If you want to run a stock 2, you will probably screw around with a few spring weights. The recoil spring (obviously) needs to get messed with. The hammer spring will get messed with. A 13lbs spring will work fine... if you adjust the firing pin. The henning pin that works with the firing pin block is the pin that is best at popping stuff. That is the pin to buy. You don't need to buy any other shit if you don't want to. If you polish stuff you should get a decent trigger. If you buy all the EGD stuff and fit it properly you will probably get a better trigger.... but not by much. I do not recommend buying the EGD stuff.... but if you want it I will sell it to you.
A lot of headway has been made in the last year. Hands down the best product on the market for USPSA shooters is the new henning pin that works with the firing pin block. If you rock that your gun will pop stuff pretty good.
Visiting 'Ben's Corner' in the pro shop yields a clue:
Only one Tanfo part (aside from the basepads) featured: Dat Firing Pin from Henning
Original Post pre Update
Seems to be sparse info on tuning Tanfos.
DYVG has a ton of info in his diary thread and there's some info on Enos.
Why shouldn't Doodie have the best info available?
So what if you have a Tanfo and have tuned it - post the model, work you've done or have had done, and the results.
I just bought a Stock III and a CZ SP-01. I put a few hundred dollars in CGW pieces in the CZ and it's really really great now.
I'm not sure what to do with the Stock III. I don't want to swim too deep in the light primer territory.
