Colt Mark IV Series 80 Government .380 Auto at the range. Why ammo testing is important!
This YouTube video showcases a range day with a Colt Mark IV Series 80 Government .380 Auto pistol. The creator intended a casual range session but encountered significant ammunition feeding issues, particularly with Fiocchi round nose and Winchester white box flat nose ammunition. The video emphasizes the critical importance of thorough ammunition testing in new firearms, especially for self-defense purposes, to ensure reliable function. The Colt .380 performed exceptionally well with Golden Sabre hollowpoint and Hornady Critical Defense ammunition, highlighting the dramatic difference in performance based on bullet type and brand. The creator plans to conduct further testing with other .380 ACP loads.
