I put a Timney Trigger on my VZ-24 Mauser (98) about two years ago. The difficulty I ran into was that the trigger sear had to be shortened as when I would take the gun off safe, the firing pin would fall. I started to do it myself but didn't feel very comfortable doing it because if you grind off too much, then you have to replace the firing pin assembly. I took it to a gunsmith to finish the job.
