get a grip, really
Our patent pending uni-directional serrations allows the operator to grip the basepad without snagging, but when its pulled the serrations latch on offering unparalleled manipulation in the harshest conditions possible.
Got one to try out and it’s pretty cool. Seem well made. A clean flush fit. A bit tight loading that last round into the mag. It is new though. Currently loaded with 135gr Critical Duty in a Kimber DS Warrior.
Great mags at a great price. Fit my Watchtower Apache Commander perfect.
Absolutely stellar. Very pleased with these magazines, as well as the service and prompt shipping from Checkmate. I had been on the hunt for 2011 mags that do not rattle when loaded and was beginning to think that there was such thing in existence. Was delighted to find that these mags, with their new spring geometry and tension, have zero rattle and feed perfectly. They also feel very sturdy and the stainless steel bodies are nicely polished. Very well done. Hope to see rebuild kits for these so we can keep them running for a lifetime.
Awesome product!
Great quality and finish
Mags for my Kimber 2k11 Royal arrives quickly and loaded and inserted into the pistol flawlessly. Well-constructed of stainless steel I feel these will last and give me consistent performance. I highly recommend these for all Kimber 2k11 gun owners!
Great!
