Tirppa Posted July 12, 2019 Share Posted July 12, 2019 (edited) is this the normal shape? Like those two humps are normal? I thought it is supposed to be a continuous arc. I only used metal polish and soft polishing tip on dremel so I'm pretty sure I didn't manage to do those but can't be sure. Now after changing parts (titan hammer, extreme disco, bolo, pd springs) there is a huge drag at the beginning of the trigger pull as the trigger bar sits in the very front of the plunger and has to clear both of those humps. Then again also the bottom of the trigger bar where the plunger sits is super rough (like really deep grooves). Am I just better off buying new trigger bar and plunger?

PatriotDefense Posted July 12, 2019 Share Posted July 12, 2019 It’s hit or miss on quality or uniformity from Tanfo...... with that said the drag is more than likely the rough lathe work on the trigger bar plunger rod and the ID of the trigger bar plunger head.

Tirppa Posted July 12, 2019 Author Share Posted July 12, 2019 (edited) Yeah the trigger bar is a mess.. I'm wondering if the xtreme parts would be any better. It's a second hand gun from 2008 and I'm the third owner. The last two did't give it too much TLC. I did smooth out the plunger rod but I guess there's still some roughness inside the head of the plunger. Edited July 12, 2019 by Tirppa Link to comment Share on other sites More sharing options...
PatriotDefense Posted July 12, 2019 Share Posted July 12, 2019 Head of the plunger is a bear to get done correctly Link to comment Share on other sites More sharing options...
Yondering Posted July 12, 2019 Share Posted July 12, 2019 Your trigger bar looks pretty much like mine in a new Stock II a couple months ago, and standard model Witness pistols 10-15 years ago. You'll need to polish that rough grooved area in the center of the bar where the plunger head rides. The plunger head should be one continuous arc, not those two bumps.

Polymer Posted July 13, 2019 Share Posted July 13, 2019 If possible where you are located, i would just buy a new trigger bar spring plunger assembly. Don't waste your time on that one. Here in the states they are very cheap, $10 https://patriotdefense.com/tanfoglio-witness-trigger-bar-spring-3-7-3-8-3-9-3-10/ Link to comment Share on other sites More sharing options...
Tirppa Posted July 13, 2019 Author Share Posted July 13, 2019 Thanks for the replies. Ordered new guide and new bar just for the heck of it. Asked Eric if it wouldn't be too much to check that the trigger bar guide wasn't a total piece of crap. Link to comment Share on other sites More sharing options...
