What are these O-rings about?

I keep seeing people post about O-rings in their SR22's. Being a new SR22 owner, I would like to know what they are for and where they go?

They simply act as a rubber buffer between the muzzle cup and slide stop lever. When the pistol is fired the slide moves rearward due to blow back gasses. The recoil spring is compressed, the hammer cocked and the lower portion of the muzzle hits the polymer take down lever which acts to stop the rearward movement of the slide. Since Walther P22 were cracking slide....O rings were added over the guide rod and recoil spring to act as a buffer. Since the early SR22s were breaking the take down lever I suggested that the same O rings could act as a buffer to soften the stop of the slide. Both pistols are very similar here and the same O ring fits both. I've had on in a P22 for over 5,000 rounds. There was a long thread on this with plenty of pictures but I can no longer find it.

That is an interesting recoil spring. Is that the Walther .22 ?

I can't believe that they actually still sell P22s, with the reputation that they have and the availability of the SR22.

What's funny is I often see P22s listed at higher retail prices new than SR22s on the same site.

I photoshopped this picture for some reason. Can't remember what we were discussing. This was back when the issue of the lever breaking first reared it's ugly head. Yes, the recoil spring earlier is a P22 spring. The Ruger set up is very similar to the P22. Walther uses a solid polymer lever that is fully supported on the rear by the frame. Ruger developed a hollow one with a spring and plunger. So they broke. Walther made a thin cast zinc slide....so they broke. A little testing should have found both issues before being released to us. M1911
