    I had around 200 rounds through my P3at before I went to the range this morning to try and see if the fail to extract issue has been resolved.  I fired about 60 shots and luckily I had no extraction problems.  But I had about 10 rounds that were very very light strikes and did not fire.  In the first 200 rounds I had zero light strikes.  I noticed on the misfires the hammer sounded funny.  I removed the slide so I could get a better look at the hammer.  I placed my thumb forward of the cocked hammer(to prevent a harsh overtravel of the hammer) and lightly pulled the trigger, after it pulled back and released it went right back to the center cocked position and did not follow through.  This is why it wasn't firing.  If I pull the trigger fast it will really whack my thumb...If I pull it slow like you would while target shooting it just lightly snaps forward to the center position.  I am fully releasing the trigger between shots and am doing everything correctly.  It just started this morning.  I searched and didn't find any answers to my problem.  Does anyone know what is causing this?  

    Here is a video of the problem...

    Is the trigger behaving normally. Check the trigger pin. If it has backed out, it may not be engagning the hammer properly. Usually when this happens, you will notice the trigger not working properly, but not always.

    Another possibility is that the hammer is slipping off the trigger bar too soon. The easiest cure for that would be a new trigger bar which is easily replaced. Look at the hammer also to see if it is worn, nicked, etc where it engages the bar.

    This disassembly link is for the P11 and 1st gen P3s but most of the info applies.

    This link involves trigger mods on the P11 but may help shed some light on how the hammer and trigger bar intereact.

    Great video. I can't really recall seeing one do exactly that - particulary the part where releasing the trigger moves the hammer forward. It's unusual. Again it could be the trigger pin or the hammer not properly engaging the trigger bar.

    Now you have another option. Email the video to KT. Title it VIDEO OF HAMMER PROBLEM, or something easy to recognize. Then followup with a phone call to service and ask for a P3AT tech. They aren't often good at responding to email. Get one of the service folks to view the video. They can probably tell you in an instant what part/s need changing, and service could send them to you.

    i would think the trigger bar (white) is not pulling the hammer block (blue) far enough foward

    I agree with JFB!

    Do you have the new "anti-short stroke" hammer block on yours?

    I could not duplicate your problem with my old style hammer block P-3AT.

    I think your hammer pin (part #276) http://www.kel-tec-cnc.com/images/downloads/p3atv2manual.pdf is catching on the edge of your hammer block (part #272).

    Did you install a "White Trigger Stop" by any chance? http://www.ktog.org/tecwerks1.htm#White Trigger Stop

    Could your trigger pin (part #253) have worked itself down?

    With the slide assembly removed you should be able to observe the operation of the hammer and hammer block.
