Metalform is curently making the magazines for Detonics USA, in accordance with new feed lip specifications by the headgunsmith. It's my understanding that these new specs match the way he used to handform the lips on the "ACP" mags that went through his repair department at the Seattle/Bellevue factory. The new mags also use the "loaded magazine indicator" that the original ACP mags featured. (The Metalform mags that were made for "New Detonics" in Phoenix, AZ didn't have the indicators, or the right feed lips). You can buy the new mags off of the Detonics website at www.DetonicsUSA.com. I've got a couple of 'em now and they work great.
