Munch Posted January 3, 2019 Share Posted January 3, 2019 (edited) Searched many posts but did not want to hijack so thought I would start new. Just bought used (looks like new) 1997 small frame Witness 9mm (see picture). I did most of Memphis video polish job and although smooth still would like to work on that trigger pull. Will use only as range gun so want a lighter trigger without breaking the bank so would like to start with springs. I know! sucks that front sight is fixed so may look at that down the road. Hammer spring- Needs to be the longer traditional type. Everyone talks about the Henning and Patriot but as far as I can tell these are all the newer transverse spring. Joe at Patriot told me they are looking at coming out with the longer spring soon. The only other one I see would be the Wolf longer hammer spring. Any help here on spring and weight would be appreciated. I load my own 124g and use only Win S/P primers. Would be nice to get by without messing with firing pin but open for suggestions. EDIT!!! Now I am not sure - see pic below Reduced Power Sear spring - Which one for this gun? Patriot? Ideas Reduced Trigger Return Spring- Patriot? Reduced Trigger Plunger Spring- Henning? Sorry to be so long winded but would appreciate your suggestions. Here's the pic . Edited January 3, 2019 by Munch Link to comment Share on other sites More sharing options...
MemphisMechanic Posted January 3, 2019 Share Posted January 3, 2019 Glad the videos helped. If it has a long spring... can you use one out of a CZ? Link to comment Share on other sites More sharing options...
Munch Posted January 3, 2019 Author Share Posted January 3, 2019 Yea The videos are great Memphis. Where would you get the cz spring and what weight do you think I could try first with Win S/P primers. Pencil test about shoots to the ceiling so seems pretty strong. Also do you think the other springs I mentioned and brands would work and be worth it? Link to comment Share on other sites More sharing options...
Munch Posted January 3, 2019 Author Share Posted January 3, 2019 (edited) Woah!! Hold the train. Now I am not sure. I pulled out again and not as long as I thought. See new pic above Edited January 3, 2019 by Munch Link to comment Share on other sites More sharing options...

See new pic above You have the SHORT spring. Buy 13, 14 or 15.5 from patriot. Polish the strut. Some old ones are larger diameter, you can reduce diameter of the strut. Ive use a "gasp" file to make it smaller then polished mirror bright. Polish the plunger assembly inside and out. That will probably be all that is needed. If you want the Henning spring is OK, but will make reset feel mushy if too low. PD for the other parts. Reduce power sear spring AND the firing pin return spring.

Munch Posted January 4, 2019 Author Share Posted January 4, 2019 Thanks johnbu. Yea since it was older I was letting the info on Wolf"s site sway me into thinking I had the traditional long spring. I will look into the P/D spring. Just curious if you have one of the P/D hammer springs and could measure the ID. Then I would know what If I will be grinding the strut? - Will also look at the P/D optimized firing pin spring -Is the P/D reduced power trigger spring worth using? Thanks Lynn Link to comment Share on other sites More sharing options...
johnbu Posted January 4, 2019 Share Posted January 4, 2019 Don't over think. But the spring. If it slips on .... done. if not, fix it. The PD trigger spring will drop 6-8 oz. Your call Link to comment Share on other sites More sharing options...
HesedTech Posted January 4, 2019 Share Posted January 4, 2019 I bought the same pistol a few months ago. Shoots great. Typical Tanfoglio polishing I installed: PD reduced trigger return spring. Henning reduced plunger spring. PD reduced sear spring. PD firing pin spring. The normal Tanfoglio hammer spring for the S2 is too long. So I used a PD 15.5 lb spring and cut coils off until it didn’t bind. Basically same length as stock one from the gun. DA 6.5 SA 2.3. Smooth and crisp with stock sear and hammer. Fires off primers better than my S2. Great budget pistol and uses CZ 75 mags. Link to comment Share on other sites More sharing options...

Those that don't like to trim springs, the PD 14 is essentially equivalent to a PD 15.5 with coils cut. Wolff also makes a 15 # spring that is short.

Munch Posted January 5, 2019 Author Share Posted January 5, 2019 I ended ordering all the above PD springs and the PD 14 to start with. Can’t wait to try! Link to comment Share on other sites More sharing options...
Munch Posted January 12, 2019 Author Share Posted January 12, 2019 (edited) Ok so I received my springs from P/D but the 14lb main spring ended up to long stacks up and won't let hammer go all the way back. (See pic) Can I trim the 14lb? Get the 15.5 and trim it? Get a Wolf? Appreciate all your help! Edited January 12, 2019 by Munch Link to comment Share on other sites More sharing options...

For some reason the depth of hammer spring pockets flucate on some guns for some unknown reason. When we created these we took the average depth across 10 guns to determine OAL. Usaully getting rid of the dead coils on each end will get you full travel. Link to comment Share on other sites More sharing options...
Munch Posted January 12, 2019 Author Share Posted January 12, 2019 Do I want to match length spring for spring or try one coil at a time? Link to comment Share on other sites More sharing options...

Did the pencil test and sends it about 3 ft. up in single action. Guessing about 3.5 lb. pull now S/A 7.5 D/A so a lot better. Will be a few days till I get to the range so will report back later next week. Really appreciate the help. Link to comment Share on other sites More sharing options...
MemphisMechanic Posted January 12, 2019 Share Posted January 12, 2019 Thanks for the update. That’s about the pull weight I’d expect without going crazy and dropping in things like a 1 piece sear, high dollar hammer, and extended firing pin block with all the attendant fitting. I’d leave it alone at this point. Shoot & enjoy. Link to comment Share on other sites More sharing options...
Munch Posted January 12, 2019 Author Share Posted January 12, 2019 Sorta what I thought. Can't wait to get to the range? Memphis -Always pulled your video up when I had to do disassemble! Appreciate it. Link to comment Share on other sites More sharing options...
