I recently purchased a few "RA" marked magazines for my Hi power clone from sportsmans guide. I was disappointed to find that they don't move at all when the mag release is depressed. My factory BHP magazine at least drops a little when released. This sucker just sticks. Now, I am in the market for some 13-17rd magazines by whoever makes a quality one. I have only ruled out the factory 13 rounders because they are so damn expensive. Right now Megcar is on the top of my list but I don't know what else is really out there and proven. I am hoping to spend no more than $30 per mag, so please factor that in. Who makes a good one ? Thanks - Texmex
