I've looked at the 10 point Kahr Lube Diagram (http://www.kahrtalk.com/showthread.php?14750-Kahr-Lube-Diagram) but noticed there is no mention of any oil being placed on the trigger assembly. Is that needed?

There is nothing in the Kahr manual that shows or describes specific lube points. Pull up the manual (https://www.kahr.com/PDF/kahrmanual.pdf) and search (Ctrl F) for "lubrication". You'll discover that "lubrication" appears only three (3) times within the entire manual; once in the Table of Contents; once in the discussion of magazine maintenance; and once in the heading "Cleaning and Lubrication". If you search for them, you will also discover that the words "lube", "oil" and "grease" do not appear anywhere in the document.
The only lubrication instructions contained in the Kahr manual are: "Once cleaned, all parts should be lightly lubricated with a commercial gun lubricant. Follow solvent and lubricant manufacturer's instructions."
Kahr provides no specific or explicit instructions about lubrication. Therefore we are left to our own experience and judgement about where, what kind, and how much lubrication to use. That means the responses you'll receive to your question are a matter of opinion, and not fact supported by Kahr.
My opinion about the need to lubricate a trigger is that there is so little movement within the trigger mechanism, lubricant is not needed to prevent wear. That said, a very light application of lubricant can make the action feel more smooth, and I do lube the pivot/contact points on my triggers--but very sparingly.
That is not a practice that should be recommended to everyone, however. If one is meticulous about cleaning their guns, and does so frequently, there is no harm in lubing the trigger. However, lubricant does eventually evaporate leaving behind solids which can harden. Guns have been brought to me with "frozen" safety mechanisms, because the owners applied a liberal coating of gun oil at the end of hunting season, and a year later (or more), the safety was "frozen".
Because I've seen so many instances of the operation of a firearm becoming disabled because of improper maintenance, I am reluctant to advise owners to lube triggers (and strikers). If, however, you strip, clean, and lube your firearms regularly, and you keep them in a clean environment where dust, dirt, and grit won't be attracted to the lubricant, there is no harm in light lubrication.
Sorry for the long-winded response, but a mere "yes" or "no" answer, without a rationale for the opinion, is not very helpful to others.

I find it odd that Kahr does not instruct where and where not to lubricate their pistols. Isn't that what a manual is for?
Luckily someone provided the ever so helpful 10 Point Kahr Lube Diagram found on this forum and elsewhere among the interwebs.

I put one small drop of oil on the trigger return spring when I first got my CM9 and haven't lubed it since. That eliminated a slightly gritty trigger feel when dry firing the gun.
Excellent and insightful response, RRP - thank you.
You're welcome. Glad I could help.

WD40 is one of the worst offenders for turning from lube to adhesive.

I use a tiny needle point oiler to touch a bit of lube at any spot that rubs, pivots, spins or slides on a trigger mechanism. Modern firearms need very little lube.

I've decided to give the mil-comm products a try. I plan to use their TW25B grease on the rails. Has anyone used both the MC2500 oil and the MC3000 Semi-Fluid? If so, which one do you prefer as a protectant?
