CT45 and CT40 Trigger

[Purple Mountain Outdoors]

So I just picked up a CT45 and CT40 and I really like them. I noticed right off the bat, the CT45 has a seemingly longer than normal Kahr trigger that is way lighter and smoother than normal. The reset is very light, almost imperceptible.

The CT40 on the other hand is a little heavier than normal, and also not quite as smooth. Also the travel seems significantly shorter than other kahrs and has a loud, tactile, almost glocky reset (very nice).

Any ideas as to why this is?

Do the TP40 and TP45 exhibit the same differences?

I'm not really sure.

If I could I'd take the lightness and smoothness of the 45, with the shorter, better reset of the 40.

The triggers on the CT45/CT40 should be the same as the P45 and P40 (or TP45 and TP40). They're the same parts.

There are some variations that should be expected. The reset ... I can see one feeling more distint than another. Same thing for smoothness. They all smooth out eventually though.

In my experience, the lobe on the cocking cam that unlocks the firing pin tends to be an area of stacked tolerances. If the lobe is too long, the hole in the slide too short, the locking piece too long, or the spring not quite right, the frame to slide fit on the tight side.... you'lll get a no-fire situation. I'm only saying this because since it shows how variations do exist.

I've got one PM45 with a seemingly longish trigger pull, and another that the other PM45 I've got has a shorter pull. But, what's happening is... the trigger pull is being arrested by the full upward movement of the firing pin locking piece. It fires ok, but... if you pull and hold the trigger fully rearward, then you've locked the pieces and the slide is hard to rack. One of these days I'll correct the fit. I imagine it will take only a very slight fitment of the firing pin locking piece.

Can't say that there'd be any variation, except for the variation you'd see between two samples of the same model.

I have to say, I do really like this CT40, but I seem to be more accurate with the 45. This is probably due to the significantly lighter trigger in the 45. Though the 40 seems to be loosening up as I dry fire it.

Remember this - surface smoothnes, spring rate, and the hand fit interface of the striker to the release lobe.... are all gonna be a factor in your trigger pull.

My CT40 really smoothed out after a few range sessions, but my P9 trigger remains the smoothest of all my Kahrs. But I do like the reset of CT40 trigger, as you refer as being "glockish". BTW PM me I have a deal for you on spare mags for your CT40.

take 5 PMJ9 and they will all be somewhast different. Just sayin
