Trouble with the new trigger bar.

[mcb]

As some of you have seen my thread on installing the new trigger bar into my XD-40

But now I am having a very annoying and intermittent problem with my XD. It will run perfectly for a stage or two and then on the next stage it will fail to fire several times and the next stage it will be back to normal.

The problem is real intermittent and is proving hard to track down. It is either failing to reset the sear and thus the striker is following the slide home and will not fire or more likely the internal striker block is sometimes not getting lifter sufficiently high enough to disengage it and the striker does not make it to the cartridge since the striker block stops the stiker.

When the problem first happed I simply filed little more material off the over travel stop to make sure the safety block was getting lifted enough but this did not fix the problem It maybe I need to go higher but then my trigger will basically be back to a factor amount of over travel.

Is there a slick way to make the safety lever that disengages the striker block rotate up higher without filing any more off the over travel stop and without modifing the safety lever. Its one of the parts on the do not sell list (just called).

At present I am back to my factory trigger bar until I can resolver this problem. It really hosed me last weekend at a special classifier match. I probably should have gotten a B classification in Limited (already B in Limited-10 and Revolver) but ended up in C class because of the malfunctions. Any suggestions would be more than welcome. The parts issue with SA is really bitting my in the butt today. I am pretty sure I could make it work if I had a spare safety lever to modify. Might have to CNC my own safety lever it this turns out to be the problem.

Try increasing the sear spring pressure. Our service had to light of a sear spring at one point and the side was beating the reset.

Sound like you probably don't have enough pre-travel in the trigger. Especially since you stated that it isn't reseting.

Take the springs out of the firing control in the slide and put the striker back in. Put the stirker with no springs in the slide and put the slide back on the frame. If pull the trigger, you can look down the back of the slide and watch what the striker safety lever push up the striker safety block. you will see what is going on. If you don't have enough pretravel, the striker won't clear the block.

Feel free to give me a call.

That's the problem I am not total sure if it is reset problem or an internal safety block problem. At present my pre-travel stop just lets the trigger come far enough forward to re-engange the trigger safety. How do you know if you have let it come far enough forward for reliable resetting?

If I compare my XD-40 Tactical to my Service with all factor parts the safety lever does not come up nearly as much in the Tactical with the springer sear and new trigger bar. It does pass the pen test very nicely. It will send a bic pen pretty much the same height as my Service.

The real perplexing part is I can never get it to malfunction with snap caps or doing the bic pen test, only when shooting live ammunition. Even then it is very intermittent.

ichy_trigger I will check the sear spring. If the lighter spring that comes with Springer drop in sear but that is fairly new.

Thanks guys

The method I described above will tell you if the LB is an issue.

The reset is harder for someone who doesn't done a lot of them. Push it down with the slide off and make sure it has no resistance popping back up, if it does have resistance you will need to work the part until it doesn't.

I know this is an older post but I am curious what the out come was? I am thinking of doing a Springer kit on mine but a little nervous if there are issues doing it myself.

I believe I have solved most of my problems. Detail in the following thread: XD Trigger work, redux (sear, trigger bar and safety lever)
