Hi There.

Just wondering if anyone here had the 11 lbs recoil spring installed in their CZ shadow.

If you do, what were the results, better worse recoil ? any feed issues ?

have a new CZ enroute, but was wondering if it was worth the few bucks to change springs, or if there are any other suggested mods that I should do to it.

Yeah, I know, it is a great gun as is, shot it a few times when out with buddy, and also at local range, but would like to " sweeten it up a bit "
 
I have the 11 lbs recoil spring installed on mine.

To me, it helps the gun shoots flatter, i.e. the sight will come back almost effortlessly to facilitate the next shot. With the original factory recoil spring, I found my sight "dived" a bit more to my liking, as such I had to bring the sight back up for the next shot. The end result for me is a better split time and a more controllable double taps. I really couldn't feel any difference in terms of recoil intensity. No issues with feeding/ejecting either.

YMMV, it also depends on your grip and your ammo (I shoot mine with 130 PF reloads).

Hope this helps!
 
My thanks for the reply

the ones I shot were on the 13lbs springs, and grouping at 50 ft were excellent, but my target acquisition was a bit slow between shot too, as muzzle jump on this one was up and right. never started reading on recoil springs till after I ordered one

I loved the recoil on this, but in my newbie mind, lighter recoil spring would increase recoil and barrel rise. I am an experienced shooter, but never got into the modification aspect of pistols.


do you have the trigger spring modified on yours ?
 
You need to match the recoil spring to the ammo you're shooting. The 11lb is working for rising_sun because he's shooting lighter loads with his 130 Power Factor ammo.

If you swap springs and shoot the stronger regular factory ammo the spring will not soak up all the recoil impulse before the slide crashes into the frame. This will lead to damage such as more frequently broken slide stops and possibly end up with cracks in the slide or frame.

The ONLY reason that other rate recoil springs are sold at all is because some of us shoot lighter or stronger ammo.

To lessen the recoil felt through the frame you actually want to use as STRONG a recoil spring as possible that still allows for reliable case ejection and reliable lock open after the last round. A setup like that will kick back through your hands only through the spring instead of having any shock from the slide being stopped by the frame instead of the spring. If you use too weak a spring the empty case ejection will be very strong but you'll likely notice more sharp shock pulses in your hands due to the overly strong metal to metal contact of the slide battering the frame at the rear travel limit of the slide.
 
Replaced factory 15 pound recoil spring with the 13 pound recoil spring. Gun shoots better, flatter tighter groups. Have read the 11 pound recoil spring is only recommended for light loads, or competition. Ordered Steel guild rod too replacing factory plastic one, prefer metal over plastic. dlaskarms.com is the place to go, also got the recoil buffer with steel rod, couldn't put slide back on gun with it, working on it later the week.

Food for thought. CX-75 shoots out of box like a laser. You'll be envy of all non-CZ75 owners.
 
so using factory ammo of various loads, I should stick with 13lbs. ?

not going to get into reloading anytime soon, as wifey would have me mounted on the wall if I started LOL
 
ya lost me at tagged. whats tagged ?

my thanks to you all for your help

ya sold me, gonna order the 13 and 11 lbs springs, and play around with different loads, was sure the pistol came with 13 lbs, but after some more reading , Vegas Mike was right and it comes with 15.

This is solid gold advise.

I shoot light loads (130PF) and run a 11 pound spring. I also popped in a 13 pound hammer spring and a longer firing pin. Trigger pull in DA went from 12 pounds to 8, SA was lighter as well. I never saw the need for a steel recoil spring guide rod but YMMV. The gun runs flawlessly but if I were to increase the PF I would also increase the recoil spring weight.
I used Select Shooting Supplies, Dean had everything and was great to deal with.
 
For IPSC if you reload, go with 11 lbs recoil and 13 for hammer. Dry fire at least 500 to seat internals in.
 
13lbs for the recoil spring would be worth trying. But watch for signs through the frame that the slide is battering the frame at the impact point. I did find that the 15 seemed a touch strong.

For sure I would not even consider using the 11lb recoil spring with any sort of factory ammo. Save that for later when you can find or reload some minimal power factor loads.

The 13lb mainspring for the hammer is a slam dunk winner. And if/when you reload if you're using Federal primers and tune up the action you can likely get away with an 11lb mainspring. And at that point your DA first shot trigger pull needed for Production or SSP will drop to an ounce or two over the 5lb minimum.
 
Thanks BCRider

going to get both 13 and 11 lbs springs, not sure if I'll ever get into reloading my own, but at least will have the 11 on hand if I do ( if I do = if wifey lets me....yes I am that whipped ):HR:
 
At least you know when you're beaten and where your place is.... :d

It used to be that we could sell the idea of reloading as saving money over the long haul. But of course "we" all know that's horse patties since we just end up loading more for the same money outlay and shooting more and saving nothing at all.....G:
 
the quickest thing you could do to make a world of a difference to your Shadow is change the recoil spring, main spring, install a shorter disconnect, competition hammer, and then polish the sear and internals (anywhere you see friction marks).

All of the above can be had for under $150 and will hot-rod your Shadow more than it already is. I shot my stock shadow for a year before the aforementioned upgrades and its a huge benefit.

Do it, you wont regret it.
+1 to matching springs to ammo.

Remember: springs are cheap, frames are expensive.

Also, pick up a spare slide stop. I havent broken one yet but I have friends who have, and its a 2min $40 fix vs a complete waste of a range day/match fees.
I went with a flush slide stop because I have giant hands and would always hold the slide stop down accidentally. The flush slide stop solved that problem.

Good luck, and you will love the shadow. You wont regret that purchase!!
 
Thanks Trazor,

Those mods sound great, and I will get them done as soon as it comes in....truth be told, I had to look at cz breakdown schematic to figure out what some of the parts you had listed were

as I said, I shot tons before, but never modified anything, just shoot, clean, and put away.

Funny story on the shipping of this, turns out that CP decided to return to sender without any reason.......item was shipped and received in Edmonton in record time, then for some reason unknown to myself, shipper or Canada post, was taken off the truck in Edmonton, and put on the eastbound truck back to Ontario...no delivery attempt to my house, no contact what so ever....still not sure where its at yet, but seller is hunting it down.
 
"the quickest thing you could do to make a world of a difference to your Shadow is change the recoil spring, main spring, install a shorter disconnect, competition hammer, and then polish the sear and internals (anywhere you see friction marks)."

Honestly never felt the need to mess.....I get the spring thing depending what load you're shooting, but mine was just awesome from the get go....should I dive in and make the changes? I really don't need a lighter trigger, I've done the ocasional double tap with the trigger I've got....tis a short reset...but I'm genuinely interested?????
