I have several P14 magazines that do work in my P13, and in my Taurus 24/7 OSS.
I saw P14 magazines on Greg Cote LLC.

This is the only gun I've found the worked with Pro Mag's.
(I have several useless Pro Mag's for Sig P220)
Armscor P2 1911 double stack also fit, I don't know how well they work.
The 14 round magazines just stick out the bottom of the grip.
