You have likely bent the slide stop spring during reassembly.
It's easy to bend, especially when new, and easy to fix.
You can order some springs from the Kahr web site.
And you'll need one of those torx thingies (I think it's #8 or #9?).

You have to be very careful, especially when tight and new,
inserting the slide stop into the frame.
Insert at about 4 o'clock part way in.
Move slide to the correct spot.
Then rotate the slide stop to 3 o'clock.
And carefully push the rest of the way in.

I did the same thing.
BTW my MK40 Elite got much better at 200+.
But wasn't 100% reliable until 400+.
At that point she will feed anything and runs like glass.

MK40's are fine weapons once you get past the break in.
And master the re-assembly procedure.
Good Luck

BTW KahrTalk.com forum is a great place to resolve Kahr related issues.

Thanks for your suggestion. I visually inspected the Slide stop spring and it did not look bent. The part you pointed me to does not look anything like my slide stop spring. Also, according to the manual the part number should be 029M4E not 028M4E. Do you know why the part numbers in the link you gave me do not match the part numbers in the manual?
