alvo89 Posted August 3, 2017 Share Posted August 3, 2017 Title pretty much says it. I just got a Tanfo Stock II and was installing the Wolff 13lb hammer spring from my Witness upgrade kit. However after a long day I had a lapse of focus and mixed up the stock hammer spring and new Wolff hammer spring so I'm not sure which one I installed/replaced. I do know that one I put in the gun with the other upgrades is longer than the other. I tried squeezing each of the springs and the longer one felt lighter i think. Gun functions perfectly. The DA pull "i think" feels lighter however it's not substantially lighter so I cant say for sure especially after mixing up the springs. Anyway can anybody help me or know their hammer springs? Any help is appreciated. I will be installing a new sear, hammer, and BOLO soon so I will have to disassemble the gun again at some point. Link to comment Share on other sites More sharing options...

alvo89 Posted August 3, 2017 Author Share Posted August 3, 2017 I can get some. What do you need pics of specifically? I do know the shorter spring that isn't in the gun is a little under 1.25" long. Link to comment Share on other sites More sharing options...
MemphisMechanic Posted August 3, 2017 Share Posted August 3, 2017 Post a photo side by side. The 13lb spring should also be made from thinner wire. Link to comment Share on other sites More sharing options...
alvo89 Posted August 3, 2017 Author Share Posted August 3, 2017 Ah, one of them is in the gun right now. I'm reloading at the moment but I can strip it down pretty quick (your vids are plenty helpful Memphis ). Link to comment Share on other sites More sharing options...

The ends of the left spring are cut be flat. Right spring ends are just cut and twisted to an end. Edited August 3, 2017 by alvo89 Link to comment Share on other sites More sharing options...
alvo89 Posted August 3, 2017 Author Share Posted August 3, 2017 I think I got it figured out. Longer spring is the 13lb Wolff hammer spring, I could feel the DA pull more smoothly by way of being lighter, still gritty with the factory parts and could use more polishing. With the original shorter spring, you could really feel the wall towards the back of the DA pull. Mistakes made and lessons learned. Link to comment Share on other sites More sharing options...
MemphisMechanic Posted August 3, 2017 Share Posted August 3, 2017 (edited) The longer one is the 13. Correct. You're also right in that a good polishing job is responsible for at least 50% of a light, smooth DA trigger pull.

johnbu Posted August 3, 2017 Share Posted August 3, 2017 Masking tape. Write the poundage and IMMEDIATELY wrap the spring with it. Link to comment Share on other sites More sharing options...
mjmagee67 Posted August 3, 2017 Share Posted August 3, 2017 You could always use a trigger pull gauge to tell them apart. Not too hard to install try it, then install the other. Link to comment Share on other sites More sharing options...

The first time you leave a spring like that for two years in the garage's heat then try to remove it, you stop doing that. Scraping that hardened tape crud off isn't fun. They go in small ziplock baggies inside a tackle box type clear plastic tray, now. Edited August 3, 2017 by MemphisMechanic Link to comment Share on other sites More sharing options...
zombywoof Posted August 3, 2017 Share Posted August 3, 2017 I keep the original bags. wright the date you install the spring on the empty bag. Link to comment Share on other sites More sharing options...

And i do have some 2 year old taped springs that untaped cleanly. And i know acetone dissolves the adhesive. ! Link to comment Share on other sites More sharing options...
