ny32182 Posted July 5, 2016 Share Posted July 5, 2016 (edited) So I have recently been trying to tune up a stock 2 from scratch by myself for the first time. I'm not a gunsmith. I've polished what I believe are key points, and resprung to specs similar to what I have in my other guns. I think it came out well with the exception of the single action trigger break, which is noticeably heavier than it is on my other guns. It had a stock two piece sear, so I ended up changing that out for a one piece, and I have a Titan hammer in it (first gun I have with one of those). The DA is fine, but the SA just breaks heavy and I would like it to break lighter. I have polished the edge of the sear, but not tried to remove any metal or change the shape. I have not touched the hammer hooks on the Titan hammer. What do you think I should do? Edited July 5, 2016 by ny32182 Link to comment Share on other sites More sharing options...
johnbu Posted July 5, 2016 Share Posted July 5, 2016 Change to a cz sear spring, cgw reduced power trigger spring, polish the pin and holes in the sear. Than dry fire the piss out of it in SA. Link to comment Share on other sites More sharing options...
ny32182 Posted July 5, 2016 Author Share Posted July 5, 2016 CGW reduced power TRS is already in it. Sear spring is stock Sear holes and pin are stock Link to comment Share on other sites More sharing options...
kneelingatlas Posted July 5, 2016 Share Posted July 5, 2016 The single action break is all in the hammer hooks, polish the snot out of them and you'll be good to go. Link to comment Share on other sites More sharing options...
fellas Posted July 5, 2016 Share Posted July 5, 2016 just shoot the gun as it is , it will become perfect after couple of 1000 rounds , and avoid ruing sear and hammer hooks with too much polishing this what eric grqauffell told me . Link to comment Share on other sites More sharing options...
johnbu Posted July 5, 2016 Share Posted July 5, 2016 The single action break is all in the hammer hooks, polish the snot out of them and you'll be good to go. Are the Xtreme sear and Titan hammers through hardened or just surface? What about the factory heart hammer? I'm reluctant to even touch sear interfaces that might be only surface hard.

JusticeOfToren Posted July 5, 2016 Share Posted July 5, 2016 Among my 3 tanfos, the only one with < 2lbs SA pull is the one with 2-wing disco. The 2-wing disco came from the Limited Pro and I put it on one of the Stock 2s. The other two have the 1-wing disco, and their SA is around 2 lbs 10 oz. All of them have titan hammer, factory one-piece sear, CZ sear spring and factory TRS (I found that using the CGW reduced power TRS actually adds 0.5 lbs pull). All 3 had the about the same polishing done. I contribute the lower SA pull to the 2-wing disco. If anyone knows where to buy the 2-wing disco, I'd buy 2 more and put them on my other guns.

ny32182 Posted July 5, 2016 Author Share Posted July 5, 2016 Hammer spring is a 13lb. Gun has about 18xx rounds through it. I can try to polish the hammer hooks if that is a good option, but always heard that is kind of a last resort and can end badly. Thanks all.

kneelingatlas Posted July 5, 2016 Share Posted July 5, 2016 Have you polished your trigger plunger? Changed the spring? Link to comment Share on other sites More sharing options...

Stop spreading bad information. The wing has absolutely NOTHING to do with SA break or poundage. As pointed out by KA, SA is primarily sear/hammer hooks, then spring weight. Hammer spring is a 13lb. Gun has about 18xx rounds through it. I can try to polish the hammer hooks if that is a good option, but always heard that is kind of a last resort and can end badly. Thanks all. Entirely too much spring. You'll have to run a 10# from PD or clip three coils of an EG light to get sub 2# SA. To my knowledge it is the same spring in my other guns, and it barely lights primers the way it is, so I don't know how much lighter is realistic on the hammer spring? Plunger parts have been polished and plunger spring replaced with an 18lb, yes. Link to comment Share on other sites More sharing options...
JusticeOfToren Posted July 6, 2016 Share Posted July 6, 2016 How much weight are you targeting for SA? I honestly feel little to no difference between 2 lbs 10 oz and 1 lb 12 oz on my Stock 2s. To get 2 lbs 10 oz it's fairly straightforward. I run Extreme light hammer and firing pin springs. Other than that, just excessive polishing of every metal contact surface until they are close to mirrors.
