I had the opportunity to examine a FN/Browning model 1905 “Vest Pocket” pistol that was made around 1910 or so. It is in good condition overall, but the bore and chamber show signs of pitting that appears to have been caused by the use of corrosive primed ammunition. I presume that corrosive primed .25 ACP was in existence during the early 1900’s? I thought that non-corrosive ammunition was commercially available in these early years, much sooner than when the military began using it. This pistol belonged to a member of “Merrill’s Marauders”, but it is unclear if he carried or used it in the jungles of Burma during WWII. The conditon of the bore could be attributed to the environment there, but externally there are no signs of damage from the elements, making me wonder if the pistol was with him then.
What can you guys tell me about .25 ACP ammunition from the early 1900’s?
