Bummer! Thanks. Guess I will wait for my new grips to come before I shoot this gun anywhere other than club night....
16.1 Modifications to them, other than minor detailing (the removal of burrs and/or adjustments unavoidably
required in order to fit replacement OFM parts or components), are prohibited. Other prohibited
modifications include those which facilitate faster reloading (e.g. flared, enlarged and/or add-on
magwells, etc.), changing the original color and/or finish of a handgun, and/or adding stripes or other
embellishments.
I interpret the handgun being the frame/slide.
Also, you are permitted to add grip tape to your gun. Can be argued that you applied liquid grip tape in the form of slippery paint to your factory grips!!
In my eyes you are good to go with the painted grips as they give you no advantage other than a psychological one (cause your pistol now looks high speed and low drag!), but then again, I'm not making the ruling at the match if it were to come up.
Just shoot it and have fun.
There aren't any level 3 matches until next year.

I have a very light trigger and was using Wins but even with Feds there are still issues. The gun has all the mods so it's the design of the gun itself which makes having a light Shadow type trigger difficult (this is coming from a few gunsmiths).
Your primers are still not seated 100%.
Come to the club tonight for ppc, you get free admission, I have a 100 rounds for you. If mine don't go off they are free, if not $15 for the ammo. That will answer the question. Give me a call.
I don’t think it will be beneficial to bring it under 6 lb in double action, I know it could be done, a combination of light springs /polishing /lowering the hammer hooks certainly could make a difference but again all this will be worth nothing if it fails to fire reliably .It also will be shortening the life of the trigger job as with use you will start to have the hammer following the side. There is a limit to how light you can go on the springs including the trigger spring, to light and the trigger will fail to reset or it will be slow to reset at least which certainly does not help.
I'll give you a call buddy hehe (free ammo makes me smile since i'm running low). babo_al the gun was great when I got it from you but as anyone who knows me I like to push the envelope to full retard (Tropic Thunder reference), good news is I can always go bring it back to where it was. For now i''m just trying to find that sweet spot of reliability with a lighter double.

I had a chance to mess around with the OP's gun yesterday. The trigger was indeed pretty stiff and what I like to call "crunchy". It's pretty nice now though. The DA stroke is not ever gonna get to 6 lbs.(this design won't support that and remain reliable), but it is now very smooth and consistent, which is far more important than a light pull weight.
These are REALLY nice guns.

You are very humble! "Pretty nice now" is an understatement! Thanks again!
So I took Perry Wood up on his offer of a free 100 rounds and yep he was right again (one day I shall proove him wrong with something!). Now I owe the guy $15 next time I see him! 100 of his Federal hand primed rounds worked flawless in my gun with the very light double I have. The issue is that my 650 wasn't seating them as far as his hand primed ones. I'll see if this can be adjusted and now it's time to get my gun closer to 6lbs and reliable. My old Shadow was 5.03lbs double and reliable so I figure even with the Tangfo's different design 6lbs can be reached.
6lbs may be doable,..but at what cost. IMHO,..smoothing outweighs the weight. I would rather have an 8lb smooth DA than a 6 lb iffy one. I have felt some tanfo triggers that had wobble ind DA and felt chauky. I would estimate mine in the 7.2lbs- 8lbs DA range and works with OEM parts,...and is smooth. ONe thing I don't support is bending or tweaking of the trigger return spring too much. You want a fast and reliable reset. I had a bent spring in my stock 2, but did not like it. Felt too slow to reset. I chucked a new one back in and could not be happier. The sear spring could be torqued a little to relieve new spring tension, but not changed or cut in any way.
My ammo is all Canadian BDX ammo, reliable and I believe made with winchester primers.

Right. And you can't cut the mainspring either. It will destroy the spring and take you out of Production...technically. Try assembling the gun with the sear removed (install the cage only) and stroke the D/A. The sear return spring accounts for very little of the total pull weight, so this will show you what you're really dealing with. Your trigger return spring will account for some of the pull and the rest of it comes from the mainspring. A 13 lb mainspring should give consistent ignition with most primers, but lighter than that and you're pushing it. If you "over-tune" the trigger return spring you will end up with a flaccid feeling reset, and you'll be constantly trigger freezing.
Note that the Tanfo Mainspring is a lot shorter than the CZ's. As such, as it gets closer to maximum compression it stacks up (increases) markedly just before the hammer is released. This sensation is exacerbated by the contact area above the the hammer hooks which drag across the underside of the sear, and by the nodes on the bottom of the cage which push the D/A interrupter bar out of engagement with the trigger stirrup to fire the gun. These areas can be polished for smoothness and the sear spring can be tweaked a little to reduce drag pressure. Grease rather than oil on these surfaces improves feel considerably.
Cz mainsprings never get close to maximum compression so the stacking isn't apparent there. Note also that that sensation of stacking in the Tanfo can be used to your advantage, since you end up with essentially a 2-stage trigger. So on your first shot you can take-up to the stacking point on during the last few inches of your target acquisition, then once you get your visual confirmation of an acceptable sight picture you can pull the rest of the way through. Very revolver-like.
