Tim with the Military Arms Channel delves into his personal and extensive collection of TEC-9 pistols including some interesting open bolt variants.
Designed by George Kellgren — the Swedish gun wonk who later went on found first Grendel and then Kel-Tec — the little 9mm pistol with its forward magazine well was extremely popular throughout the 1980s and 90s until people had a chance to fire them.
Tim starts with the o/g version, the reliable open bolt Interdynamic KG-9, in the above video before switching to the KG-99 and the more commonly encountered but frequently jammed TEC-9. And yes, he shows off that classic TEC-9 reliability or lack thereof.
Also, be sure to be on the lookout for some open bolt MAC 10 and MAC .380 cameos.
