The wrong recoil spring can produce double feeds, stove pipes, and angle jams where the slide has “crashed” into the case, pinching the cartridge. However, bullet weight can definitely affect operating pressure, if the same powder charge is used. A 115 grain bullet can produce a much higher operating pressure than a 124 or 147 grain bullet, with the powder charge being the determining factor. You select the recoil spring based on the operating pressure of the load. You DO NOT select the recoil spring based on bullet weight. With the correct recoil spring installed, the main issue will be reduced to the magazines or the ammo. Item #4: if your CZ has the correct recoil spring to match the pressure of your load, then mis-feeds, jams, and improper feeding are virtually eliminated. To get this distance into the preferred 6 – 8 foot range, you would need to use either a 13# recoil spring (ejection distance would be 8.5 – 9.0 feet) or a 14# recoil spring (ejection distance would be 6.5 – 7.0 feet). EXAMPLE: your out of the box SP-01 with a 16# recoil spring produces an ejection distance of 2.5 – 3.0 feet. 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.

then yes the one I originally linked would be stronger.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. Maybe i ought to look there instead.Įdit: but I guess to answer my original question, if the flat green spring is 14 lbs. Not exactly inspiring any confidence there but anyone I had asked about it said its probably fine. I bought the gun when I was in California so 10 round capacity, and when I had up to 9 rounds in the gun everything seemed fine, but once i put the 10th round in the magazine had this really weird rattle to it. I've wondered about them from the very beginning.

It seems to happen at different times.ĭuring rapid-fire situations, when I first drop the slide on a full mag, middle of a mag.

Someone else asked when the FTF was happening. I've been shooting for a long time so I know I'm not limp-wristing the gun, I'm just wondering what it would be. It just felt awfully flimsy and didn't since it didnt look like the recoil springs I'm used to seeing I was assuming it was a different material. Thats exactly the recoil spring I was referring to:
