This Model 19-7 K-Comp is from the second production run (1997 for Lew Horton), and is numbered in the "KCPxxxx" prefix. The first run of K-Comps was made for the Stocking Dealer Program (1994) and were serial numbered in the "SDAxxxx" serial number range.
The K-Comp model included the frosted blue finish, radiused trigger (w/trigger stop) and non-tear drop shape hammer (the earlier production run had that style), along with the front night sight and "power" style muzzle port. The original rubber grips are long gone in favor of Spegel Boot grips.
