Extended firing pin replacement

[benq]

My P-07's firing pin broke while dry firing the other day.  Naturally called CZ-USA, had to leave a VM then headed to czcustoms and Cajun GW web sites.  I notice CGW had extended FPs. Is the only benefit of an extended FP to ensure a good solid strike on the primer? With respect to CGW's FP, it is made from tool grade steel, so I'm inclined to assume it may be my last FP for this pistol. Leaning towards getting CGW's rather than an OEM replacement from CZ-USA.

Thoughts? Gotchas? Thanks in advance.

The reason to install an extended firing pin is so you can install a lighter main spring and get a lighter dual action trigger pull (and still ignite primers).  In fact if you do install the extended firing pin you must install a lighter main spring.

I have extended firing pins installed on all my CZ's, along with a host of other CGW and CZ Custom parts.  The lighter main spring is really noticeable on the DA trigger feel.  I highly recommend it.

With the CGW firing pin you can dry fire as much as you want without worry about firing pin failures (if it breaks it is covered under lifetime warranty).

I just ordered another batch of parts from CGW for the rest of my CZ's.  David at CGW provides the best parts and customer service!

Good luck!

Thanks Toby for sharing. I like how CGW offers packages eliminating a lot of the guess work for less experienced gun owners like myself. Time to give them a ring.

Installed CGW PN 97910 and chose the blue hammer spring.  Retaining pin was a bear to get in, I didn't want to use too much force. In the end, I gave it a few good solid whacks.

I have to say DA pull feels a tad different, almost lighter.

Benq,

That is the benefit for the extended firing pin and lighter 13 lb main spring.  You should still get 100% reliable ignition but with a lighter DA trigger pull.  Most of my guns went from a 10+ lb DA pull down to an ~8 lb DA trigger pull.  Couple that with internal polishing and you get a fantastic trigger pull in both SA and DA.

I'm not familiar with the P07/P09 guns but imagine they have a similar drop in DA trigger pull with the CGW parts.

Cheers,
Toby

The CGW firing pins are exceptional products made out of tool grade steel.  While you are at it, you should go ahead and get his 97910 double action upgrade package which will improve the trigger function and feel.   I put that kit in my P07 along with Dave's hammer kit and steel sight set.  The gun runs far better than stock and is a real joy to shoot.

When you replaced the extended firing pin, did you also replace the FP retaining pin or did you reuse the stock one? If you are going to dry fire it is recommended that you replace the FP retaining pin with CGW retaining pin.

The cut radius of the slot in the CGW FP that the retaining pin hits "matches" the radius of the CGW tool steel retaining pin,  so the impact is spread evenly.  The slot radius in the stock FP and retaining pin doesn't match,   so the pin gets damaged with some number of dry fires hitting in a very small spot on the pin.

For clarification, PN 97910 includes: extended FP, FP spring, FP block spring, retaining pin and two hammer/main springs. All parts were installed and I chose the lighter hammer spring. I'll try to upload an image of my OEM retaining pin. It has a big gouge from the FP hitting it several thousand times.

Is this a carry gun or one you're only going to use for competition?  I have a different opinion than a lot of people on lightening springs on carry guns, which means I won't do it.  It's true you can lighten the hammer spring on the gun and if you use an extended firing pin you will probably sacrifice little in terms of reliability; you will however reduce the speed of your lock time (the hammer will fall slower).  To be honest I doubt it matters much but I'm a perfectionist who likes to have his cake and eat it too.   These other guys are right, you shouldn't use the CGW firing pin with a full power hammer spring --at least that's what CGW told me when I asked.  However, one of the guys at CZ custom told me theirs could.  I've been using the CZ custom one for some time now in 3 of my CZ75's without incident.  I don't know which one is the better made product or if a cz custom one will fit a P07 but there's my 2 cents.  By the way, I also drink my own urine and administer electroshock therapy to myself.

I installed CGW's UltraLite / SD kit including the extended firing pin, firing pin spring, firing pin retaining pin, blue reduced hammer spring (13#) and lighter FPB spring.  I also installed their lighter TRS. 

After measuring trigger pulls, I opted to go back to OEM parts..................However, I left in the CGW firing pin retaining pin and the TRS.  Should this cause me any problems?  Will the original firing pin with the CGW firing pin retaining pin wear the pin out faster?  I didn't notice any caveats about that.  At the very least, should I not dry fire it without snap caps?  Thanks

Sorry if I highjacked the OP's thread, but this looked like a good place to put it.

  Should this cause me any problems?  At the very least, should I not dry fire it without snaps?

I will not claim the be the foremost authority on the subject but shall endeavor to be of some assistance:  I doubt you'll have any problems as far as wear is concerned.  I always try and use snap caps when dry firing my 75's but I do forgot once in awhile; I doubt it's the end of the world.

Right now, it is my carry and for the occasional IDPA matches. I chose to install the lighter hammer spring out of pure curiosity with the no intention of keeping it in for the long term. I appreciate your input and agree the lighter spring isn't generally acceptable for carry.
