Each pound change in the recoil spring will change the ejection distance 1.5 – 2.0 feet. The CZ P07 & P09 both use a 20# recoil spring. The compact 9mm metal framed CZ’s use a 16# recoil spring. The OEM recoil spring weight in a full-size 9mm CZ pistol is 17#’s, including the CZ-97 in.

Finding the optimal spring can be trial and error. Too light of a recoil spring can make the muzzle rise too much and puts added stress on the slide stop pin. Too heavy of a recoil spring can cause the muzzle to “dip”. Item #3: there are 2 criteria for determining the correct recoil spring poundage: an ejection distance of 6 – 8 feet, and for competition shooters, how quickly your muzzle gets back on target. Obviously, you can only determine the correct ejection outdoors, so if you only shoot indoors, you must find somewhere to do some testing.

A full slide stroke allows the spent case rim to contact the ejector with full force, producing a strong, long-distance ejection, a critical function for a reliably running pistol.

Recoil buffers can cause ejection problems by short cycling the slide, plus when the buffer breaks, as they all eventually do, it will drop broken shards into your CZ’s lock work, rendering your pistol inoperative. There is no such thing as “slide or frame battering” and the installation of recoil spring buffers can prevent the slide from achieving its full stroke. Item #2: the slide must travel its full stroke so the slide abuts the frame, just as it was designed to do. The majority of the time folks follow the bad advice given on YouTube videos and on the internet telling folks to use a 10 or 11# recoil spring, which is incorrect unless you are using very light loads. Pistols that eject a case 12 feet or more will prematurely break a slide stop, can produce excessive muzzle rise or lift, and can increase felt recoil. This is the ideal slide velocity for reliable extraction, ejection, and subsequent feeding. Item #1: the optimal slide velocity will eject a spent case, on average, 6 – 8 feet away from the shooters stance.
To understand the recoil springs’ function, we need to examine what it does and how it works.

Now I have to see if I can get it separately or buy the kit.The recoil spring is one of the most critical springs in a semi-auto pistol, yet most shooters install the wrong spring the vast majority of the time. It pulls the hammer farther back to give it more inertia in double action. Reduced length of pull yes for me.ġ3 pound hammer spring, yes but I should have picked up the Wilson kit with the Ultimate Trigger Bar. I replaced the recoil spring with a factory weight spring, after I got my parts in a friend sent an email recommending a heavier spring. The trigger bar is made to pull the hammer back just almost as far as the single action to eliminate light strikes. If I had seen the Wilson Trigger bar kit before I ordered springs I would have got it. It sits about an eighth of an inch further back. The reduced pull length trigger is nice for my short fingers. With old factory springs it was 5 and a half pounds average but went from 4 pounds 10 ounces to 6 and a half pounds randomly. The single action was an even 5 pounds over ten pulls and felt great. Probably 9 to 10 pounds from 12 pounds or so, I had 2 light strikes in 40 rounds, needs work. The hammer and trigger spring did not make the double action as light as I had hoped. Not noticably thicker in the hand but a much better grip surface. Let's start with the Ergo grips.īy a hair thicker they are 3 thousandths wider behind the trigger.
