No. .38 S&W is larger diameter than .38 Long Colt. Just like .38 S&W won't insert into a revolver chambered for .38 Special, it won't into the M1899. .38 Special is just a stretched .38 LC case to allow more black powder to be loaded.You can probably also chamber and fire the very similar 38S&W and or the British 38-200. All of them preceded the longer and slightly skinnier and more powerful, modern 38 special
You can find 38S&W for sale, online
No. They were primarily .38 S&W Special. Some guns made for the Army, Navy and Cutter Service were chambered for .38 Long Colt. No hand ejector was chambered for .38 S&W until the Regulation Police I frame was introduced in 1917.None of the 1899 were 38 S&W?
Serial number is 6647. No sign of any other markings in the barrel regarding chambering. Chambers are in good condition. It must be a 38 caliber(32 is clearly to small when tried). Barrel is 5 inchesIt is not a military gun with serial number either 6647 or 8847?? Looks like a 5 barrel and if so it is uncommon to find. It should have the caliber stamped on the left side of the barrel, but the metal is so beat up, I cannot make anything out. Only other caliber available was 32 Winchester, but the serial number is too high. Has to be a 38 Special barrel. Do you have commercial 38 Special ammo? Check the headstamp. If so, is the chamber rusty?
Wile I learned something new.No. They were primarily .38 S&W Special. Some guns made for the Army, Navy and Cutter Service were chambered for .38 Long Colt. No hand ejector was chambered for .38 S&W until the Regulation Police I frame was introduced in 1917.
I was excited by the idea of having a 38 long colt.. dreams crushed haha I did in fact test it with 357. 38 spl seats perfect. Thank you for the help.One further thought is the ammo you are trying to chamber. Does it say 38 spl or 38 special? I want to be sure it is not 357, for example.
