Welcome. I am curious what caliber you are referring to when you say 38? Having bought my first US Army 1st Model, I have done quite a bit of research and found that these guns were chambered in 38 MIL, which actually means 38 Long Colt. A 38 Special should not fit in an original Army or Navy, so I was happy to find that mine would not chamber a 38 Special. My understanding, however, was that lots of these guns were rechambered after they left military service. Finding one in original 38 LC is a treat, plus this and the Navy Model were the only S&W ever chambered in this caliber that I can find.
I was fortunate to find a nice one, except for a shortened barrel. Of course the price was very good, even for a shortened barrel gun. I was extremely lucky to locate an original Army 38 MIL barrel to put on the gun that had a serial number that was within 100 of my gun. It goes great with my Krag rifle, and both saw service in the Phillipines.
I love the 32 and 38 Model 1899 revolvers and am never disappointed with the function of these guns. Simply flawless, except for one thing. The barrels had no forcing cone and some will ocassionally shave my soft lead wad-cutters. No big deal, but I make sure there is no one on either side of the cylinder when shooting.
You did not state your serial number, but assume it falls into the 1000 Army guns from 13,001 to 14,000?
