The problem is the lack of consistency in the pistols themselves.
Completely agreed..... but for the sake of this thread we can at last see what he comes up with as he's done a pretty good job gathering data.

Most people I know are changing springs every 2,500 to 3K.
My "Match" gun for sure doesn't go over 5-6K, my practice/Dryfire gun..... probably 8-10K

All good with me - keeps the information all in one place for later searching.
I'm planning to do something similar too. See how a PD 14, Wolff 14, and E.G. Medium compare in the pencil test. Compare the standard and Patriot heavy firing pins too.
Hopefully I feel motivated to play with it tomorrow.
Memphis, ill get you the hammer springs your missing in the mail this week. It'll help everyone out seeing the consistency from one gun to keep the constant standardized.

...Although many of us who shoot a lot are going to wait a little longer than that...
I always re-sprung my comp gun once a year, in the spring, before the season started. With the Glock and M&P that was sometimes 12,000-15,000 rounds.
Respringing a gun every 3 or 4 months if you shoot in high volumes seems quite excessive. I honestly don't know anyone who resprings more than 2 times a year with a 2011 or Production gun no matter what number of cycles the springs are seeing, and that works well for them.
You need to pay a little bit more attention to that hammer spring, sear spring, and trigger return spring. They will leave you wishing you had changed them out at the worst possible time for you...... I understand not doing the whole gun, i actually prefer some springs to loose some weight....... I wont chance a hammer spring, sear spring, or trigger return.

I went and made a cart full of all the stuff you need EXCEPT FOR the extended firing pin block. Out of stock, apparently
====================
We have qty-55 on the way
.... If customs doesn't hold things up should have them at the end of next week.

At the Grauffel webshop you can only order recoil springs in different lbs and they are 140 mm. Nothing like long slide or 120mm standard slide.
So I guess you have to cut coils if you don't have a long slide to get the 120 mm.
But is the recoil spring than still 10 lbs if I cut coils? Or do I have to take a stronger spring to cut coils?
If you cut coils your changing the spring rate........ making it softer

What do you estimate the cost at for new internals.
Springs run you about $40, Sear is around $35, Xtreme FPB $15, Titan Hammer $112

How often do you change to new springs
its recommended to change out springs every 5,000 - 8,000 rounds.

It is normal for your interrupter to touch the ramp on the frame, however if it contacts it to much it can cause your sear to sit off of the hammer hooks. Are you having any issues or are you just wandering if thats normal?

i would like to have that gun tested for performance enhancing drugs.......

Based off your order your ready to wage war on that thing
......... It'll ship out first thing in the AM.

I've read through your thread and all the pictures. My safety looks like it's hitting on the very tip of the sear not underneath. Like my sear is too low even though everything is in place and installed properly. Everything I've read says don't file the tip of the sear leg. Which is where mine looks like it's hitting. Of course I could be wrong too because it was a long day for me and I was tired. I'll be waiting for new sear springs before I do anything though
pictures speak a thousand words........

I bought this S2 used, the first owner has fitted the disco, I will find the threads and do more work on it. I changed trigger bar plunger spring to the bic pen spring , is that good?
Loose it, that's your problem right there.

I have a Stock 2 with all polished and fitted extreme parts , T3 disco and reduced power trigger reset spring. Now the DA is 5lb 5oz, SA 2lb 3oz, which is very nice, but the only problem is the SA reset is not positive. Sometimes the trigger will not reset before my next pull, usually happen when I double tap or drill. I use "reset riding" trigger control and keep my finger in contact with the trigger at all times, so that's may be the reason for not reset. I tried a heavier trigger reset spring, that will temporarily solve this problem but make DA 6lb, SA 3lb, but lighter trigger is better. I heard there is a way to polish the T3 dicso to get the positive reset, anyone knows how to do that? Or is there any other method to solve this problem? Thanks a lot.
You need to fit the disco, there are several older threads on here that discuss in detail what areas to hit.
You havent changed out the trigger bar plunger spring have you?

You're making me want to do a "pencil launch test" with those two side by side...
Remember the EG medium is marketed as a 15.5lb spring as well........ I need to find the sample pack of 15lb springs i did up........ It seems like there may be a market for 15lb PDO hammer springs.

A "slow" pull can mean many things. It may mean a pull that stops the trigger as soon as the hammer drops. Tanfos NEED a FULL STROKE of the trigger. Fast slow or medium ... if the stroke is stopped (or slower ) as it drops the hammer, there are a couple "bad things" that can occur. First is the sear may not have lifted the fpb fully. But, the sear being just barely lifted can also allow the 1/2 cock hooks to impact the sear face. testing trigger pull by the old style hanging weight method and adding just exactly the amount to dtop the hammer will show this. Another thing is the disco "wing" can slide off the trigger bar erratically giving variable short hammer drop.
Funny you mention the 1/2 cock John as i was just chatting with Waktasz this morning about this phenomenon. Some guns on a really slow SA pull will either fall to half cock or graze by it which in turn slows down the hammer greatly. Now i know he's having issues in DA but its possible he's grazing the half cock killing his hammer travel speed. I've seen some tanfo's that have a slight bit of play in the sear housing to frame tolerance that cause them to wiggle around enough for the hammer to fall to 1/2 cock. This however is seen more in the older style guns.

Interesting. The Wolf 14 feels terrible to me. I have to cut a coil to get it not feeling like it stacks horribly, and even then it still does. I wish you'd have tested the EG light spring too.
I think the issue with Wolff are they tend to vary in OD and length slightly. This may not be a cause for concern when looking at it with the naked eye it does however cause issues when the spring is under compression and the OD grows enough to contact the pocket wall. Hence why when you cut a coil or two the stacking goes away some because your releasing some of the pre-load from the spring.
2 hours ago, ARy said:I've been thinking how to better explain this -
You can pull two different brand springs. They can pull the exact same weight in DA and SA... but the strike force will be different. Ie. a PD 12# will hit harder with a similar or lower pull weight than a different brand. Because the PD does not colapse, allowing the actually spring weight to be transfered to the release of the hammer, resulting in a better strike.
So without a tool to measure collapse or compression, it's kind of hard to compare hammer springs. And I say that across the board, not just with PD springs.
To elaborate a little more on this, we choose a material that has a higher natural frequency which in turn gives you a faster response (spring returning to its normal state). This is why the majority of guys could drop down 1lb or more with our springs, they just want to return home faster which in turns gets that hammer moving quicker......

You are right Joe.....But I've been monitoring the work done by having daily phone conversations lol. (although I always vouched for the owner to do the work himself) ....... I told him to fire only in DA since DA is weaker just as an experiment (SA is never been an issue)
Knowing that you guys are the BEST gunsmiths I post here to hear your opinions

NO worries, we're all here to help out. As you know attention to detail with these guns are a huge part on the tuning process. Its easy for another competent gunsmith to look over an area because its not a cause for concern in another firearm platform.
-
Based off my phone call with this individual he's always caught the occasional light strikes with the gun. He did not perform the work himself so it's hard to say what exactly has been done or fitted in the gun. I'll be making contact with his gunsmith shortly to discuss what has been done on the firearm.

^^^This makes sense!
My LP with a very minimal polish job and the following:
Reduced power trigger return and sear spring
titan hammer
bolo
12# hammer spring
Last night I was getting just over 8# DA and just over 3# SA.
I left the hammer cocked over night and tested the pulls again this morning.
Just under DA 8# (7lbs 10 oz 5 pull average)
Right at 3# SA (can't remember 5 pull average want to say around 3lbs 1 oz)
So, it's not apples to apples since these weren't done in MM's S3 with the polishing.
Seems to me the polishing makes the most difference. Springs may lower the DA pull a little but just slightly lower the SA(if at all)
Am I on the right track?
polishing makes a huge difference, what drove me to create new hammer springs was to get rid of the stacking towards the end of the pull........ Dont get me wrong, hammer springs will affect pull weights in both DA/SA but your big difference comes from polishing. Friction can be fun; but not in a tanfo........

John, you need to move somewhere warm so you dont have so much time to polish your guns during the winter months.......
