Tanfastic Posted September 12, 2017 Share Posted September 12, 2017 To check if the FBP is functioning here's what I did, not sure if there is a better way but I checked with Joe at PD and he said this was correct: 1) Cock the hammer back in single-action 2) Tie the hammer in this spot with something wrapped around the beaver tail and the hammer. I used a velcro computer cable wrap, but anything that will wrap around and hold it in place will work (rubber band, tape, etc.) 3) Take a punch and push on the back of the firing pin, it should NOT push in with the hammer cocked 4) Slowly press the trigger with your other hand while continuing to tap against the firing pin to make sure it stays blocked 5) At the point where you can feel the hammer break the SA shot you should be able to push the firing pin in with the punch If you can push the firing pin in with the hammer cocked and the trigger not being pressed, you do not have a functional firing pin block. If you still can't push in the firing pin even after the trigger is pulled to the point the shot breaks, you have a dragging firing pin block which can cause light strikes.

Not until you start considering a racier hammer. The repositioned hooks are the culprit, I believe. Link to comment Share on other sites More sharing options...

Hey MM, I have the ff on my stock 2: xtreme FP PD FP spring xtreme sear xtreme sear housing PD sear spring xtreme plunger PD 15.5 hammer spring i installed all these parts and polished them a bit. Luckily I did not need to fit any part and the pistol shoots fine and I can measure with a trigger gauge the improvements on what I'm doing. since I'm not knowledgeable with filing or how things should be working internally. If parts need fitting that would totally hinder me from putting it together since my knowledge of gunsmithing is minimal. So if I wanted to install a titan hammer, BOLO, extended FPB and spring. What kind of fitting would take place? Do you have a link or a DIY video. Would very much appreciate all the help. Thanks in advance im tuning my stock 2 for CCI small pistol primers ( I know I have almost everything that is xtreme. because I was relying on old threads in tuning the platform. And then I started reading more recent trigger tunes that had patriot defense optimizing stuff. So I found out late that I did not need all that xtreme parts and I was better off with the standard parts for tinkering and polishing.) should've just asked to save some mula just didn't want to get search is your friend as an answer lol Edited September 13, 2017 by Gviz Link to comment Share on other sites More sharing options...

MemphisMechanic Posted September 13, 2017 Share Posted September 13, 2017 The only things you didn't really need were the extreme firing pin and sear housing. But they certainly won't hurt anything. Polish all of that up nicely and you probably won't have to do any fitting. Link to comment Share on other sites More sharing options...

I was trying to install the titan hammer along with a stock disconnector, safety won't engage on hammer down and fully cocked but safety enguages at half cock. The sear moves up only on half cock with titan hammer . Swapped it out with stock hammer and the sear dose not move on all 3 positions and safety enguages with no problem. Went back to the titan hammer and same issues on half cock it engages the safety. Is this normal? I'm a little bit hesitant to file it down knowing that at half cock the safety frees up. Please help thanks in advance. Edited September 22, 2017 by Gviz Link to comment Share on other sites More sharing options...
MemphisMechanic Posted September 22, 2017 Share Posted September 22, 2017 (edited) You’ll need to do this until the safety/sear have just enough clearance. I recommend removing material from the underside of the sear leg - it’s far cheaper than a safety is. You are not making the tip shorter! You’re shaving down the underside so that the sear can slide beneath it! When mine was properly fit, nothing moved at all in single action or with the trigger fully down. On safe at half-cock, pressing the trigger resulted in hammer movment, but not enough to cock the gun or drop the hammer. It would simply rock a little bit. Functionally, the gun was fine and safe.

johnbu Posted September 22, 2017 Share Posted September 22, 2017 +1 on what MemphisMechanic said. You will wind up installing and removing the sear many times to get it "just right". Embrace it! Expect it! and don't rush it. The fitting is straight forward removing metal from UNDER the sear leg. Look at it when it won't engage. Mark the "wrong side" so you KNOW which to work on as it's easy to get confused when it's all apart. Or you can shave material off the "bump" on the safety until it engages. That works too, but then you can't ever go back to the factory hammer. Link to comment Share on other sites More sharing options...

Wow hahaha you guys were right when you said this thing can't be rushed. I was marking what I was dremeling using a sharpie so I know that I'm grinding the correct area. Plus it lets me know that I'm taking out material evenly. I lost count after 10 passes and reassembling. Then on the last five attempts I just said to myself I'll be here for a bit longer. And when I test fitted the safety engaged!!! Uhhhlala! I'm done time to polish and clean! This forum is full of valuable info and all you contributors I thank you again! This is my first attempt in fitting anything on a gun that required taking off material! Yahoo I did something incredible for my limited knowledge of gunsmithing hahaha! thanks again Memphis and johnbu i almost forgot to do the FPB test that tanfastic mentioned. I failed that and had to replace the stock FPB with the xtreme extended FPB. I got lucky with this part since I had purchased a bunch of xtreme parts thinking I needed to upgrade the internals that route. Hahaha wrong...

johnbu Posted September 23, 2017 Share Posted September 23, 2017 Great! Glad it worked out for you. Like nearly everything on these guns, it's pretty easy ... the second or third time. Hardest part is the start. Link to comment Share on other sites More sharing options...
Gviz Posted September 24, 2017 Share Posted September 24, 2017 (edited) Went to the range today still had some light strikes on DA from my reloads using CCI primers. Some went bang on the 2nd DA pull and had 2 that did not go bang on 3rd and 4th DA pull. Xtreme Titan hammer xtreme sear xtreme sear housing PD sear spring PD 14# hammer spring xtreme firing pin PD FP spring PD trigger spring xtreme plunger set looking at the primer it didn't make a dent on it and some are not seated well so I can't fault the gun on those. But there were 2 rounds that had the primer set flush but was not able to ignite ( with multiple strikes) and the primers look hard as hell. Used the same loads on my CO pistol a sig xfive and it ate all the ammo I fed it. Going to do a tear down and some more polishing and going back to a 15.5# PD hammer spring. Hoping for 100% ignition on CCI small pistol primer. Any tips on what I should look into regarding my parts list and what am I doing wrong?

Trim some material off the tip of the bolo and get your DA stroke DEEP. You should have not put all those extreme parts in it, but what's done is done. Also, you need to seat your primers deeper, but you did say that already... but if you want a quick fix, put a modified bolo in. I'm guessing you didn't put a bolo in because you were worried about light strikes, etc.? Link to comment Share on other sites More sharing options...
johnbu Posted September 25, 2017 Share Posted September 25, 2017 Your firing pin block may also be hampering motion of the firing pin. Have you tested it? Look up memphismechanics post on it.

MemphisMechanic Posted September 25, 2017 Share Posted September 25, 2017 (edited) @Gviz - a flush primer is a high primer. Seat them all the way down in there - measure, and look for .003” below flush (or deeper depending on primer manufacturer.) Make sure all of your rounds pass the plunk test, and then take her back to the range before you start swapping parts and dremeling away. If properly loaded ammo doesn’t fix things, look at the list from Johnbu and SoCal. A striker fired SIG will eat anything and so will the other striker-fired guns. They have all that kinetic energy to rob from the reciprocating slide, cocking then driving the striker much harder. A Tanfogilo or CZ has only the energy expended by your finger cranking the hammer back in DA, which means once you start lightening the springs they truly need match-grade ammo. Guys who came from striker Guns like myself have to learn how to load ammo with buried primers. We have no clue: “if it’s flush, it’s good!” always works with Glock and P320 and M&P. Now that I’ve gone back to the striker guns it’s nice to just pound CCI-primed ammo out like a monkey on the 650 again, but I’m still grateful for the reloading lessons I learned while feeding my Stock III.

It just so happened to coincide with our bolo run. That being said, there are mods you cam do to the bolo to get some monstrous throw in DA. But yes, it's good to sort your gat out.
