Buy the Timney with the safety already installed. As good or better than the Shilen Trigger
I have Timneys on a couple of mausers and like them, but did a lot of reading before I decided on the Shilen. Timneys weren't getting as much praise as Shilen and Jewell, so I decided to try the Shilen.
I also wondered if a Jewell would be worth the extra money or not. Any opinions are welcome...
