Anyone know of a basepad that can be added to the factory mags to make them hold 20? Gun comes from the factory with 17 round mags. Or any other mags that will work?

These are Caspian frames right? Wouldn't Caspian mags work?

The caspian pads should get you to 20...

Henning pads work great on my caspian I can get 21 in them

The Caspian Quick Change Base Pad should get you to at least 18 with the stock spring and follower, if you add a Gram's engineering spring and follower (for the tanfo/caspian mags) you should get to 20 pretty easy, and maybe 21.

The Henning H141 base pad can also be used as TRP said, although I expereinced a little interference with the new Henning H141 pads and the EGW magwell on my Caspians, so I just stick with the caspian quick change pads.

What mags came with the gun? Seems like as Paragunner said they are probably Caspian mags and already have the quick change base pad to work with the magwell extension. If that is the case call Gram's Engineering and order some tanfo/caspian spring and followers (they are slightly different than the ones used for STI/SVI mags).

Search for Caspian mag posts, especially those by jjanglin and RIIID as they shared a lot of knowledge about tuning Caspian mags.
