Thanks, Bob. Is replacing the hammer something I can do myself (I'm fairly handy with tools and I replaced the trigger group in my 10/22, if that counts

)?
Also, what is the advantage of the competition rear sight? I figured I would just black out the white dots on the adjustable rear sight that is on it now.
BTW, I asked the guys at the CZ Custom Shop/Ghost Products and they said order the 5.5mm FO sight in either 1.0 or 1.5mm width. Since my rear sight opening is about .2", would the 1.0mm or 1.5mm be better? I assume bigger would acquire faster, but smaller might give better accuracy (since it wouldn't fill the rear sight opening so fully)?
I should mention that my goal for shooting IPSC/USPSA is not to win. My goal is to improve my gun handling. So, I'm not going to go crazy and build or buy a race gun. I want to use a stock gun (which I already own

) with a few simple changes to improve the shooting. Anyway, that's the plan today, it could change tomorrow.

Thanks for any help,
Dave
