experience with Witness sear?

8strings8rounds · January 29 2017 06:47:45 PM MST

Ok, I spent the last two days carefully shaping the hooks on my hammer and shortening the reset leg on the sear on a Tanfoglio Witness Hunter. There are no videos on this part of the gun, only some shotty, vague opinions in forums thinly spread across the web..
As I understand, the sear is case-hardened and reshaping it will cause premature failure.. So I can't work on it the way I want and it's driving me nuts ${$default_sad_smiley}$
What can I do about trigger creep? This gun came with the most god-awful trigger of anything I've ever owned and it seems I can only fix it so far.
Does anyone have any more experience working on these, or can point me towards a forum or video that gets into the detail I need?

Thanks in advance

Given the price point of the gun, I suspect it is a high quality MIM part, and filing/stoning it would probably create issues.

best advice I have is lube it good and get 1K round through it. Mine has smoothed out very nicely. Feels like a good two stage trigger at this point.

Thanks! I'll try that sear.
I lightly polished the stock sear which smoothed out the action, but There was only so much I could do to to it without probably messing it up.
I'll probably buy a couple in case..

I will make a video. The stock hammer is a Combat hammer. Mine was swapped with a Limited hammer. Could that make a big difference?

Please do.
If there's a difference, it's gotta be in the hook angles. It's a very odd lockup compared to say a1911..

I'm still running the original sear and trigger parts.

Have you done anything to them? Was the hammer a noticeable difference?

I guess I'm not too sensitive to the thing you have going on. Can you video it or explain it to me?

8strings8rounds · January 31 2017 06:17:02 PM MST

I should have taken a video before I did all the work, that would have shown it more clearly. I tried recording it, but what I'm feeling doesn't pick up on camera ${$default_shocked_smiley}$
You know how you can actually see the sear where it engages the hammer? Watch it as you pull the trigger slowly. From the time the sear begins to move to when the hammer drops- feels like a mile to me.
In my 1911s, revolvers and 3rd gen S&W's, there's virtually no perceived trigger movement in single-action. You place your finger on the trigger and as soon as you apply pressure, it just snaps.
I bought this Hunter over the stock iii for two reasons- 6" bbl and SAO thinking that the single action would be nice, it's almost there now with all the work I've done.. But not quite.

Here is another issue with the pistol that I'm having-

I believe this is extractor related. There's some brass marks on the slide, but the brass looks good and was all within 20' of me.. It was just scattered all over.

Nature of the 10mm beast! Have you cut the ejector down yet?

8strings8rounds · February 01 2017 10:20:49 AM MST

Not yet. I'm going to do that after I get a spring and enough ammo for another good afternoon of tuning ${$default_grin_smiley}$

They use the same one for all calibers and cutting it helps some.

I have a new recoil spring on the way, and an extractor (just in case)
I noticed a consistent, though small, ding on every casing and managed to match it to the edge of the ejection port. It appears the shells are kicking too hard/too soon, so I will be making some small changes to that ejector.
