I wanted us to go with a recoil operated 7.62 for long fields of fire, and fully automatic 12 guage systems for jungles and urban warfare.
I had an HK91 that would fire under pretty much any condition. It was infuriating that my service weapon was so inferior {albeit lighter} to the G3.
Along with my 1911 .45 I carried an Ithaca 12gauge with shortened barrel in Vietnam. This violated Marine Corps doctrine of officers to carry weapons only for personal protection. As far as I was concerned it WAS for my personal protection! I never had to use it, thankfully.
Bingo! Will go anywhere with my M1 and Saiga 12.
