You are correct. 1903/04S & W .38 Military & Police Second model - 1st change (I belive) #55xxx
1973Could someone tell me the year of my model 28-2?
serial # N174***
1977. The "J" prefix eliminates it being a model 19.Friend of mine would like to know what year his revolver was made (either Model 19 or Model 37) #J558361.
No. My two Freedom Arms revolvers will not accept a .002" gage and have no issues when hot. However, if that was your problem, you would see the contact/drag marks on the face of the cylinder.Just purchased a feeler gauge and ran the .004 and .003 through the gap (barrel/cylinder) and it's snug. Would this be causing the binding issue after it gets warm?
S&W 686 AEK48xx
Post war Military and Police. "K" frame. Made 1960. The model number (most likely 10) should be stamped on the frame underneath the cylinder yoke, visable when cylinder is open..38 cal

Well... according to the book, 31-1 started 1961 as a "J" frame at serial number 712954. Your serial number dates it to late 50's as a "I" frame but that's before the -1 change. So.... I dunno.M31-1 (it says " A 77 31-1 "), s/n 673xxx, round butt, 3" barrel, cal 32S&W Long. I guess this is an "I" frame.
