I had forgotten about this thread. Your 03 looks nice. I really suck looking at photos but it does look like a fatter barrel then "normal".
@MarshallDodge have you looked up her SN# and checked her dates? Should be able to find out if she was special. I think springfield has records on all of them, the real springfield that is even if she was made by RI....again the real RI. Yours is a real looker, the stock looks a little like an "air service" model, but those had the Rec cut to take a detachable box mag, 15 or 30 rounds I don't remember what. They are very hard to come by, and at one time, till some dude told the world about them on the internet got passed over for being a bubba job and went cheap. That guy even talks about that as well.
Here is basically my home shootin setup. The old mower and wagon are great for hauling things to the back of the property where I shoot. Don't judge too hard, I am a poor old country boy.
My 03 is to be one of those that if you listen to the "internet" it will blow my face off, kill everyone in a 100 square mile radius, and knock the earth out of orbit and send it spinning into the sun. Oddly enough I have never had an issue with anything "full power" loads on down. Currently she gets fed "youth loads" in 3006, but that is more a "me" thing and I can't do recoil like I once could. She is a perfect example of one of the "low number" springfields that are to have issues, a October 1918 dated barrel, so this thing likely has not been touched after 1918
If you can see from the barrel pic it is a Rock Island barrel, this is really nothing to worry about. They did mix and match barrels straight out of the factory. Remember there was a real war going on and getting gunz in the hands of soldiers was the only thing that mattered. Something to keep in mind when looking at really any of these old gals, parts not matching was common. The M1 carbine is a perfect example, be very suspect of an "all matching" carbine, someone likely made it that way.
