    Chip McCormick mags in an aluminum frame...

    Hope this is in the right place, I tried the search feature & didn't come up with any help.

    I just heard something about it being bad to use Chip McCormick mags in an aluminum frame 1911.
    Could somebody please expand upon this?

    TIA,

    The CMC 1911 mags use a steel follower AND that followers pointed leading edge can on _some_ guns contact the feed ramp.
    Steel being harder than aluminum can result in surface damage/irregularity to the feed ramp.

    Myself I have been running CMC mags for a decade, carry and competition.
    They work!

    Across that time I've been using them among two aluminum lower 1911s, a Colt up to current and an SA that I no longer have.
    No feed ramp wear nor function issue with those magazines at all.

    Further the OEM Colt magazine is of exact same design with a steel follower.
    While NOVAK/ACT mags (OEM from Sig) use a folded leading edge with no possibility to contact any guns feed ramp.
    I also use Wilson magazines and they have a plastic follower.

    Edit:
    I figured a pic would do better than me using words...

    I run these in both 8 rd. and 10 rd. for IDPA as well as carry.

    Thanks.....it is my understanding that the "new" Power Mags "Plus" are OK to use in aluminum frames, but not the old Power Mags like in your picture.

    I recently bought some & don't recall if mine were the "plus" version....I need to check when i get home.

    The problem occurred several years ago with CMC's cheaper Shooting Star mags. The follower could actually follow the last round forward past the body of the mag and strike the feed ramp. I've never heard of the issue with their Power or Match Grade mags.

    Yep all I have ever used are CMC 'Power' mags.
    My oldest is nearly a decade old and the newest (ten rounders) are like 3 or 4 yrs. old.

    No problems. No damage.
    And both the Colt and SA had/have been back to the mfr. for other repair work with no comment toward feed ramp damage/wear.

    From their website for the Power Mag Plus: ALL NEW FOR 2010! New follower design is 100% aluminum frame safe!

    They don't state that for the regular Power Mag.
