I would need to know the Browning model number besides the serial number to get you any info on your semi-auto browning pistol.
Contact Browning or compare against known examples.
By the serial number, then try: http://www.browning.com/customerservice/dategun/index.asp
The barrel will be marked "Made in Belgium"
Please ask again and tell us which model you have / Automatic / Over Under ???
You'll have to tell what it is (rifle, shotgun, pistol) or go to Browning.com and look up the sn under the customer service button.
Call Browning with the serial number.
