My Tanfoglio Stock III and what I’ve done to it.


Recommended Posts

Hey guys, been on this forum for a little while now, great place for Tanfoglio advice,  it seems info is very limited outside of this site, 

 

When I bought this pistol I knew nothing about Tanfoglio other than I liked the looks of it, did not know it was a tinkerer’s special, which is totally fine with me, I love to tinker! Just didn’t think it would need as much work as it did given the price!

 

I thought I would share what I’ve done to my stock 3 since I got it last year. And a few photos in good lighting :)

 

Feel free to share and tips or advice!

 

Tanfoglio Stock III Special Edition Nickel Small frame. 

 

Added And modifications include:

 

-Henning Fibre Optic Front sight

-Henning medium flat Trigger

-Henning trigger return spring kit, 17# installed

-Wolff 7# recoil spring

-Extreme Titan Hammer

-Patriot Defense Hammer spring kit, 10# installed

 

Things I’ve done

 

-Cerakoted barrel armour Black

-Trimmed trigger bar plunger spring 2 coils

-Replaced 2 piece sear with 1 piece

-Polished plunger, trigger bar, sear, firing pin retaining plate, hammer strike face, slide rails and feed ramp also maybe more I can’t think of.

-Removed FPB

 

Coming I have a Conefit Guide Rod, PD enhanced sear spring and Henning trigger bar spring kit.

 

My load is 147gr berry bullet in front of 3.0gr of vihtavuori n310, OAL 1.101, (chamber is tight) high presssure very light shooting load, and of course Federal Primers

 

This is a 3 gun pistol, I don’t shoot IPSC or IDPA so not limited to very many rules.

 

love the gun so far, Very accurate, my trigger pull is SAO of course and comes in around 3.0 - 3.5#, I wouldn’t mind it being around 2.5#, not sure what else I can do to get it there.

I have the henning trigger set up almost perfect, but I do find the reset a tad long, but if I extend the pre travel screw any further the pistol will not reset, open to any suggestions to help me reduce the reset length! Post travel is about as perfect as it gets.

That pistol looks great! 

I run a Tanfo for limited division in USPSA. My setup is very different from yours but, my trigger breaks at 1.75 pounds.  I have a factory plunger spring. Polished the living crap out of the the entire plunger assembly and trigger bar.  Xtreme medium hammer spring, Unica Hammer, polished sear and sear cage, Patriot Defense trigger return spring, PD sear spring, PD firing pin spring, Patriot defense firing pin, extended firing pin block.  I am not at all familiar with the Henning trigger system but, based on the parts you have listed I think a good change would be the sear spring.  The factory sear spring adds a lot of weight to the trigger pull compared to the Patriot Defense sear spring.

 

Edit...

I just noticed that you said you ordered a PD sear spring.  In addition that, polishing everything should get you where you want to be as far as pull weight.

Thanks Bill! I did polish the crap out of everything, I think the only thing I didn’t do was the sear cage!

hopefullt this PD sear spring will put me a tad lower!

hammer, sear, henning trigger, 10lb main spring should be alot lower than 3.5 lbs?

 

why didn't you use the henning plunger spring that came with the trigger?

Bought the trigger second hand, it only came with one trigger return spring, hence why I had to clip some coils off the stock plunger spring, once the new kit gets here ill try each of them.

I’ll polish up the sear cage and the holes and the pin here tonight and see how that goes.

To reduce pretravel install a BOLO disconnector. Along with the Xtreme extended firing pin block and the Titan hammer, that will cause the trigger to have nearly zero travel ahead of the reset point.

 

There’s a 4-part Tanfoglio Tuning video series on YouTube I posted which shows precisely what to polish.

 

I do not find a reduced power plunger spring of any kind to be helpful or needed. Their frequent causing of odd malfunctions led me to keep that stock and polish the hell out of it’s hole and rod instead. Same reduction in trigger pull with zero reliability concerns.

Your videos are the ones I followed when polishing the parts, other than the sear housing as mentioned, which I will do here shortly,

 

My plunger head/bar are extremely shiny and smooth along with my trigger bar and contact points, I could maybe try and smooth out the plunger hole some more, 

 

With the stock plunger spring the Henninng trigger would absolutely not reset even with the heaviest return spring on the trigger, too much upward force into the trigger bar, didn’t seem to matter how smooth it was.

 

As mentioned I have the Titan hammer and have my FPB removed, I do the the extreme FPB and extreme FP but did take out the block,

 

Does a BOLO help shorten up the trigger reset then? Right now I have a some pre travel before it hits the wall before it brakes, if I try and shorten it I anymore with the pre travel screw it wont reset once the slide it on,

 

The Bolo I have available to me here is a Patriot Defence one and I’ve heard they can be a real bear to fit and install?

I’ve got no experience with the Henning trigger.

 

With a Titan hammer and a single piece sear, it should drop in with little to no fitting. Mine went in untouched and functioned perfectly.

 

reduced plunger spring is paired with reduced trigger spring in the Henning trigger system

Got the PD Bolo extreme sear and enhanced sear spring and conefit guide rod yesterday, The BOLO will need some fitting, won’t engage the sear so the trigger is dead and the hammer won’t fall, took it out and Iam at 2.5# now but still want to go a tad lighter. Fitting this BOLO seems like it will be a bit of a pain. Anyone have any experience doing this?

You are running soft Federals and I assume an extended firing pin and light fp spring, and no fp block. 

With the same set up in a CZ 75 I  :

1. Caught the end of the barrel on the top of the holster while trying to push speed in practice. In different words I started forward with the gun before it had completely cleared the holster.

2. Dropped the gun between my feet and it went off upon impact with the concrete I was standing on.

3. Cautiously inspected my feet and legs for bullet holes.

4. Cautiously inspected my car for bullet holes. 

 

For what it is worth. I think the combination of lightest fp spring + longest fp + softest primer + hard surface was sort of worst case for needing a functional fpb.
