I have a 38/200 wich I believe is same as 1905 4th change. According to S&W 4th edition commercial version has grips with medallions which mine does and they # to the gun. Book also says military version has lanyard ring which mine also has, and it looks factory with grips off. It is 38 S&W with 5” barrel. There are no markings or import proofs on gun. There is a P on opposite side of lanyard ring from serial #. So do I simply have a commercial/civilian model that left the factory with a lanyard ring for whatever reason? I’m sure someone WAY more knowledgeable than me knows the answer. Thanks.
