One of the least produced 3 Model 19s. One of only 55 made for Lew Horton in 1995 and the only Model 19s done by Mag-Na-Port for Smith & Wesson. These have the two ports where all other Carry Comp (K Comp) have the one power port forward of the front sight. Does not have the usual Lew Horton and Performance Center product code starting with 17xxxx but used the same product code as the 2.5 matte 19-5s made for the Diplomatic Security Service (100701) so have lettered as having a 2.5 barrel. (I do not have a letter for this revolver.)
A quick breakdown of the other K Comps
Around 1500 Stocking Dealer Specials made in 1994-95 with SDA prefixes and laser etched markings.
90 made for Lew Horton in 1997 with KCP prefixes and roll stamped markings.
Only 55 of these made for Lew Horton in 1995.
and then of course there is the current production 19-9s that are still being made.
