MR. WICK, the photo that you posted a while back was of a 527 that would have the standard CZ Single Set Trigger (SST). You should only need to spend some time properly and carefully adjusting it, and it should be good.
As others have said, the Varmint MTR, which came out late in the 527's production run, did NOT have the classic CZ SST. Instead, the MTR had a single adjustable trigger, apparently like the one on the 557. As someone mentioned, the trigger blade is more curved on the new style non-SST trigger. It resembles the blade on the 527 and 550 SST up until about 2006 or so. The 453 used this same blade shape as well. After about 2006 or so they switched the 527s and 550s trigger shape to the less curved trigger that you see on the majority of those guns. From what I've read (I haven't owned an MTR or a 557), those triggers aren't designed to be adjusted as light as the classic SST can.
I have 8 CZs with the SST of the 453/527/550 style. I USED to keep the non-set mode adjusted as light as it would safely go, and kept the Set feature disabled. A few years ago, I spent some time on my 527 Varmint to get the Set mode adjusted down to a few ounces, and realized THAT is how I want all of mine adjusted because it tightened up my groups by a quarter inch or so. I have all of mine adjusted VERY light in set mode and IMO, the trigger is excellent. I used to not like the overtravel in Set mode (which is why I used the non-set mode), but some .2" - .3" 100 yard groups quickly make me not notice the overtravel. IME, a LIGHT, highly predictable trigger is an essential component for shooting one's best groups or maximum accuracy.
NOTE: If you want the Set mode REALLY light, you should be prepared for a little bit of trial-and-error before you get it just perfect after everything's all tightened back down. Get it right, and it's as if (for me anyway) you can just "think" that you want the gun to fire at a precise instant, and it does.
