Yes, I did. It got rid of the long slack in the trigger. I like it.
You have to get used to making sure you release it enough to reset, but it improved my trigger quite well.
It's not hard to do, but if you install it yourself be very mindful of how the stock trigger comes apart if you think you might need to revert it back to stock. My trigger spring popped off and the trigger came apart and I'm afraid that I'll need to send it back to Ruger to switch it back if I need to...
Take close-up pictures if you can.
