Have a lot I really want to add to this thread but I will keep it focused to the two choices the OP asked about.......
The SDP is a nice setup.....there isn't really a reason for the short reset trigger (SRT) for a daily carry gun.....I've modified about 35 CZ pistols over the years and will not install a SRT for a carry gun, reason being the trigger pull is too short & light for safety sake.
The Pro-Tek is a pretty extensively modified pistol for sure......but the money asked for all the bells & whistles don't add up anywhere near an equal value in performance. $2K is just crazy money, in fact I feel comfortable saying that a stock CZ (any model) could be made to function superbly for about $100-150 in parts....stuff a novice could do.
Just one persons learn-ed opinion......I even have issues with the money being asked for a SDP but its more "reasonable"
in the end.......Bottom line, whatever you do just enjoy it!
