Competition Hammer?

[Deetroit]

I've read here and elsewhere that one of the best mods for the CZ is the competition hammer. 

Why is that?

It easily gives you a lighter trigger pull.

Competition hammer have different, shorter hammer hooks and that gives you better trigger pull.  Its popular mod because its not very hard to change hammers on your own and you can have great trigger without going to gunsmith to recut your current hammer or sear, etc

[P01man]

Yes the most impactful single mod for the least effort and money.  In my new TS, I replaced the hammer and it reduced pull weight slightly but made it incredibly smooth and reduced required travel (pre and over) by 70%!  It makes your gun feel like a much more expensive one.

Aah, I was wondering the same thing.

So my guess has been all wrong all this time. it has nothing to do with the shape, like that outline type of look, it is the geometry of where the hammer engages the sear.  Is it just shortened? Or is the angle actually different?

Also, with a shortened hammer engagement, does that impact the life of the hammer? Should it be replaced after so many firings?

[Corvus]

Angle is more neutral too. 
Such hammer/sear engagement will wear faster but it takes many thousands of rounds for that to happen(and you would probably need new sear first, not hammer)

Just installed the CGW decocker ring hammer this evening on my SP01 Tactical.  Holy mackerel!  Single action very short reset and very light pull.  Just a little squeeze sets it off.  I'm looking forward to trying it out at the range.  It may be my imagination, but the double action seems just a bit gritty with the change.  Maybe just needs some break in or its just in my head.

The installation went well.  I'm getting pretty adept at removing the sear cage using the CGW slave pin.  The hardest part was removing and replacing the two small pins on the hammer.  They were staked so I think that made the fit very tight.  I would recommend ordering a couple when buying the hammer rather than trying to reuse the staked ones.

I've done some of the other popular mods including the reduced power trs, 85C trigger, F/O front sight, 11.5# main spring with extended firing pin, reduced power firing pin and firing pin block spring.  I haven't done any polishing other than lots of dry fire to smooth the action.  I think I'm done for awhile.  (Maybe the CGW reduced reach system later)

It's been fun and educational.  I have a much better handle on what goes on under the hood.  I'm sure the mods have improved my shooting though I wouldn't use my skill as any type of testimonial to the CZ.

This is mostly a range and game gun.  I don't carry it,  but I do keep it in the nightstand.  The trigger (especially SA) is pretty light now.  I don't know exactly since I don't have a gauge.  Does anyone see a problem with this setup as a home defense weapon? 

P.S. Thanks to all who have posted instructions on all this.  I couldn't have done this without them.

Personally,  I prefer the pistols I shoot best for home protection.
The only real issue I see is not having one either you're not thoroughly practiced with or simply with too light of a trigger in a high heartbeat situation---and I'm NOT referring to a shot timer in comp.

When my B SA was down at 2#,  I had two premature hammer drops even in Comp. use.  In a do or die situation,  I'd probably put more holes in the wall than the threat---or worse.
But that's just my failing.

1SOW, preferred weight trigger pull for a Self Defense/ Bump in the Dark? What weight trigger pull range does the competition hammer's generally provide? In the older days before these new competition hammer how did pistol smith's tune the stock hammer?

Is there a history about these "newer" hammers? Who started making these?

The hammer alone doesn't determine trigger pull weight.  The hammer gives a shorter pull without camming the hammer back first.  The hammer combined with the springs (mainspring' trigger spring and sear spring) and the friction in the action group all affect the "pull weight". 
CZCustom came out with the Competition HAmmer and CGW offered the Race Hammer later.
The original CZ 75 -- pre B )-- had a very nice hammer-sear engagement.

1Sow Thanks!

Glad I didn't bet on that.

Question, can a CZ 75 Compact (believe you own and like these) com close to the pre-B and how? Looking for an improved SA/DA trigger SD pistol with stock/un-changed safety.

Since I have your ear; which modifications where the most enjoyable/pleasing that did not require the Competition/Race Hammer?
