The 10 Round B&T APC9 Standard Magazine is the best built of the magazines for the APC9 from a design aspect. With the hard elastomer bumper on the bottom of this magazine, you can see this is top quality choice in the design of the magazine and can withstand impact. You can still even add the Elastomer bumpers over it for additional protection to your magazines. I cannot stress how nice this is. I originally picked up two for range practice, but I couldn't help getting more.

Good service from BT-parts.com. Fast shipping and item as described. Only note, which was a pleasant difference is that the base of the magazine is black and color and not gray as it would appear in the photo.
