Decent, however has a design flaw
The mag worked fine for a few outings. Then, just as the review stated in pthor's review my mag started to break down. Towards the rear of the magazine, you will see 3 tabs on either side of the magazine. There are slots on the outside of the magazine walls. The tabs are supposed to fit inside of those slots. My top left and middle tabs sheared off. (Unsure how as there was no damage to the magazine). The resulting pressure of adding in rounds puts too much on the outside walls. This causes the walls of the magazine to bow outward, the elevator is no longer contained and you get the wonderful result of having loose rounds fall all over your floor and the elevator and spring zooming out. This happened the morning of opening day of deer. To resolve the issue temporarily (in case this happens to you), you can crimp down the side walls with a pair of pliers or vice grips. However, the pressure will be too great if you load more than 1 round, and the magazine will not want to come out of the gun easily. At least this way, if you're planning on hunting with the gun, you can slide one into the chamber and then load the magazine. 2 shots are better than one! I have emailed Brownells asking for a replacement, they have great customer service and obviously they are just selling the product. If I receive a replacement and it works well out of the factory I will change the review, however there is very clearly a design flaw here. My guess, they are trying to turn out a relatively affordable magazine and to keep costs down on an old firearm line they stamp the sheet metal, and just use tabs for retention once they assemble, instead of welding them. Understandable, but it is a weaker design.
