CZ MTR trigger adjustment

[Topwater]

Has anyone been able to adjust the factory trigger below 2 lbs.? If I have read their owners manuel and done the math correctly, it should go down to 1.8 lbs.

You can use the set trigger for an extremely light pull weight.
Don't tell CZ but I have a 527 with a 1.25Ib. trigger NOT using the set trigger. It is only safe as a target rifle but I by-passed the set trigger mechanism and adjusted the sear, replaced the conventional trigger spring to a lighter version. With a custom barrel I have cleaned 600 yd. targets with it more than once.

What caliber is your custom barrel chambered to?

I couldn't get my MTRs trigger below 2.5# before installing a Yo Dave spring.

A friend installed it for me and he also did some polishing and got it down to 6oz.

The 6oz. I could probably live with. I’ve gotten mine down to 2lb. 1.2 oz. I was hoping for something closer to my other bench guns. Going back and forth between 2oz. , 5.2 oz. and 2 lbs. isn’t conducive to consistent performance on my part.

Mines 10 oz. No YoDave spring or polishing. Just the factory adjustment screw.

I got mine down to 1lb by backing off the sear engagement until the cocked striker fell on an empty chamber before touching either of the other two adjustments. It's stayed right there since I bought it mid-March of this year. I shot it quite a bit with the OEM bbl before deciding I wanted to chamber & fit a Shilen .850" dia. straight select match ratchet rifled bbl, and have put several hundred rounds though that bbl. Best guess, I've probably got 1500-1700rds through it now, and the trigger hasn't changed at bit, near as I can tell. I doubt I'd be able to get it much under 1lb without doing something like the Yo Dave spring installation...based mostly on what I've heard from other 457 owners, and my experience with my 457 American, which I also re-barreled with a lighter profile Shilen.

I was in a similar situation. Minimum adjustment and mine wouldn't go below 2 1/4lb. I also did the YoDave and settled at 1.5lb (plenty good for my needs). Some people hit the trigger lottery with their factory triggers, it seems.

From my personal experience with both the 455 and 457, from the countless reports on the 455, and the half dozen first hand reports I've gotten on the 457, it was a step backward from the 455, pretty much across the board.
