Big Dog Howie Posted January 26, 2014 Share Posted January 26, 2014 (edited) We have installed Hennings flat trigger along with EGW's Hammer And sear with all of Hennings oversized pins on my Witness Elite Limited in 9mm,the problem I am having is when the hammer falls it goes to half cocked.This happens probably 8 out of 10 times when dry firing,also had this problem at a match and had to switch to my Stock II.I am about ready to just put back all the stock parts back in,I just hate spending $300 on upgrade parts to just take them out and put them in with all my spare parts. It looks like the leg on the sear is longer than the factory sear and I observed marks on the top of the safety as if the sear is striking the safety when the hammer falls causing the hammer to bounce off of it. Anybody have this problem and remedy it Edited January 26, 2014 by Big Dog Howie Link to comment Share on other sites More sharing options...
cpa5oh Posted January 26, 2014 Share Posted January 26, 2014 I have the EGW sear and hammer, and my hammer bounces off the firing pin and goes to half cock when I dry fire it also (about 2 of 10 times.) That hasn't caused a problem in live fire... Link to comment Share on other sites More sharing options...
Big Dog Howie Posted January 26, 2014 Author Share Posted January 26, 2014 I have had problems with live fire could not even shoot the match,and it now goes to half cocked everytime during dry fire.My gunsmith is going to work on it tomorrow,it should not be doing that ever. My open CZ never does that and I have CGW adi sear and CZC hammer and run a 8.5 hammer spring with a flat trigger and CGW trigger return spring.

Justsomeguy Posted January 26, 2014 Share Posted January 26, 2014 Few firing parts are "drop in". A sear and hammer along with a safety usually need some work. Hopefully your gunsmith is someone who recognizes this and the gun will be as per specification when you receive it back. Link to comment Share on other sites More sharing options...
CleverUsername Posted January 26, 2014 Share Posted January 26, 2014 Didn't Chalee post once that egw hammers half cock ledge has to be worked over to prevent issues when installed. I cant find the exact thread, hopefully he will chime in. Link to comment Share on other sites More sharing options...
Big Dog Howie Posted January 26, 2014 Author Share Posted January 26, 2014 Thanks guys for all the info I'm sure we will get it fixed Wish these tanfo's were as easy as CZ's to get running Link to comment Share on other sites More sharing options...

Hopefully your gunsmith is someone who recognizes this and the gun will be as per specification when you receive it back.He is aware of that but these Tanfo's seem to take a bit more fitting than my CZ's to get perfect.i posted not because of my Smith's lack of knowledge but looking to cut to the chase that is anyone who has encountered this issue might shed some light on it Link to comment Share on other sites More sharing options...
Nealio Posted January 26, 2014 Share Posted January 26, 2014 Thanks guys for all the info I'm sure we will get it fixed Wish these tanfo's were as easy as CZ's to get running They are...?

Mlussoro Posted January 27, 2014 Share Posted January 27, 2014 thats what i was going to say could just be over travel screw. these guns are really simple as nealio showed me one day in the garage! Link to comment Share on other sites More sharing options...

Who fit the star? I always like to thank anyone who inputs regardless of what they input Yes we checked over travel. I have spoke with Henning he told me that this a problem and that the bottom of the hammer makes contact with the trigger bar. He told me you need to take some material off the hammer in this area so we did it helped but its not perfect. He says he is trying to get EGW to correct the problem. Well see how it runs this sat at our match but will have my Sock II as back up.if it still won't run we will put all the stock parts back in after a thorough polishing I can't have a non functional match gun. It could be I got a bad hammer geometry could be off a little to cause problems Edited January 27, 2014 by Big Dog Howie Link to comment Share on other sites More sharing options...
Big Dog Howie Posted January 27, 2014 Author Share Posted January 27, 2014 Update, we discovered that if you use a snap cap when dry firing it never goes to half cocked,but without the snap cap it almost always goes to half cocked Link to comment Share on other sites More sharing options...
Nealio Posted January 28, 2014 Share Posted January 28, 2014 Oh its bouncing up. sorry I thought you meant it was catching on the 1/2 cock notch. How did this prevent you from shooting a match? Anyway, you just need to take a dremel and grind a relief in the base of the hammer. Mine look ugly as hell. Link to comment Share on other sites More sharing options...
Big Dog Howie Posted January 29, 2014 Author Share Posted January 29, 2014 (edited) Nealio can you post a pic of what you did.And yes it bounces but goes to half cocked.Doing the Bic pen test (to see if the firing pin strikes)it does not go to half cocked but hammer falls all the way but with nothing in the chamber for the for firing pin to strike it goes half cocked Edited January 29, 2014 by Big Dog Howie Link to comment Share on other sites More sharing options...
Nealio Posted January 29, 2014 Share Posted January 29, 2014 I'll try to take a hammer out tonight unless someone else has a pic handy.. Link to comment Share on other sites More sharing options...

Big Dog Howie Posted January 31, 2014 Author Share Posted January 31, 2014 (edited) Wow that's a bunch,so it should mimic the stock hammer.Did that eliminate the problem? Edited January 31, 2014 by Big Dog Howie Link to comment Share on other sites More sharing options...
Nealio Posted January 31, 2014 Share Posted January 31, 2014 Yes, cutting a relief in your hammer stops the bounce to half-cock. Here is one out of one of my guns: Link to comment Share on other sites More sharing options...
Big Dog Howie Posted February 2, 2014 Author Share Posted February 2, 2014 Thank you Nealio Link to comment Share on other sites More sharing options...
Glk21C Posted February 2, 2014 Share Posted February 2, 2014 Just like Nealio shows here, I had to do the same to my EGW hammer. It's easy, just go slow. If you have a stock hammer to use as a guide as well it helps. Link to comment Share on other sites More sharing options...
Big Dog Howie Posted February 3, 2014 Author Share Posted February 3, 2014 Still need to do the cut but shot the gun yesterday at our local match and it ran100% not a hiccup.bugs me that the hammer bounces back so I will do the grinding this week. Want to thank everyone for their Input this forum has a wealth of knowledge and I appreciate that. Surprised tho that you did not chime in kneeling atlas Link to comment Share on other sites More sharing options...
praetorian97 Posted February 3, 2014 Share Posted February 3, 2014 My Tang is getting a custom fitting for the EGW hammer and sear as we speak. I feel like I'm 10 again waiting to open my Captain Powers Xmas presents. Link to comment Share on other sites More sharing options...
Birddog6424 Posted February 6, 2014 Share Posted February 6, 2014 I'm ordering Hammer an Sear tomorrow. Dan is ordering it for me (for the local guys who know who Dan is). He get's it a little cheaper than retail. I'm also going to get the Henning trigger, but just not sure if I need it. I like the current pull weight of my trigger at about 3 lbs, I just can't stand the pre- and over-travel. Link to comment Share on other sites More sharing options...
