It's A European Thing
GLOCK just announced updated versions of Glock 43X and Glock 48 Slimline models for the E.U. market. These are the all black versions that debuted in the U.S. a few weeks ago, but these Euro GLOCKs have one very important feature: accessory rails.
Rails are an important feature and quite frankly I thought it was a bit odd GLOCK did not to offer rails on the new U.S. G43X and G48. Many users like to have the option of adding a tactical light or laser. Perhaps U.S. models might get the E.U. rail treatment in the future.
