Edit to add: your American is beautiful!!

A lighter spring will make a difference. There are kits (e.g. YoDave) that are supposed to help reduce trigger creep but I've not used one personally. DIP also has an adjustable sear that some have reported positive experience with.

My first American (22lr) came with a wonderful trigger. The gentleman I got it from is a member here who I later learned is a well known and respected gunsmith. It breaks at a very crisp 12 ounces. I remember testing it when I picked it up and commented about how nice it felt. Mr. Davis just smiled and said he knew how to tweak them. I don't know what kind of magic he did to it. (I didn't know anything about him at the time other than he was a nice gentleman.)

My 17HM2 also came with a trigger that someone must have tweaked. It breaks crisply around a pound.

My 22WMR and 17HMR Americans seemed to have stock trigger springs in place when I got them. I replaced them with lighter springs from DIP. They might not be as crispy as the other two, but they are still pretty nice triggers without any other modifications.

I figured I needed to act quickly before you spied this one. You have single handedly cornered the market for high quality classic rimfires.

 

Great looking 452. The wood and metalwork looks excellent. Happy shooting

 

The triggers are easily modified, with patience and shims and lighter springs Nice rifle.

 

Nice 452! I was shooting my 452 in M2 yesterday and it definitely needs some attention as well.

 

Great looking gun, and congrats!
I’ve done the YoDaves trigger change on both my CZ 457’s with 1 coming down to 13oz and the other come in at 10oz.

 

She's a beauty! Just add a Timney trigger!

 

Nice 452 American! Mine's one of my favorite rifle. Plenty you can do with the trigger. I don't have time to look for it now but look in the stickies for The Poor Man's trigger job. I bought a DIP adjustable sear for mine. Haven't installed it yet but that's supposed to be a great way to go too

 

I can take care of that trigger for you , it may take a couple years to get it back to you while I put a billion rounds through her. 😜 Free of charge.
I don’t mind at all!

 

Very nice 452. Great Walnut and blue steel.

 

Great looking rifle. An Ace hardware #144 spring will clean up that trigger. If you are impressed with your 452 now, wait to get out to the range. When you go to clean it be sure to use a .20 cal cleaning rod. The bore on these rifles are notoriously tight. A .22lr rod may get stuck.

 

I own 2 452's. Easy answer. Yo Dave kit or Ace Hardware #144 spring. Easy to do.

 

I have several different springs including the Ace #144. They help but will only take you so far if you have excessive sear engagement

 

I wish my 457 Varmint stock looked that nice. They might as well of took some brown paint and just painted it.

 

You can really see the difference in the finish of the wood and the polish of the steel from the 452 to the 457. I don't think it's my imagination but the walnut on the 452 seems more dense. Undoubtedly just a better grade of walnut on the older model. I mounted a scope today and will see how it shoots in the next few days. Hopefully will shoot as good as it feels.
Probably will install a new Timney. Lot's of guys have mentioned a spring change but my trigger has a ton of creep that I don't think a spring change alone will cure.

 

Buy the spring kit fron DIP Diversified Innovative Products - Main Page, just the trigger springs , you dont need the firing pin spring, although it might be good to have a spare. Easy peasy watch the utube video

iI like a trigger shoe , also dip, it seems to make it feel lighter and have less pre travel , aka creep.

 

A beauty for sure, poor man's trigger job is all but free, DIP kit works, just depends on you. I've done dozens of poor man's trigger jobs and have no use for anything else.

 

Great looking rifle.

 

I have a 452 Style.
I recently installed another Yodave shim & spring kit. It's the second one I've done. Mine is adjusted to 2 Lbs. with no take up, so there is NO CREEP. Just a clean break. It goes bang when you move the trigger. Everyone that fired the gun was impressed.
"This kit removes the creep and lightens the trigger pull weight by the use of shims and new springs. Kit includes 4 shims and 4 new springs plus a variety of roll pins to replace the original front trigger pin. Trigger pull weight can be adjusted from approx. 1 to 3.5 pounds."

 

That is one nice CZ you have there. The 452 American will give you accurate and reliable service for years to come. Out of 5 452's 4 have Yo Dave Trigger Kits installed and one has the Rifle Basix Trigger installed. Creep is none existent in any of of them after the kits were installed. Let us know how that rifle shoots👍🏽

 

Imho, the timney trigger for the 452 is way too heavy for my taste. I want light and crisp. Not 2 lbs and crisp.
Plus , I want a bit of pre travel , just makes it feel lighter to me. Like a 2 stage does.

 

You've invested in a beautiful rifle from a well known rifle maker with a well deserved reputation. I suggest you invest in a trigger that will make you happy and confident when using the rifle. Take the rifle and trigger to a competent gunsmith in your area and get the job done right the first time. My 2¢ and good luck.

 

Both CZ AND Rifle Basic offer a nice adj. trigger that is not expensive!

 

I've picked up a used Timney from another member. A crisp 2 lbs. should work just fine. This isn't a benchrest rifle and I can always explore the other options in the future if need be.

 

Is yours a B or C prefix? I have a couple of them with "16" marked on the barrel. My "A" prefixes all have "07" marks. B's and C's just say 2E but no ZKM. No matter when they were made, the 452's are great rifles and "just have that look about them". As I remember my 2 Grand Finales are marked "17" on the barrel and serial numbered below 0175. I do not own any of the 457's. Looks like they put the receiver in hot water and shrunk it.

 

I believe the number on the barrel is the date the barrel was manufactured, not the rifle. Although I suspect the two are close together. I own a 452 American with a 2017 date. I have seen none more recent. I own 2 452's and one 457 Varmint. I prefer the 457, although both are great.

 

Beautiful 452 American. You are gonna love that rifle. I am one of the few folks that prefer a 2 to 3lb trigger.
When squirrel hunting it just suits me better.

 

I totally understand. When squirrel hunting that's all that's needed. I like to have my triggers in the 1.5 to 2.5lbs. I have a friend(Brad) that likes his triggers in the oz's. If you think about it going off, it goes bang....😂

 

Receiver is marked CZ452-2E AMERICAN. CZUSA KANSAS CITY,KS
Barrel is marked CAL.22
LR
So it must be a B or C model. Haven't even shot it yet. Probably tomorrow.

 

Guys I gotta be honest I had no idea this was something special. Thanks for all the kind words!!

 

You done good! Real good!
