I work on both CZ's and 1911's. 1911's are easier and have less springs. CZ's are not hard, there is a great video on YouTube that shows the break down of the CZ 75 and that covers most variants. The tricky part is the sear assembly and the trigger return spring. They also have a weird manual safety detent system. So, just be careful to manage your parts and remember your disassembly sequence because it's about twice the parts as a 1911. I own the exact shadow you bought. I put the reduced power trigger return spring, short reset disconnecter, 13 lbs main spring, and reduced power firing pin spring and it shoots even better than stock. Although, I admit I could have left the Shadow 2 stock and been fine. It is about as superb a factory mass produced fire arm as I have found in terms of the functionality it has right out of the box. As to CGW, they are super great guys and when you call they answer and take your questions. If you like 1911's do yourself a favor and buy a stock 97b off gunbroker, send it to David Milam at Cajun and he will do a full action and accu bushing job for 620. It is steep but I honestly cannot decide Which I like better, the CZ 97 or my 1911. My 97b is super accurate too. I paid an extra 160 and he machined a dovetail cut and installed a fully adjustable rear sight. I opted for the flat face trigger and it breaks like glass at 2.5 lbs.
