SP-01 roll call

[hags]

The EGW sear definitely requires fitting if you're going to use it on a CZ since it is made for an EAA Witness.

I have talked with George at EGW extensively about the sear. It is extremely hard, however the angle matches that of the hammer they sell and can be used on EAA guns without further fitting or stoning.

These are made with the EAA Witness in mind. I cannot see why you'd feel the need to screw with the stock Elite Match trigger pull which is excellent out of the box.

MYMilitiaman,

Hags posted the correct website for getting the right parts. I tried the "home trigger" job and it worked pretty well, but you will have a hard time getting the positive camming in SA alleviated.

If you do get the camming to stop, the sear may not reset if you decide to partially pull the trigger, then decide not to fire. The sear can be precariously perched in the very edge of the hammer hooks. Not good.

I decided to spend a little money and get an absolutely first class trigger mechanism. I wish I could say even more positives than I already have about the CZ competiton hammer. To achieve a truly outstanding trigger, all you need is:

1) CZ competition hammer, $58.00
2) 13 and 15# mainsprings, about $4.00 each
3) Some quality punches and a little mechanical aptitude

This is a big part of how the Angus Custom Shop achieves such remarkable results. The difference is simply amazing.

I am so pleased, I ordered the competition hammer for my new 97B.

usually if you recut the hooks..you will cut the angle out and shorten the depth. to not let the sear creep on the hooks. so when you put the set amount of weight on the trigger, the sear moves and the hammer falls..

what can happen and usually does, when you cut that depth, you cut enough off that the disconnector will not slip past the trigger bar, and the hammer will not fall in single action, but get caught on the trigger bar . then what happens is the wings on the disconnector need to be trimmed to allow the disconnector to go by and the hammer to fall. Doing this also will shorten the DA stroke of the gun, but it will feel slightly funny.

What the CZ Custom hammer from Angus allows is you to mate the sear to hammer hooks without changing the timing of the disconnector and triggerbar interface. which is very cool.


On George's part..He rocks..the hammer he has done mimics the work he produces on the Koenig hammer for the 1911 platform, George's sears are the ones to get in any gun.

It requires about the same amount of fitting for a Witness.

 

[burningsquirrels]

"george's sears"?

 

[atblis]

EGW >> Evolution Gun Works

Used to do a decent amount with Tanfoglios. I don't think they do any work anymore on the Tans, but still sell a few parts.

 

[burningsquirrels]

ah, yeah... i saw the eaa hammer they had on their website. looks wild.

 

[lysander]

Regarding the "boat anchor" comment...

I did say it was "kind of a boat anchor..."

 

[schmeky]

eerw,

I have the greatest respect for your experience and knowledge on CZ's. I had the problem you described in which the hammer would catch on the trigger bar, rendering the gun DA only.

As you know, the CZ competition hammer solves this problem handily. As far as using a Witness sear from EGW, why? A new CZ sear is only $9.00 + $4.00for shipping, but you do have to fit the sear's safety tang.

 

[hags]

That is incorrect. Basically you have to file off one side of it for it to fit into a CZ. You have to modify it to fit a CZ.

 

[atblis]

Huh

That is incorrect. Basically you have to file off one side of it for it to fit into a CZ. You have to modify it to fit a CZ.

That's odd. I don't remember having to do that for any of my CZs.

As far as using a Witness sear from EGW, why? A new CZ sear is only $9.00 + $4.00for shipping, but you do have to fit the sear's safety tang.

CZ Sear = butter
Soft in other words. I think their hammers are also soft.

You have to fit the arm that engages the trigger linkage and the arm that engages the safety lever. The arms are oversized intentionally so that you can fit them however you want. You have to do the same fitting for a Witness. Trust me, I've used the same sear in both CZs and Witnesses.

I love George's sear for 1911's and for the Tanfoglio..
I have cut CZ sears with just the one angle, with a secondary angle, I don't know how many ways..and truthfully have had no problems with them losing their angle..

I am just working up an order for George..to get a couple of sears and a hammer..one to try in the TS and one to see how it fits up in the small frame..


truthfully, I just love playing with stuff..for no other reason..because..

 

[burningsquirrels]

let me know how the egr hammer works. it looks cool, lol. i can toss my current cz comp hammer in my fiance's sp-01.

 

[atblis]

I can't seem to remember, but what are the difference between the Tanfoglio hammer and a CZ hammer. I am thinking the pivot pin hole is larger on the Tanfoglio.

 

[burningsquirrels]

i thought being a clone of the cz, there were many parts that translated over...? but i've never seen one apart, only exploded diagrams.

 

[GZOh]

burningsquirrels... I take back everything I said about your fiance and your priorities...
Any gal that has, and shoots a SP-01 is a GOOD WOMAN!... Good luck with the wedding and many years of a happy marriage!

 

[burningsquirrels]

lol, is that all it takes, an sp-01? haha!

 

[GZOh]

That, and if she's a GOOD COOK... that's all ya need!!

 

[vogski]

Well

i thought being a clone of the cz, there were many parts that translated over...? but i've never seen one apart, only exploded diagrams.

The sear and a spring or two are the only parts I can think of that are pretty much interchangeable. The hammer IIRC has a few minor differences. I think the pivot pin is larger. My Series II stoning jig thingy for the Tanfoglio hammers doesn't fit CZ hammers. The pin is too large.

I am pretty sure the hammer can be made to work and that somebody did it over on Czforum.com

The early Tanfoglios are more Czish than the newer ones.

It used to be that the Tanfoglios had more aftermarket than support than CZ and more people gunsmithing them. Under Springfield they had a pretty good following (see Springfield P9).
