laufer! i have owned a p-01 for 9 years and first thing as a newby to cz pistols i took it apart and polished it and put in basically a pro pkg without the reach reduction kit and an extended firing pin. yes the decocker can be a pita but with some patience and a few video tutorials you can do it. my second cz i just bought a month ago! this time a sp-01 safety model. simpler sear to do than a decocker because of less parts and does not nead a slave pin to put back together and insert back into the frame. after 9 yrs i took on the task of again opening up a brand new cz and polishing it and adding the complete pro pkg this time. i was rusty but with the bit i remembered and the help of the links on this forum and utube i made it in a weekend . my advice is to utube the pro package install, watch a few videos, look over a few threads , and then decide if you think you can do the work. materials you can use sand paper in a few grits, a dremel with buffing bits and polish, a few punches, a small hammer and a block of wood with a hole drilled in it . my p-01 is under 3 lbs single and under 8 lbs double. the sp-01 i just did that is unfired is 3 lbs 6 oz single ,and 7 lbs 8 oz. double. started out 5 lbs 6 oz and 10 lbs 11 oz. you can do it if you take your time,take lots of pics for reference. the p-01 i did almost entirely by reading and looking at Walt-Sherrilll's tutorial here, and the sp-01 was also a link i found here on the forums by Scarlett Pistol. his videos broke each section down and i just found the section i was working on and followed along by stopping and starting as needed. not the same pistol as yours but lots of info apply from one to the other model.
