I have an early model .22 GSP, with a coil recoil spring.
This is a similar spring to the one fitted in a .32 GSP.

Are the 2 springs identical in their strengths?

The reason I ask is I would like to lighten up the one in my .22, so it can take a less punchy ammo.

I am not shooting International competitions - just at club and Open events, so a velocity test with the ammo is irrelevant. However, I only want to alter the spring, not the breech block.

Has anyone done this sort of alteration? If so, I would be glad to hear from you.

Thanks.

Alex,

I believe that Walther supplied at least 2 different strengths of recoil spring for the .22 GSP, and, if I remember correctly, one of them looked very much like the .32 spring. I would suggest contacting a Walther expert/dealer to see about the different options before modifying what you have. If RayMac is reading this, I'm sure he could give us accurate info.

Hi,

I believe there are 4 different rates of springs for the GSP. The easiest way is to measure the thickness of the wire. The lightest is about .034", the next one up is about .037, the next one up I think is .040 and I do not know the diameter of the last one.

From what Earl told me, the .034 is for subsonic, the .037 is for standard target and the .040 is for the hot target rounds like greentag and such. The largest I believe is used with the rifle conversion kit. I used the .034 with SK subsonic and Aguila SE Subsonic and they worked great.

Another thing to consider when going to light ammo is if you have a plastic bolt handle. The GSP series mainly came with a steel cocking piece and a switch to the much lighter plastic will gain bolt speed needed with light ammo.

If you need a .034 spring and plastic bolt handle, let me know, I can help you.

Alex,
If you want to shoot lower velocity ammo replace the metal cocking piece of the GSP with the plastic one designed for the OSP.

PS: The reverse also works if you want to shoot standard velocity 22 Short in the OSP.
