There is a sporterized Krag section you can check out here at the KCA forum. There are many sporterized Krags floating around out there that bring shooting pleasure to many people. Most of us have at least one sporterized Krag even if we are original Krag addicts. So, you're in good company.

I don't have my references here to tell you if there is any documented military history for your specific Krag. Others will chime in and give more info but pictures tell lots more than just the serial number.

What does the rear sight look like? What numbers are on the slide? The rear sight tells a lot about the Krag. There are rifle rear sights and specific rear sights made for carbines because they have different barrel lengths that change the ballistics of the bullet. Carbine rear sights are marked with one or more "c"s to designate the carbine design.

There are pictures on this forum also that can help you identify what you have.

Keep the info coming and pictures when you can.
