We've mentioned the very cool upgrades for Glock handguns available from Vickers Tactical (sold through TangoDown). It didn't take long after the new G42 came out for the same types of practical upgraded parts to become available.
Should you feel the need to add some practical upgrades to your new pocket Glock, there is now a Tactical Slide Stop, Tactical Magazine Catch and Magazine Floor Plate uprade available. The Tactical Slide Stop offers a re-shaped thumb pad for improved operation without additional heft, making release of the slide simpler even while wearing gloves. The Tactical Magazine Catch extends the magazine release and offers a contoured edge for sure purchase. The Magazine Floor Plate offers just a little more real estate for resting your fingers while shooting, not enough to hamper concealment but enough to make shooting just a little easier.
