Glock 38 pistols in 45 GAP from Omaha Outdoors are the same size as a Glock 19 or Glock 23 but instead of those puny 9mm or 40 S&W cartridges, the G38 carries 8 rounds of 45 GAP, a cartridge ballistically almost identical to 45 ACP. For those who value size above everything, the Glock 38 punches way above its weight class.
For American pistol shooters, the 1911 type handgun holds a special place in history and is still relevant even today. With seven rounds of 45 ACP in the magazine and one in the chamber, the 1911 won a lot of man-to-man fights for good guys over the years. The Glock 38 takes the capacity of a 1911 and adds another round to the mag, meaning it's legal at max capacity even in states with magazine restrictions. While other pistols firing smaller bullets are forced to leave empty space in the magazine, the Glock 38 fills the whole thing with extremely potent 45 GAP cartridges. That's a strong argument for a lot of gun owners who may be on the fence about buying a gun in a new caliber.
