cpa5oh Posted January 28, 2014 Share Posted January 28, 2014 I'm probably going to end up sending this gun off to a gunsmith that works on these, but I took my shot at throwing some parts into the Stock 2 to see how good I could get the trigger. After installing the Extreme hammer, my safety is no longer operable. With the hammer cocked, the safety leg of the sear is flush up against the safety "nub" that ordinarily would rotate to the rear of the gun to stop the sear from rotating forward when the trigger is pulled (with the safety in the off position...so there's no way for the safety nub to move to the rear of the gun.) It's as if the sear is rotated up on in the rear by the hammer and down in the front. Anybody else install an Extreme hammer and have to deal with this? Feels like I have to be missing something... Thanks! Link to comment Share on other sites More sharing options...
kneelingatlas Posted January 28, 2014 Share Posted January 28, 2014 Fitting the safety is a part of the game when installing a new hammer or sear. Link to comment Share on other sites More sharing options...
cpa5oh Posted January 28, 2014 Author Share Posted January 28, 2014 I think this goes beyond being a "fitting" issue...when I cock the hammer, the sear leg for the safety does not rotate up and to the rear at all - I thought the sear leg would go up and to the rear to make room for the safety 'nub' to move to the rear and keep the safety in that rotated up and to the rear position. I'll try to post a picture tonight. Link to comment Share on other sites More sharing options...
kneelingatlas Posted January 28, 2014 Share Posted January 28, 2014 I can visualize what you're saying. The hooks are much shallower than stock on the new hammer, so the safety leg of the sear and/or the safety nub must be grind down to the point that the safety will engage. Just make sure this is the combination of parts you want in this particular gun, because if you're still changing things, you may need new parts.

Nealio Posted January 28, 2014 Share Posted January 28, 2014 Yes you need to re-fit the safety when you install the Extreme hammer because the platform in front of the hooks is much higher on the Extreme hammer. I was surprised how much material I needed to take off the safety leg. Link to comment Share on other sites More sharing options...
cpa5oh Posted January 28, 2014 Author Share Posted January 28, 2014 You two are the best! I am in both of your debts...now I gotta figure out whether I have the balls to take the project on myself or send the gun out...if I could get the DA pull under 8#, the SA at 2.5#, and the reset shorter than a country mile I'd take this on and try it. Lemme see what I can do about those things and if I can get them done I'll go to work on the safety leg of the sear... Link to comment Share on other sites More sharing options...
cpa5oh Posted January 29, 2014 Author Share Posted January 29, 2014 I successfully fitted the safety tonight based on your recommendations. I figured that if I screwed up the sear I'd just get the one piece sear...but I took material off of the sear leg that the safety gets in the way of and the safety now works. And the sear looks like it functions normally now (rather than looking like it was getting stuck when it was rotating forward.) Still have the 8# DA and 3.5# SA, but it certainly feels better with the Xtreme hammer properly installed. I've got an interrupter for a CZ coming to try and get rid of the pre-travel in the SA mode. And then I'll get after the reset legs of the sear (looks like I might have two legs to deal with on this Stock 2, whereas there was only one with the Limited.)

BeerBaron Posted January 29, 2014 Share Posted January 29, 2014 if your getting a CZ disconector to reduce SA pre-travel (and reset) then get the "pre-b" one that CZC sells or the "SRS" one that CGW sell. I'm not sure on fitting one into the stock II but they certainly work great in my CZ. Link to comment Share on other sites More sharing options...
cpa5oh Posted January 29, 2014 Author Share Posted January 29, 2014 I have the CGW gunsmith fit one that is coming...maybe it'll turn out I need to get the other, I don't know. I just figured that, if gunsmith fit, it'd probably work with fitting...we'll see what happens this weekend. Link to comment Share on other sites More sharing options...
kneelingatlas Posted January 29, 2014 Share Posted January 29, 2014 CZ discos utilize smaller pins than Tanfo so any disco make for CZ will need the pin holes drilled out. The Gunsmith fit disco from CGW has the best chance of working for you as I think the pre B one CZC sells has a smaller wedge than the stock Tanfo one.

cpa5oh Posted January 29, 2014 Author Share Posted January 29, 2014 Yeah I knew the disconnector pin hole was going to have to be drilled out - the stock Tanfoglio one is very loose sitting inside the hammer, so I don't imagine that I have to have a perfect fit. Hoping it works out - it's enough trouble for me shooting a DA/SA gun, all that pre-travel in SA mode fouls me all up...I suppose I could get used to it, but I like to shoot alot of different guns so I don't get settled on one for years at a time...

BeerBaron Posted January 30, 2014 Share Posted January 30, 2014 yeah the SA pre-travel sucks and is really unnecessary. hopefully the CGW gunfit disco works for you. Link to comment Share on other sites More sharing options...

Xander Posted March 1, 2014 Share Posted March 1, 2014 I got the PDF file too from Eric, but it is not clear how and where exactly should I take off the safety side of the sear. I hope somebody could post here what they did? Thanks. Link to comment Share on other sites More sharing options...
cpa5oh Posted March 1, 2014 Author Share Posted March 1, 2014 You just shorten the top, left (when looking from the back of the gun, as you would when shooting it) leg until there is room for the safety to go all the way through its travel.

Prov1x Posted August 24, 2014 Share Posted August 24, 2014 Bump this up since it contains the pdf file for fitting the sear to the safety. Not in detail but at least there is a pic of it. Link to comment Share on other sites More sharing options...

hercster Posted August 25, 2014 Share Posted August 25, 2014 I just went through the same experience. A friend is trimming the sear leg for me. Now with this experience I will be able to do it myself if need be. The transformation of the gun is quite remarkable. Thanks to all for the help.
