Glock’s .45 GAP round was designed to provide .45 ACP performance in a shorter cartridge that would fit into a standard size Glock grip frames. However, the compact G38 and sub-compact G39 .45 GAP pistols were released with the over-built .45 ACP slides installed, which made the pistols thicker and heavier than the 9mm and .40 S&W pistols with the same grip size. This design choice may well have contributed to these pistols and cartridge not becoming as popular a Glock hoped. But the engineers at Lone Wolf Distributors recognized that it was possible to build a slimmed-down .45 GAP upper assembly with the same profile as standard compact and subcompact models.
This stainless steel slide assembly, along with a .45 GAP magazine, will allow compact (G19, G23) or sub-compact (G26, G27) pistols to be converted to the .45 GAP round and still have the pistol fit standard holsters. The assembly can also be used to slenderize the G38 or G39 models. This caliber conversion is so new that Lone Wolf doesn’t even have a name for it yet, let alone a price. But they say it will be available for purchase soon, so stay tuned.
