My son gave me a LCSmith as a retirement gift. The serial number is 214799 and it is a 1912 5E. I believe the barrels are Nitro Steel and I was wondering if I need to shoot low pressure loads. The gun has a two barrel set, each with the same serial numbers; one 28" and the other 30". Also, any information on what this gun might be worth; it is in great condition and has not been restored. I do not intend to sell it, but was just curious as to its market value range.
