I am looking for a mag well and basepads to work with preban Para magazines. I have a 1640 with a Dawson mag well. I live in state, that shall remain nameless, where new large cap mags are not legal, so I am limited to the preban versions. The preban mags, which are a couple of mm shorter than the new versions, do not seat correctly. They do not feed well and/or drop free.
What set up did people use before the ban expired? Is there a better mag well than the Dawson to use with the preban mags, or can I just relieve the Dawson back far enough to make the basepads seat correctly. On the Dawson sights it says that there basepads do not work with the short mags.
