Picked up one recently, and I hate it. Half the time I can't even tell if the dang thing is seated in the mag well. No "click". Next, I have never had a magazine with so may FTF issues. It got so bad today that I now have to take the thing apart because there are ten rounds left in the magazine, and top one has jammed so hard in the feed lips that I can't even pry it out with a screwdriver! So, I guess it's either back to Butler Creek, or splurge and get a Tactical Innovations mag.
