How to Tune, Smooth and Upgrade the P-07/P-09 (Discussion)

[Litshoot]

So it's locked now and cgetting cleaned up now, but I have a question from page one, they explain the drill bit being used as a sanding drum, but never say what they send with it

Is it the the inside where the trigger goes, hammer goes, do they smooth pin holes, I'm not really sure where I'm supposed to go with that. My first attempt on my p07 I did nothing inside the frame, but my p09 I'm hopeing to make as perfect as possible, so curiosity took over fear.

I believe it is "anywhere that you can't sand on a flat surface".  I did as much as I could on an extra fine stone.  Personally, I would not sand anywhere I cannot see where I am sanding, but that's just me.

I'm ordering some stones for the hammer slot and I guess where the trigger goes also, but the mention directly. Using a drill bit with sandpaper as a potential flap disc or whatever it could be called.  That's where I'm curous.
Also i seem to have a habit of my finger touching the trigger housing so I tried to polish that as well, not sure if that will make any difference, I found when lightly slidding the edge of my finger across the bottom of the guard I had best results for hand position, less sight movement, Better recoil control.

Litshoot, it?s not a drill bit. It?s a dremel bit, like the one that holds a cutting wheel. Remove the screw in the end and add the strip of sandpaper with O ring to hold it on. Use the flat spot on the bottom (where the screw was) to sand. The main use for it is the tight flat spots in the corners on the trigger bar.

Quote from Schmeky from the link below. ?-?It's really simple, here it is.  It works well on the rear of the trigger bar that contacts the sear trigger pad and the FPB lifter pad.  The top pic is how it looks ready to use, the bottom is how it looks when purchased new.?

After messing with several P guns I will say that the first step in tuning a P07/09 is to BUY IN PERSON!  Trust me on this.  It is MUCH cheaper to spend $100 more on a gun you can test the DA in, than one that MIGHT be a dud from the factory and cannot be fixed. 

Yes, many have purchased reportedly decent P07s sight unseen, and reportedly done well.  It CAN happen.  But it might not and some P guns cannot ever achieve a smooth stack/bind free trigger.  I own one.  Its bee cajunized, polished/tuned and even sent back to CZ and its just not right. 

I have another that was bad, sent to CZ, hammer and disco was replaced and is now a gem.

My best is an UG P09 that is a dream OTB. 

So, my advise on tuning a P gun is to BUY IN PERSON.

I would not recommend using a dremel.  Everything I smoothed in my P07 & P01 I did by hand with 1000 & 1500 grit wet/dry automotive grade sand paper. And the results speakfor themselves.

Power tools can take off too much material, and before you know it, you have an inoperable - or worse, unsafe - gun.

Just my 2 cents.

I've got to agree with briang2ad.
      I almost told my FFL to send my P07 back. The trigger was pretty bad, BUT, it fit my hand like a glove ! After 500 rounds, decided to tear it down and try out the suggestions from the folks here. "Night & Day" difference without any parts purchased ! Wife's a relatively new shooter & noticed the improvement immediately. She bought her own in ODG a year later that was superb on arrival.
     After another 2000 rounds I disassembled again, found a few rough spot, and did a little touch-up work. While both pistols prove excellent for defense, The Wife's still feels like a competitive pistol next to mine.
     Try before you buy still appears to be the most prudent way to buy a pistol !

My P-09 is a night stand pistol other than changing the sights to nights sights (Night Fision) it remains stock  . I figure just keep shooting it will get smoother over time . It is in the safety mode came that way .

This should be added to the main sticky.  I wish I knew this

I bought the MCarbo Spring Kit and followed their video instructions for tuning and polishing the action parts on my new P09. Overall, I'm very impressed with the results. The CGW recommendations on this forum takes the polishing a bit farther than MCarbo; may eventually polish the additional parts if I opt to break it down again.

Regarding the CGW Roller Bearings, has anyone replaced their? If yes, was their a marked improvement?

Roller bearings - it is all dependent on the size you already have in the gun. If you have a set of calipers and can measure, give CGW a call and they will tell you what size roller bearing might work best. The roller bearing does make a difference.

The CGW parts kits are way more comprehensive than the MCarbo stuff but you are also paying the price for them.

Personally a lightened spring kit is too superficial of a mod for me.

I think of other guns without the professional support that CZ has and their idea of a "trigger job" is to cut coils off a spring. What a rudimentary method.

It sounds like you are looking to push the envelope a bit with this gun. Call CGW and tell them what you are looking for. They will let you know what parts you need to get there.

Always keep in mind when polishing , never try to remove machine marks just polish.
I did polish too much one time and had to get some replacement parts.
And always stay away from the hammer Hook &  sear , that should only be done by an experienced professional gunsmith.

Should I just sand the pins and plunger block with sandpaper or polish with mothers as well? He mentioned just using 2000 grit to polish so im not sure.

[sickpuppy1]

Does this apply to the P10F also, as far as the trigger bar finishing and such? Not sure of the differences in internals?
Mine is gritty the first part of take up, and a bit upon release to reset. Not horrible but quite noticeable. Has about 3-350 rounds thru it.
