I have a walther osp. It came with an extra bolt and a gsp barrel. Sometime the second shot doesn't set the trigger. Does anyone else use an osp frame and bolt housing with a gsp barrel to shoot 22 lr?

OSP bolt is way too light for .22lr. It will be slamming back far too fast.
You need to add weight Like the GSP .32 bolt) to slow it down or you are heading for a breakage!

The receiver was the same for GSP and OSP, except for the sight position and the slant on the rear of the OSP. Any GSP bolt should fit and function. As noted, the original OSP bolt is too light and should be weighted to achieve functionality.

The GSP bolt will not fit/function in an OSP bolt housing.
For converting an OSP to ISSF-legal .22LR, please do a search on this site for OSP conversion and similar wording. The issue has been covered a number of times, best by Sandy Santibanez (another possible search phrase).

I have a converted OSP (from .22 short to .22 lr). The recoil spring is stronger, the bold is weighted down. It works flawlessly.
Good luck.
