I am the son of an Armed Guard Gunners Mate. I can talk about two side arms. Because when we lost Dad I inherited them.
One was his Colt 45 1911A1. According to the serial# made in 1943 the year Dad signed up. I have the documents transferring it from the Gov't to Dad the year of his retirement 20 years later. Almost 70 years old and I put 50 rounds through it at the range last week. By far the best firearm ever made. Even better that it was Dad's. My son is currently active duty Navy and the standard issue side arm is the Berretta 9mm. However one day he will get his Grandpa's 1911A1.
The other found its way home from Murmansk. Dad always called it a Russian pistol. When it passed on to me I did some research. It is actually French made. When the Nazi's rolled through France they captured the arms factory and forced continue production under occupied France. It is Nazi stamped. If Dad picked it up in Murmansk I could only imagine a Russian soldier took it off a German soldier. Also about 70 years old. I put 50 rounds through it last week too.
