How funny... my father bought his .38 while stationed in Tucson Az still flying for the then-new USAF in the post-war years. Then he was reassigned to Carswell, Ft. Worth in 1949 and exited the service there to work for Convair. The old .38 did home protection duty there and when we moved to California in '61.
These guns are decent home defense guns especially for the budget-minded. Since many of these conversions have little collector's interest many have been modified or reblued. One gun I saw was used as a project gun and the owner had it blued in the late 60's... by COLT! Interesting to see an S&W M&P with a high lustre polish and Colt bluing!
