.50gi magazines are undoubtedly the best ones I have seen. Here is Ned Christiansen's take on Alex's .50gi magazines (from his post on TOF in 2004): "The magazine is a real piece of work. It's very significant that the body is made from heat treated stainless (you can plainly see that it's been through an inert-gas bright heat treating process) that is .006 thicker that the steel used in a .45 magazine. .006 doesn't sound like much but that's about a 25% increase. The follower is machined from Delrin and has a heat treated steel insert where it contacts the slide stop. The removable floor plate is machined from, no wait, it is machined for cryin'-out-loud from, steel, and Parkerized to match the gun. There are two small holes per side in the body to show full and when there are at least two rounds left. One of the reasons the Wilson magazines work so well is that they hold the rounds measurably higher than others (remember a couple years back when the design was improved? Guess who?). The GI mag also holds the rounds high and angled upward. The mag will not be a weak spot, that seems sure." For those who did not see them here is a quick look: The one on the left is .45 with .50gi one on the right: What are Guncrafter's magazines on their .45 models? Are they compatible with standard ones? I would guess so..Would appreciate your inputs.
