They've been in business for a long time selling parts, pieces, and lots of shotgun supplies. They have the very 1st corner booth at Friendship every year. John, his wife, and his son Mike all take turns running it. Mike also sits on the NMLRA's Board of directors with me. Bunch of nice folks there! As for the locks though, I can't say as I've ever even looked at one. The company is a reputable one though so take a chance and let us all know how it goes.
