My MC Operator and CMC Mags don't like each other.

Back in the mid to late nineties..I had 3-4 Shooting star, McCormick whatever the hell you call them mags, and still to this day they were the most unreliable magazines ive ever run in any weapon. Got so mad one day I threw them on the ground and stomped hell out of them, Id had enough of that non-sense. No more for me...EVER.

Aren't the Shooting Star mags CMC's budget option?

That's funny. CMCs have weak springs so you use Wilsons instead.

I'm no fan of Devel followers, but a CMC tube is GTG. If the gun runs correctly, it will work fine with CMCs, Wilsons, or any other decent mag.

The SA's don't seem to like the devel follower.

I don't favor WC springs over CMC springs.

I think there's something wierd going on with some Springfield slide stops.

Maybe.

I use CMCs in my Colts.

Wilson nylon and split dimpled follower in SA's and haven't had issues.

I have a Springfield Lightweight Operator that runs fine with the CMC 10 rounders and the Wilson Combat 8/10 rounders. I bought it used and as far as I know, nothing has been done to it.

My info probably doesn't help what so ever.

I had the same problem with my Springfield LW Champion Operator and CMC magazines.
The problem was the slide stop notch was dragging on the inside of the frame enough to hold down the flat sheet followers like the CMC.
It did not stop Wilson followers or the Tripp/Checkmate style followers.
A few swiped of the file to open up the notch a little foxed the issue, but I went ahead and replaced the slide stop with a 10-8 slide stop.

I don't have any issues with slide stop movement; mine moves freely without any sort of dragging or binding.

As mentioned in the OP, my issue was the CMC followers jumping over the slide stop itself.

I recently dumped my cmc power mag and power mag+ followers for the all steel tripp followers. Like it's been mentioned and most of you know, the follower on the cmc mags has to jump forward enough to engage the slide stop. I found the followers in my mags wouldn't do this reliably enough for me to trust them. Even with the mags super clean, still unreliable. My 1911 is a NM mil-spec built up by SACS. I used quality parts throughout, including an EGW oversized ss. I was originally thinking that the ss lobe might be outta spec, but the gun runs all other mags just fine, from el cheapos to the now upgraded cmc/tripp combo. Oh, the tripp upgrade turned my 8 round mags into 7 rounders. The nice guy at tripp research said I might could get 8 again if I try trimming the springs. I'm not too worried about that right now though.

Funny, I've never had an issue with CMC mags not even the cheap ones.
