your beer can reloads. I true operator doesn't need a magwell. That is why Glocks don't have those.
