JaneDoe released R Series grips in G19 size for RXM use that accept Generation 3 G19 slides, the RXM FCI, and reversible magazine catches for G19 generations 4 through 6. The lineup spans R19, R19L, R19X, and R19XL frames, with R19L and R19XL excluding G17 slides and R19X adding grip length for 17 round magazines. Files remain unfinished, this is not a serialized firearm component, and state plus local laws must be checked for compliance.
