Well, I got hold of a NIB '91 Pre-B a while back and am finally getting around to setting it up for USPSA in time for the Area 2 Championship.

Here is what I did.

Install .130" tall Dawon Precision front sight.

Design custom rear dovetail to eliminate existing rear dovetail and avoid cutting into slide serrations. Manufacture a custom rear sight from barstock to match dovetail.

Serrate rear of sight at 50lpi and cut square notch (.135" wide)

Bevel Magwell

Blast off baked coating and Hot Blue frame and slide (I polished the slide flats)

I will be getting a CZ Custom Comp hammer w/13lb mainspring and Miossi sear as well as thin aluminum gips and some Mec-Gar mags to finish it off. As soon as I have all the parts I will do some extensive action work and shorten the reset and I should be good to go.

Rln_21,

That work looks excellent but you have a measurement to make if you are planning on shooting in Production division: (Appendix D4)

22 Specifically prohibited
modifications and features
•Prototype and Single-Action-Only handguns.
•Disabling of any external safety or externally operated
safety.
•External modifications or features such as weights or
devices to control or reduce recoil (such as, but not
limited to, thumb rests or components which could be
used as such).
•Grips - Any addition or removal of material which
changes the factory profile or adds function such as
beavertail or thumb rest.
•External plugs (such as Seattle Slug).
•No magwell attachments or external flaring of the
magwell. The lateral width of the well may not be
more than 1/4” wider than the lateral width of the
magazine.

Hope this isn't a problem!

Later,
Chuck

Nope, this is a personal project. We refer all CZ work to the real CZ experts at Apex Tactical.

Shouldn't be a problem, I only created a .050" bevel per side on the magwell so a .100" (1/10") total increase in magwell width. Should keep me well under the .250" over mag width requirement.
