Two things I don’t like about Gen 5 baseplates are I find the design more prone to pinching during a reload, and the big problem, is the magazines don’t work in a regular 19X. Despite good intentions, I can see a Gen 5 magazine ending up in a mag pouch when you have a 19X.
How much material needs to be removed from the X magwell to make a Gen 5 base plate work, and is that something you can do by hand with a file?
