Glock 26 A compact 9mm Glock with 10+1 capacity. Higher capacity magazines will fit and work, it just defeats the compact purpose. What’s interesting here is that it’s resting on the massive muzzle brake for the Bushmaster BA50. The muzzle brake is heavier than the Glock 26 loaded. The BA50 is a bolt-action .50 cal rifle with some parts compatibility to the AR series of rifles, mainly just the stock and pistol grip.
