My 2014 RAMI has what I would call a hard plastic base on the 10 round magazine. I have embraced the two finger grip for that gun but there are those that have modified a Pearce grip extension, model PGXD. The mod entails gradually sanding the top lip of the extension with relatively fine sand paper until a magazine fitted with the extension will consistently engage the magazine catch and function 100%. I tried the mod on one of the Pearce extensions and got it to fit and function, but at the end of the day just preferred the two finger grip with the pinky finger curled under the base of the magazine. I have extra large hands so that may contribute to my preference.
