posible saftey issues 29/12/2014
I installed this sear & spring in a new 77/22 wrm. It required filing the safety pad on the trigger to be able to engage the safety. Testing the trigger it broke at 2- to 2 1/4 lbs, and was crisp. The problem I encountered when closing the bolt the sear would not hold the firing pin from going forward and it would uncock the gun. If I closed the bolt very slowly, not in a normal manner it would stay cocked. This looked like a very dangerous condition. The instructions said if this happens, there is not enough tension on the sear. I took out the Timney spring and put the old factory back in . That solved the problem, but raised the trigger to 3 1/2 lbs. The photo shown would make you believe the sear is adjustable, it is not. The next time I would just buy a whole trigger assembly. I will try a Wolf aftermarket sear spring, to improve trigger pull. If this would have worked properly I would have given it 5 stars.
Be careful fitting it 04/06/2011
To fit this you must file the safety pad on the factory trigger. If you go too far, you can not buy a replacement trigger from Ruger, you must either send the rifle back to the factory or put in an aftermarket trigger. I put this sear in a M77/17, but it had a lot of creep. I then tried it in a M77/22, and it gave a nice 2.5 lb pull. I eventually put a Rifle Basix trigger in the M77/17 and it was MUCH easier to install and gave a better pull. I would not buy the Timney sear again and would not recommend it.
