Looks like everyone does work on their CZ's. My shadow will most definitely be a competition gun so I'll just toss out that if anyone has any old/extra spring kits or internals, guide rods, etc. that I can use to test out different spring weights or other stuff please shoot me a PM.
I'll be getting a hold of the wizard and asking in the forum about modifications at some point but before that I always learn my guns top to bottom and do a little tinkering and I would much rather keep all my stock parts untouched so that I can always be confident that if I put my stock internals in I'll be good to go. .
