I played around with the trigger this weekend and WOW, those triggers can tune up nicely. I didn't get pics, the camera was dead and I was impatient. First thing I did was add the second lightest spring from the yodave kit. This made the trigger pull crazy light but the significant amount of creep was still there. Next I had to decide between the DIP adjustable sear or the yodave shims. I went with the sear first because I didn't want to drill the other pin out if I didn't have to. The adjustable sear was relatively easy to install as long as you use some grease to stick that nasty little ball bearing onto the spring. The kit did include an extra in case you lose it. I followed the instructions and adjusted the screw until it just touched, then gave another 1/8 inch. The creep was less but just slightly still noticeable. Another 1/8 turn in and the creep disappeared completely. Put the stock back on and wow, this is one of the nicest (and lightest) trigger I have ever pulled. I'm not sure how you could ever handle the lightest spring in the kit. Now for the rubber mallet test. It takes a bit of a blow, but the trigger will fire consistently when hit. Once this gun is strictly benchrest I will use the second lightest spring, but for now, with the 17 hmr setup I plan on killing a lot of gophers this spring and don't want an accident. The third lightest of the four springs still feals amazing compared to stock, and the rubber mallet could not set it off. I'll have to wait for my next CZ purchase to install the yodave shim and do a proper comparison. For now, and because of ease of adjustability, I would say the DIP sear is well worth the 40 bucks it cost. Just get the spring kit, or yodave springs to go with it.
