Hammer Bent?

[mwagers]

Hello All,

I noticed on my p-01 that my hammer is not completely straight when looking at it and comparing it to the slide. A few months ago I replaced the hammer with one of CGWs kits (great product btw, highly recommended). I've been shooting it since then without problems and just noticed the hammer last week.

I'm trying to convince myself that this isn't a problem but should I be worried? Also, would it be more likely that the strut is bent instead of the hammer? I new strut is $5 at cz-usa so replacing that would not be a big issue.

Just looking for thoughts on this.

Thanks

I think pictures would help you to get some answers.

Heres a picture of what i'm talking about

As long as the sides of the hammer can not contact the sides of the slide channel, I wouldn't worry about it. Can you use finger pressure to center the hammer in the notch? If so it is probably caused by there being a little slop in the hammer pin or some side to side play in the hammer. If this is the case a new hammer pin may help, if it is slightly larger in diameter than yours.

Almost forgot to mention, the decocker versions of the CZ use only one hammer hook, so with the aluminum frame being a little loser fit than the steel one, combined with the single hammer hook, that would probably be the cause of the canted hammer. My hammer fit on the Rami alloy frame that I own is way sloppier than any of the steel frame CZ's that I own. It isnt an issue as far as reliability or shootability goes, just a little annoying and it kept me from putting a competition hammer in the Rami. I figured with that much side to side play I didnt want to put a hammer in it with that short of hammer hooks.

Thanks for the reply derweibhai. I may eventually try and replace the hammer pin to see if that fixes anything. I can move the hammer by pushing on it with my finger so like you said that may be the problem. I'm probably just being paranoid because I want my beautiful p-01 to be perfect forever .

As long as it is not binding in the frame or in the slide you will be fine.
hammer strut or hammer pin will not change the orientation of the hammer.

it looks like it is sitting straight to me, just has more space on one side than the other as it sits in the slide notch. it could be how the tolerances stacked up in the frame/slide rails.

but if the gun is running fine and you see no signs of binding, excessive wear, etc. you should be good to go.

Those Cajun kits give you a great trigger don't they.

mwagers,

Mass produced service pistols have greater tolerances by necessity.  If the hammer were several thousanths wider, or if you shimmed the hammer, it would be "centered", which your pistols condition.  Replacing the hammer pin and/or the strut would not center the hammer.

If you checked numerous CZ's, you would find most of their hammers will not be perfectly centered.

There are some other interesting tolerance variations I have seen on some CZs  that might give some nightmares

LOVE the trigger kit. Everyone should get one if they dont like the trigger on their CZ. Easy to install and great results. I've had people at gun ranges pick mine up and ask me what I did to make the trigger so nice .

I dont want to know...lol

I measured a couple of frames for the hammer cut-out, got .323-324".  Measured a couple hammers, .314-.315".

If you have a .324" frame and .314" hammer, you have .010" total side to side play, therefore the hammer can "move around" on the hammer pin somewhat.   

Also, looking at the pic, the top of the slide cut out near the top of the slide doesn't look square, but it could just be the pic or the angle.

Your right its not square. Neither is the hammer on the firing pin, or the sights either I dont think. I've actually got to adjust the sights a little. Anyone have a good way of moving the back sight without causing damage?

Brass or bronze punches work pretty well, I have also had good luck with a 3" long lead wheel weight. I straightened the weight out with a hammer and used it as a soft punch. Sight tools are quite pricey, but on the other hand so are tritium sights, and CZ sights tend to be fitted very very tightly, a punch may not move it. Are you hitting point of aim? If so leave the sight alone.

No i'm actually hitting to the right. Just slightly to the right but consistently.

support the slide in a vise...so the sight when struck takes the force and the slide moving doesn't bleed off the energy of the strike.

I use either a brass rod or a delrin punch..
or a buddy of mine just made me a set of these cool sight bashers..one has a brass tip, the other two are some sort of high impact plastic...so far they work great.

where can I get some of those??
