“…there's plenty of material at the front and the rear to increase the space for the cartridges. However, given that they're solid walls both front and rear and the magazine has a curve to it, it'll be a little tricky to get in there and evenly remove material to make more space. If I were doing it I'd probably use a die grinder with an oval shaped carbide on a 6" shaft. Additionally, the follower will end up being too short and I have no idea if that will cause reliability problems due to it tipping, so what I'd try to do would be, as much as is possible, make a meplat-shaped groove in the front wall instead of removing the front wall and trying to leave a flat surface on either side of that groove for the follower to index on and then only removing material in the middle for the noses of the bullet to fit into. It's a double-stack mag, so I'm not really sure this would be possible but that would be the goal.
We ARE having these production-quality 3D printed by a major operation. That means it's pretty darn straightforward for us to have our engineer open up that inside length and scale the follower to match. To make like 10 of these mags the per unit cost would go up, because we'd be looking at maybe an hour of our engineer's time (potentially less as I don't foresee any real difficulty) plus a low-volume run on the commercial laser 3D printing machine. Might end up being like $95 a pop instead of $50, but it's something we can do if you're serious about needing some
. In theory we'd do this and offer it as a separate product if there were demand.”
Essentially sounds like there’s some space to
decrease wall thickness and thus increase internal length. Basically just thinning out the walls and increasing the length of the follower to properly fit.
If guys are serious about having some made, let me know and I’ll put together a list/rough number for them to work up a cost.
