We just started offering the extensions for our magazines and because they are so new, most likely not many people have tried them yet. At this time they aren't in full distribution yet because the retail packaging had to be updated and currently are each just in a plastic bag.
We do think it is a good product and our engineers have performed testing with them. If you have any questions, we would be glad to answer them.
I've used your products for a few decades and haven't had anything to complain about. Thanks!
Numerous people have used your plastic +2 extensions on M&P mags to good effect. Any chance these'll work with them as well? As there's this rumor going around that you're already making the M&P mags anyway.
At this time we have only tested the floorplates on our magazines and not on any others. We are limited in what we can advertise them as fitting because we are mainly an OEM company and don't want to cause any ripples with pistol companies whom we manufacture magazines for. I wish I could give a better answer than that about fitment of these floorplates.
