I have put tens of thousands of rounds through McCormick 8 round magazines over the years with no issues. But they would contact the ejector on a couple of pistols and although I have relieved many ejectors to avoid contact with magazine bodies these two pistols had too much ejector contact for me to be comfortable removing metal from them. So, i began to look at other magazines in a quest to find one that would solve this particular problem with these two pistols.

I tried the Tripp 8 rounders and the Check-Mate extended tube 8 rounders. Eureka! I love the Tripps. I love the Check-Mates. The Check-Mates are different in that they use hybrid feed lips which allow for very smooth feeding and they have the little "pimple" on top of the follower to help prevent inertia feeds plus they're less expensive than the Tripps.

I bought a batch of Check-Mates a year ago and began using them as I was completing work on a Springfield 5" this past summer. During a range session I was experiencing multiple inertia feeds which had me completely flumoxed. I could not for the life of me figure out what was causing these malfunctions until i disassembled the magazines and found that the followers were sticking within the tubes.

Normally, the follower should move freely up and down the length of the tube due to its own weight and gravity (obviously the spring has to be removed).

I called Check-Mate and was asked to return the magazines to them. Check-Mate is not a tiny company, 1911 magazines are not their only product, and I'm just a single consumer. Nevertheless, the president of the company got personally involved and within days I had brand new, fully functional replacements in hand.

The president and I swapped several e-mails in which he explained that the problem was due to an error in the heat treatment of the tubes during the manufacturing process.

Bottom line: major kudos to Check-Mate and their commitment to customer service.

Good on Check Mate, I'd heard of them, but not much experience or hot/cold reviews about them. I'm pretty sure they make mags for Colt or have in the past anyway. Pretty sure that I have one or two about somewhere.

What CMC mags were you using, Shooting Star or Power Mag? I have a couple 10 round Shooting Stars that I've found OK for range use, but am hesitant to use them for carry. Have had several 1911 fanatics recommend Chip's Power mags with Tripp followers. Have not tried them myself, Wilson's 47 D mags have been working well for me.

Have had several 1911 fanatics recommend Chip's Power mags with Tripp followers.The Tripp followers will reduce capacity by one. To be honest I was never real happy with the CMC followers tilting forward with the last round and dinging up the frame. Not a functional issue - I just didn't like it. I've replaced all the innards of all my CMC mags with Tripp's Super 7 upgrade (follower and spring) which knocks the mag capacity down to seven but they feed like greased lightning plus the follower doesn't ding the frame nor does it slip past the slide stop lug which happened only a very few times with the CMCs.

Being something of a 1911 nut thanks to Uncle Sam making me carry one for lots of years, I know that stuffing 8 rounds into a 7 round length tube wears out magazine springs much faster than putting 8 rounds into an 8 round length tube. Both the Check-Mate and Tripp mags use extended length tubes so that the springs won't stack into a solid mass with no space between the coils when they're loaded to capacity. This is good for spring life. I like the Tripp springs and may use them in the Check-Mate mags when those springs eventually need replacement.

Good to know, was looking into that and couldn't determine if a round capacity was lost or not.
Thanks.

Any experience with Brownell's 8 rounders?

Any experience with Brownell's 8 rounders?I have no first hand experience with the Brownell's mags. I only know what I've read. The word on the street is to avoid them. However, I might get one with my next order just to see for myself if they work.

Interesting, I have original Wilson/Rogers 8 rd mags with the plastic followers that didn't damage the feed ramp.
