Not possible with my gun, I already had the frame machined for the Chen MSH (installed in picture) so I’d have to go full weld on.Don't flinch, but the Chen magwell is the way to go. Minimal, and I do mean minute, filing to blend the leading edge with my Tisas Carry. The chute itself was a spot-on channel.
I’m not a huge fan of extended mag wells on carry/hard use guns for a couple reasons. First they tend to print a bit more when trying to conceal. Second, in a potential force on force scenario (grappling) they can get bent. If that happens the mag will be trapped in the gun. Probably not a massively realistic scenario but neither is a mid gunfight reload in a civilian context.
