Light Primer Strikes with PRP Safety Lever PLEASE HELP

[nateroach]

So I went to the range today for the first time after installing my Powder River Safety Lever. I installed the Safety lever in both my 9mm service and my tactical .45. The 9mm functioned flawlessly, but my .45 suffered from several light primer strikes (approx 40% of rounds fired were light strikes). I didn't put more than 40-50 rounds through it because I didn't want to cause any damage due to the light primer strikes. My question is how do I fix this problem? I am thinking that I need to file/grind off some material on the safety lever in the area that it engages the sear (shown as sear engagement face in pic (stole the pic from mcb hope you don't mind))



Is this the correct way to stop the light primer strikes? if so, how much do I need to remove from the sear engagement face? Please help

Thanks

I am no expert, Daniel will know better than me, but when I fit mine Daniel did mention that the "sear engagement face should sit completely flush against the notch on the sear. The point of this, as Daniel explained, was to do with the grip safety. I do not understand how this could affect the strength of the hammer. If you do want to be check and be sure that the lever is fitted in this place, follow this:

Take the sear and safety lever, but the rod in the middle of them, put the safety lever on the sear and see if there is any gap at all between the sear's notch and the safety lever. If there is, take a round needle file and file the sear engagement face until it sits flush with the sear's notch.

I have a quote from Daniel that I received in PMs on how to fit his lever.

If your trigger is not reseting you need to fit A. A is the tab that the trigger bar hooks on.
If your grip safety is not engaging the sear, fit B. you can check B by setting the sear down on the work bench and assembling my lever on top of it with the pin installed. move the lever forward until it engages the tab on the sear. check to make sure that it is NOT contacting at point B. the tab of the sear should be contacting my lever directly below point B and the surfaces should be parallel.

Two ways, AND, I'd tell you to ask Daniel.

You can either file a small amount of the sear contact face directly below Point B in the photo above. The light strike will be because of drag by the striker safety. Filing the area below Point B will let the lever rotate further up and push the striker safety out of the way. I would try not to take off more than .005" before trying it again.

Or, adding a little more overtravel may also work. Probably the easier choice, but results in longer resets.

If you lay the parts down on the workbench as Daniel suggested in the above quote, you can prove this methodology to yourself.

I agree the light strikes are due to the striker safety not fully being depressed before the sear releases the striker ( i see a small amount of rubbing on the striker safety at the back). I think that the striker is catching the striker safety just enough to slow down the striker and cause light primer strikes. I believe by removing a small amount of metal from the sear engagement face (directly below point B) will allow the safety lever to depress the striker safety further before engaging the sear and releasing the striker. I don't think that it has anything to do with the point labeled A, as the trigger is reseting. I tried increasing the over travel at the range and it did not remedy the light primer strikes.

If anyone else has any ideas please let me know.

thanks

Well, seems you've diagnosed the problem. The sear contact face on the striker safety lever is gonna be the place to tune. Be sure to look at how these things work together and understand why that's the place to tune, so that you're not anxious having to trust a bunch of online XD nuts!!! LOL

Can you post a pic of the lever siting on top of the sear with the sear pin holding the parts together? Here is an example of what I need to see


The black arrow points to the suspected problem area. In your case I think that the sear is cocked down and this is reducing the time that the safety lever needs to do it's job. In any case this is the first time that I have heard of this happing with my kit. I will send you a new one asap. All that I ask is that you send my the one that you have so that I can inspect it and find out what went wrong. I'll pay the postage.
Regards,
Daniel

Daniel,
Right on. GunnBugg and I installed your Match Trigger Kit on my Dark Earth XD last week in prep for my match and it was worth every penny. I ordered on Monday and had it Thursday. Thanks again for the help, your prompt, courteous and professional support speaks volumes of you and your company. Oh, and Semper Fi, Marine!

Daniel thank you for the great customer service, it is clearly top notch. I am currently at work, so I will post pics after lunch.

thanks again for the help

Ok here are the pictures of the safety lever and sear as you requested Daniel.







It looks like the safety lever is sitting correctly on the sear tab, but this is after I removed some material from the sear engagement face. I don't have any pictures of the safety lever and sear before I filed the sear engagement face. I have not had a chance to test fire it since I filed down the sear engagement face so I can't be sure it has stopped the light primer strikes. Does it look correct?

Additionally I looked at the striker safety (pic below) I see some wear on the back side of the safety tab, is this ok? I know there was a big discussion about this in the threads about the group buy sear problems and want to make sure that it is ok.




Thanks for all the help guys, i doubt that I would have a clue what is going on in my gun if it weren't for this forum.
