Best bang-for-buck upgrades for pre-B
« on: September 07, 2012, 11:59:09 PM »
Hi All,
I bought a Pre-B CZ75 a few months ago. I have really enjoyed the gun, and I would like to spend some money to improve its performance. The sights are way small for my bifocal-qualified eyes. The gun also seems to shoot consistently low for me, no matter how much attention I pay to stance, grip, posture, sight alignment, etc., so I have ordered an adjustable sight from Fusion Firearms to allow me to dial things in a little better. That's done.

I believe the pistol is basically in as-manufactured condition. Some sanding/polishing has been done on the bottom of the sear block, but I see no signs of any other polishing work having been done. I looked at the hammer hooks with a magnifier and from the roughness of the surfaces, it does not appear to my (admittedly untrained) eye that they have been worked on. However, I have not removed the hammer from the frame, so I cannot see the surfaces that contact the sear edge well.

I am weighing several options:

1. Having the fixed front sight milled off and cutting a dovetail to permit fitting another sight that is easier for me to see.
2. Installation of CGW race hammer kit.
3. Installation of a lighter hammer spring and a new recoil spring.

I like the fiber optic front sight on my Buckmark, so I am leaning heavily in the direction of prioritising sight replacement. Would a 1911-type dovetail be the best choice?

The springs are cheap, so I think that's a no-brainer. I am most concerned about the work on the action. I am perfectly capable of disassembly/re-assembly and polishing non-critical areas on moving parts, but I hesitate to fiddle with the hammer/sear interface.  Is the CGW 'Race' hammer kit the way to go? It looks like it is cheaper than their Kit#3, which uses a modified CZ shadow hammer.

For now, this gun is used to perforate paper. I do not carry it, nor do I use it for home defense. It stays locked up tight in a gun case, stored on a high shelf in a closet. I have pre-teen kids at home and I do not take chances with them or their friends stumbling across a loaded gun. However, I will be using it as a house gun once my youngest reaches a sufficient level of maturity (whatever that is), and it could potentially serve as a gun for the car once my CCW permit goes thru. So, I do not want so light a DA trigger that the gun becomes unsuitable for self-defense. I do think reducing pre-travel and over-travel in the trigger would help my accuracy at the range.

Neglecting the rear sight, I would like to limit my budget to approx. $200.
Does anyone have any insights they would like to share? What have I not thought of? Fire away!

Just my .02 cents.

Do Option 1 and 3 at the same time....that's within your budget..... Shoot the pistol a couple of thousand rounds... Then do option 3....which I highly recommend. I have race hammer on two of my CZ. Also I have a CZ pre B 85 with a Novak rear and 1911 dovetail cut front which I'm replacing with fiber optic sights soon.Here is a photo of the slide for you to get an idea.

I don't trust those fiber optic sights, they seem like they would break easily.
