Well, I decided to go right to the source, and got this back from TruGlo:
Below are our sight offerings for KAHR Arms pistols.
Models K, MK, P, PM, T and TP - (excludes P380)
TG13KA1PC TFX Pro green front (orange Focus Lock)/green rear
TG13KA1A TFX green front (white Focus Lock)/green rear
TG231K1W Tritium Pro (White Focus Lock)/green rear
TG131AT1 TFO green front/green rear
TG131AT1Y TFO green front/yellow rear
Please note, these sights will ONLY fit the above model pistols, with the new style dovetail cut, produced after 2004.
KAHR Arms pistols K, MK, P, PM , T and TP produced after 2004 will have a pronounced and easily identifiable dimple that has been machined into the rear bottom of the slide…see highlight in photo to properly identify this production mark
So it looks like we are out of luck with the P380 as far was TruGlo is concerned.
So this raises another bit of confusion. They say that the new dovetail came in 2004, and this can be confirmed via the dimple on the underside of the slide.
However, my MK9 (serial number GC00xx) has the pronounced dimple, yet--according to the charts I've seen--was manufactured circa 1998. So either Kahr started rolling out the updates earlier, or my MK9 got a new slide from the previous owner???
l'm inclined to question the 2004 date. My MK9 is a "GA" serial series and has the new style rear dovetail (and the dimple).
