Awesome Piece

This magwell is a perfect fit and finish as well as taking the aesthetics to another level! All though that is secondary to performance this thing is top notch! Don’t waste your money on cheaper garbage this is worth every penny!

Well designed!!!

I saw these mag bases on a YouTube channel, and I had to get them. The PSA Micro Dagger mag bases do flex, or warp, under pressure, when loaded to full capacity. I was concerned that this warping, could potentially cause a catastrophic failure, at the worst possible moment. These CMC Mag Bases install easy, and when the mag is fully loaded, they are solid, and do not bow, or warp.
These CMC Mag bases are well designed!!!

PSA Dagger Micro +0 Magazine Baseplate – Black Anodized

Micro Dagger Base-Plate

I now run these on the Micro-Dagger mags in my Glock 43X. They run flawless but the original base-plate leaves much to be desired. After "seasoning" the mags for a couple months fully loaded the Original base-plates were bulging outward from the tension. This is a known issue with these mags. The CMC base-plates solved this problem. They look and function like OEM Glock Products. Bought two and now placed a second order. A satisfied customer here.

Beautiful fit

It goes on very nice, it doesn't push your grip up but it doesn’t matter since people have different hand size, it provide good index point. The bottom of the magwell fit the frame well. Regular psa magazine without base pad will work but have a little interference. But once i put on the CMC base pad and other brand base pad, it work beautiful.

Dagger Micro Magazine Base Plates

These are by far the best. The fit and finish are spot on. If you’re thinking about getting some don’t hesitate. Also works great with Grit Grips magwell. Thanks for a well made U.S.A. Product.
