Magpul continues to build out the impressive array of Enhanced Handgun Grip modules for the joint Ruger-Magpul RXM pistol. 

Launched late last year, the RXM uses a Ruger-made stainless steel serialized Fire Control Insert system inside a polymer grip made by Magpul. In its standard format, the RXM is an enhanced take on the Gen 3 Glock 19, down to the 15-shot flush-fit magazine, most internals, slide, recoil assembly, and barrel. We've even swapped out G19 slides to run on the RXM and vice versa. 
 

Now the polymer princes of the gun industry have doubled down on the promise of the RXM's modularity by announcing full-size and subcompact variants of the EHG, with each planned in the four-color format as in the standard model. 
 

Both sizes will run just $39 and include the assorted small parts (magazine release, release spring, slide-lock spring, and takedown-pin spring) so that the owner of a standard RXM just needs to drop in their serialized Fire Control Insert and attach the slide assembly to be ready to go. 

Therefore, one could just grab a standard 15-shot RXM (MSRP $499) and add one each of the full-sized and subcompact EHGs from Magpul ($39 x 2), plus a couple of mags for each extra grip size ($15 x 2 x 2), and for less than $650 (even at full retail price), have essentially three differently sized pistols.  

Magpul plans to have the new EHG sizes out shortly, and naturally, we'll let you know how they work.
