400driver Posted April 12, 2017 Share Posted April 12, 2017 (edited) Have a Shadow Viper using a Cajungunworks competition hammer that has been an incredibly accurate gun. After much use the sear is getting a small amount of wear as it rubs against the harder hammer. The gun is a target pistol and is used only in single action. I installed a CGW billeted sear to match the hammer and the problems started. On trigger release the hammer would fall a short amount and would not drop completely. The sear clears the hooks but does not make it all the way down to the firing pin. Could it be that the hammer is interacting with the wings of the disconector ? In single action, do I even need the disconector installed. Here is a link to a you tube video of what happens. I would be really grateful for any suggestions about fixing this problem. I have reinstalled the original sear after stoning out the slight rounding of the lower sear edge. I would like to have the CGW sear as it will reduce the wear over time. The trigger is incredibly crisp after stoning the curve and remains so for a few thousand rounds.

SlvrDragon50 Posted April 12, 2017 Share Posted April 12, 2017 I don't know what a Viper Sear is, but if you have a post-travel adjustment screw, it is too tight. Link to comment Share on other sites More sharing options...
400driver Posted April 12, 2017 Author Share Posted April 12, 2017 Viper is a CZ Shadow with a 6 inch slide made by a German gun maker. Sear is the same as a shadow. Not sure it is that as you can continue the trigger pull into the original double action. Will give it a try though.

SlvrDragon50 Posted April 12, 2017 Share Posted April 12, 2017 (edited) Neat! The screw that you see sticking past the trigger towards the rear is the post-travel adjustment screw. You need to loosen it so the trigger can travel further to allow more sear clearance. You probably had it set tighter with the worn sear which resulted in more sear wear. You want to make sure it has enough clearance so the hammer isn't grinding away the sear material slowly.

400driver Posted April 12, 2017 Author Share Posted April 12, 2017 Ok. Just replaced the CGW sear for the original sear for a big competition at the end of the month. As the sear clears the hooks that would suggest that there is enough over travel. I will wait till then to give it a try. It's adjusted perfectly now and has virtually no over travel after the hammer drop. It is an incredible pistol, glad you like it.

400driver Posted April 12, 2017 Author Share Posted April 12, 2017 Will have a look at it. Do you know if the disconector is needed for single action only? Sent from my ONEPLUS A3000 using Tapatalk Link to comment Share on other sites More sharing options...

Sent from my ONEPLUS A3000 using Tapatalk take the disconnector out. no need for it in SAO. but it is pretty cool if you cut the wings off and use it as a pretravel limiter. that is awesome.

400driver Posted April 12, 2017 Author Share Posted April 12, 2017 I already have a small screw tapped into the side frame which controls the pre travel. I can just turn the screw and it changes instantly the position of the trigger. Sent from my ONEPLUS A3000 using Tapatalk Link to comment Share on other sites More sharing options...

400driver Posted April 12, 2017 Author Share Posted April 12, 2017 So just cut the wings off completely? Sent from my ONEPLUS A3000 using Tapatalk Link to comment Share on other sites More sharing options...
eerw Posted April 12, 2017 Share Posted April 12, 2017 it needs to be a short reset disconnector too. but yep. Its a cool mod on a SAO gun. Link to comment Share on other sites More sharing options...
