i've got a 1927 F.M.A.P marked one .it was issued to my dad while on the navy target team in the fiftys along with an h&r leatherneck and a p17 accurized with a tomphson sight. being a cheif when he drummed out they surplusd his guns out to him. he sold the p17 but kept the sight and the 1911 and the H&R. if u like shooting that try a gold cup. mine runs like a sewing machine.how our navy ended up with a colt systima i have know idea.probably screwing with my dad.
