I was ready to drink the Koolaid yesterday, based on comments on this board and others, and jump for a nice LH CZ452 Military style 22LR yesterday. Right up until I asked the gun store to remove the trigger guard so I could feel the trigger...which is about as bad as I've ever felt on a gun. Gritty, hard, you name it. What kind of trigger modifications are necessary to the stock trigger and how difficult are they for an amateur to do?

you can get a "Yo Dave" trigger kit. it's very popular on rimfire central. i put one in my 455 and it made it much better. affordable and effective.

there are other options that don't require the kit (poor man's trigger job). go check out the CZ forum on rimfire central.

They are adjustable from the factory, so you might want to start there. There are also some DIY trigger jobs (search RFC for detailed instructions), the results of which some people prefer over the aftermarket triggers. Perhaps it's a bit of a luck-of-the-draw thing, but my 452FS had an outstanding trigger out of the box -- significantly better than the factory setting for the highly-regarded single set trigger on my CZ527. Good luck, but you should be able to get it working very well with minimal effort.

Recently did the Yo-Dave Trigger mod on a new CZ 452 Ultra Lux.

Just Wow...what a great trigger now. Be aware that the Yo-Dave Kit contains enough springs and shims to do more than one rifle.

Check out the CZ/Brno section of rimfirecentral.com

I used the YoDave on mine for a much better trigger.Don't forget the bump safety test.I use a rubber mallet on the removed action to protect the stock from a crack or split.

No forward push on a 452. You're thinking 453.

Thanks to all, especially I6turbo for the link. I think I'll take the plunge.

Well, I did buy it on Thursday and today I separated the stock and the action and lightened the trigger.

There really isn't much movement available from the adjusting nut, and I'm too impatient to wait for a Lo-Dave kit, so I simply cut a couple of full turns off of the spring. For future reference, don't do that. Holy Bubba! Subsequently, the trigger wouldn't engage the sear upon cocking. I had to take it apart yet again and I simply "pulled" the spring out a little longer...and it finally worked! Pull is around 1.75-2 lbs at present and crisp.

And it resulted in a 25 yard, metal sights, 0.75 inch five shot group this morning. The 452 was a nice purchase and I have everyone here to thank for it.
