jmbaccolyte Posted August 20, 2013 Share Posted August 20, 2013 My Match's hammer (with the stock spring) seems to hit with more force than is necessary and I was wondering how much a lighter hammer spring would effect the trigger pull weight. Also, if I remove the firing pin block and use Win primers, what weight hammer spring should I try first? Link to comment Share on other sites More sharing options...
kneelingatlas Posted August 20, 2013 Share Posted August 20, 2013 The hammer spring has little effect on SA pull weight, polishing internals, a CGW reduced power trigger return spring and light trigger plunger spring are much more effective. With the hammer spring you could go as light as 13# and you shouldn't have a problem although it will give the break a mushy feel. I run an 18# spring for a crisp break and a snap of the hammer.

Are you using a stock firing pin or an extended one with the 13lb? I couldn't get CCI's to ignite with anything less than a 16 and the stock firing pin.

kneelingatlas Posted August 20, 2013 Share Posted August 20, 2013 Stock FP and spring although this ammo was BVAC and I think they use Federals, plus I have a TS hammer installed on that one fwiw (I guess I should weigh some hammers next time I get the chance).

RNA Posted August 20, 2013 Share Posted August 20, 2013 How do you feel about that bvac ammo? Accurate? Reliable? Link to comment Share on other sites More sharing options...
kneelingatlas Posted August 20, 2013 Share Posted August 20, 2013 How do you feel about that bvac ammo? Accurate? Reliable? I fired roughly 2K of them before I started reloading and never had a compliant; super accurate with soft primers. Two years ago I was getting 9mm for 10¢/round and 40 for 13¢. The 40 is a little hot (180-185pf). Link to comment Share on other sites More sharing options...
RNA Posted August 20, 2013 Share Posted August 20, 2013 Good to hear. They're usually one of the cheapest on gunbot (nowhere near 10 cents a round, though!), so i was a bit leery. I think I'll give them a shot and buy some 147 gr for practice since i carry 147 for self defense. Link to comment Share on other sites More sharing options...

Thanks. Is the 18# hammer spring the stock one? Edited August 23, 2013 by jmbaccolyte Link to comment Share on other sites More sharing options...
Mo Hepworth Posted August 23, 2013 Share Posted August 23, 2013 factory is either a 16, although i believe recently my stock 3 had a 15 lb. a 16 produces an 11lb da. going to 15 makes it a 10,,,,14 makes is 9...13 makes it an 8. ----roughly...with no polishing.

kneelingatlas Posted August 24, 2013 Share Posted August 24, 2013 The stock springs seem to be in the 16~17# range, I've found the best way to determine relative spring weight is to measure coil diameter; I don't know what rating they all are, I just know this one is heavier/lighter than that one.

GunslingerDK Posted August 25, 2013 Share Posted August 25, 2013 I have 3 Stock II's, I'm quite certain they come with a 16lb spring. With primers of normal hardness I run a 15lb and extended FP. But they are not good for more than 10.000 rounds then the spring needs replacing. With federal primers you can go down to 14lb. Haven't tried the 13lb. By the way, if you want a really good crisp none-creep SA pull on the Stock II you need the old one-piece sear and the Xtreme hammer from Eric Grauffel.
