It surely sounds as if they have their customer service dept running well. Replacing the defective mags, and taking time to thank you, thats the sign of a quality Co. I will bet on most anything, as long as my life doesn't depend on it. I would try their mags, Cav, given your comments, and their letter, and on the other post, they said, they were getting the bugs out. If a Co. has a bad batch. or even one bad employee,(in cus. serv.) the Co. can get a reputation as being bad. Kalinka optics, comes to mind, they have great customer service, and seem to sell quality items for a good price, I posted as much, a few weeks ago, and whoa-did the flame throwers erupt. but I am happy with my purchase, as well are you, and that is what matters. +1 for CP, for replacing defective mags, and writing a letter in their defense,an +1 for cav. for taking time to give a honest report. I will certainly give you a thought, the next time I get new mags, which is never soon enough. Thanks, Alan
