Truckin_Thumper Posted April 4, 2019 Share Posted April 4, 2019 Well, this is the second non CZ pistol I have owned in quite sometime. All I have done is about 35 rounds out of to function test it before I start in on making it for Carry Optics. Seems like an 8lb recoil works well with 150gr subs, 115gr store bought ran pretty well too, only one FT Feed, chalked it up to new gun and all. That said, we are going to focus on weight. I also picked up a Delta Point Pro we are going to stick on top. If my scales were off, this thing stock with mag is 44.5 oz. That leaves me .5 oz to play with and a 2 oz optic. I assume the rear adj sight is close to 2 oz? I dont know, Front cant weigh crap, but it will come off too. What else can be done to reduce about 2 oz? Also, I have some new hammer springs coming in to try and get the god awful 8+ lb DA reduced. SA is almost 4, which sucks too. We need the DA to sub 5 and the SA as low as we can.....2 lbs would be about perfect. Link to comment Share on other sites More sharing options...
Posvar Posted April 4, 2019 Share Posted April 4, 2019 Are you saying it’s 44.5 without the optic? The rear adjustable sight weighs next to nothing. Front is a couple grams. You will need to lighten the slide most likely. Link to comment Share on other sites More sharing options...
Posvar Posted April 4, 2019 Share Posted April 4, 2019 And you need to make sure that you can make weight with a magazine with the extension that you need. You don’t want to shoot with a 17 round magazine. Link to comment Share on other sites More sharing options...

Je85 is right 5.5# DA and sub 2# SA with just these parts. I have spent hundreds on hammers and spring and stuff to find out that's all that was needed.

Install a single piece sear and otherwise focus on polishing INTENSIVELY and re-springing. 35 minutes ago, Fo0 said: PD BOLO No. The bolo deletes some pretravel which doesn’t really matter although it feels sexy... but it also causes your hammer to travel less before it falls in DA. There are ways to remedy this but it requires time and patience, and probably wrecking the first BOLO to see how far back you can get the hammer travel before you’ve removed too much material. The bolo is a solution to a nonexistent problem. There’s nothing wrong with a bit of pretravel, it doesn’t affect your shooting speed or accuracy.

No. Run the factory firing pin. If you go back through the forum with the search I spent two full days testing every combination of spring and extended vs stock firing pin. The aftermarket pins launch a pencil slightly higher but show zero actual improvement in setting off brand X primer with brand Y firing pin. Run the stock one.

MemphisMechanic Posted April 4, 2019 Share Posted April 4, 2019 Weight removal: Patriot Defense lightweight guide rod. Lighter grip panels. SSI Scales, or one of the plastic options out there. There are several good threads on grip panels showing sizes and weights. Search for “tanfoglio tuning” on YouTube. I did a 4 part video series on teardown, polishing, and reassembly.

It shortens the trigger travel. Reduced pull weight comes from springs and polishing. You can get a Stock II down to 6.0-6.5 & 2.5-3.0 pretty consistently with all factory internals (including the two piece sear) with springs, a lot of patience, and a dremel. Guys were doing it for a full decade before shiny hammers and special disconnectors started appearing. Nationals and the World Shoot have been won a dozen times cumulatively with guns set up just like that. These guns don’t need a lot of work. We just like to tinker and tune them because we enjoy the challenge of seeing how far we can get things. Warning to the OP; CZ triggers are usually better than Tanfo ones with a similar amount of work invested. The much longer hammer spring has a lot to do with that. But +/- one pound of pull weight only matters when testing it on your workbench. A clean crisp 2.8lb single action and glass smooth 6.5lb DA will shoot just as fast and true as a 5/2 trigger does.

I am saying is you suggesting to lower trigger pull weight like it is a great benefit but reducing the travel of the trigger is not worthy. You state one " doesn’t really matter although it feels sexy" and trigger pull weight is different. Link to comment Share on other sites More sharing options...

Shortening the travel isn’t actually an advantage on match day. It just feels better on the workbench. Otherwise the guns with zero overtravel and zero pretravel would be winning matches due to the inherent advantage. They’re not. It doesn’t work that way.

I would agree 100 percent....took the over travel screw out completely and took more off the BOLO to induce more pretravel. I personally like about 3/16" of pretravel.

Truckin_Thumper Posted April 4, 2019 Author Share Posted April 4, 2019 You all answered some questions I had and assumed the correct answers.... I am ok with the longish pull on DA, the 8+ lbs, hell no! I should have a bunch of springs in today so it will get torn apart and polished up tonight. I gotta weigh a bunch of parts to see what I can do to shave off an ounce or two without having to start milling the slide (outside of the DPP). I will take pics of what weighs how much as I do this. May help the next idiot like me that wants to do things the hard way Link to comment Share on other sites More sharing options...

You‘ll go from 12.5 down to 7-8 with springs, depending how light hammer spring is. From 7-8 down to 5-6.0 pounds with polishing. The bolo is easy to fit. It just doesn’t do anything except shorten the single action pretravel. If you like that? That’s *great!* Enjoy it. But it isn’t necessary to win matches with a Tanfo. I know of at least 8 GMs who shred in the overalls with a Stock 2, and none of them run a bolo. The bolo doesn’t reduce your trigger pull in most guns. Sometimes a little, usually none. I have this attitude because I consider BOLO & Titan hammer to be the one upgrade to my Stock 3 that I wish I hadn’t done, and I’m not shy about admitting it. Like @JayTac556 I would have added some pretravel back into the bolo setup if I had kept the gun. Edited April 4, 2019 by MemphisMechanic Link to comment Share on other sites More sharing options...
