I've got a chance to get some cheap, are they any good?
I'm the "Jon" that Andy was referring to. For the past several years, our local IDPA has been field-testing magazines for Check-Mate, which over time has led to them sponsoring 6 of us. We've also done several large group buys with Check-Mate; users have been very pleased with them, and any hiccups encountered (which have been rare) have been very expeditiously handled by Check-Mate under their lifetime warranty.I particularly like the new 8-round extended "hybrid" magazines. You've seen them as factory magazines for some Dan Wesson guns, and I believe the Ruger 8-round magazine is this as well. Tom Vieweg's patented follower is steel, with a dimple and a decent skirt to prevent the follower from jumping out as easily. There's a fellow on here, Jon I think his name is, who has been doing some long-term tests with them.
