Finally tuned my Prosport with delrin guides, short stroke and weihrauch seal. What a difference, hold sensitivity has disappeared, accuracy is fantastic and the firing cycle is beautifull and quiet. Didn't really rate it before compared to my tuned .177 97 but it has been transformed.

Was hesitant before cocking the first time after what I'd heard but no problem at all. Will chrono tomorrow.

A very happy bunny ☺
