Allowed/Recommend Modifications to CZ Shadow for IPSC Production

[Socrates]

Howdy,

I remember reading a thread about this, but my Google-FU is weak and I can't seem to find it.

I am most interested to hear if I will be able to replace the standard hammer with something a tad bigger.

You can change it out for the competition hammer. Not sure what you mean by "bigger".

The rules for Production are actually quite simple. These section deal with mods, with the first line being key.

Original parts and components offered by the OFM as standard equipment, or as an option, for a specific model
handgun on the IPSC approved handgun list are permitted, subject to the following:
16.1 Modifications to them, other than minor detailing (the removal of burrs and/or adjustments unavoidably
required in order to fit replacement OFM parts or components), are prohibited. Other prohibited
modifications include those which facilitate faster reloading (e.g. flared, enlarged and/or add-on
magwells, etc.), changing the original color and/or finish of a handgun, and/or adding stripes, stippling or
other embellishments.
16.2 Magazines accessible to a competitor during a COF must not contain more than 15 rounds at the Start
Signal. Identifying marks or decals, internal capacity limiters, bumper pads and additional witness holes,
which add or remove negligible weight to/from magazines, are permitted.
16.3 Sights may be trimmed, adjusted and/or have colors applied. Sights may also be fitted with fiber optic or
similar inserts.
17. Aftermarket parts, components and accessories are prohibited, except as follows:
17.1 Aftermarket magazines are permitted, subject to 16.2 above.
17.2 Aftermarket open sights (see Rule 5.1.3.1) are permitted, provided their installation and/or adjustment
requires no alteration to the handgun.
17.3 Aftermarket grip panels which match the profile and contours of the OFM standard or optional grip
panels for the approved handgun and/or the application of tape on grips (see Appendix E3a) are
permitted. However, rubber sleeves are prohibited.

If it is a CZ OEM part, you are GTG.

I know a few guys run the extended firing pin.

They do make one.

Okay cool, that's interesting. My basic rules of thumb was that if I can't find the part on http://www.shop-cz.com/ (official CZ store) then it's not legal. I've never seen the extended firing pin on the official website. There's lots of items for example that are sold by czcustom.com that are exactly that, 'custom' and are not legal for Production.

I also know of several guys that use the longer pin, as long as it's officially a CZ replacement part that's fine, if not, it's not fine.

TREAD WITH CAUTION:

Guys, if you are running an extended firing pin in a Shadow, trust me, there is no reason to use a reduced firing pin spring.

You do so at your own risk, she can and may run full auto, trust me on this one
