Any updates of how it has worked out? I installed mine and have been working out the little issues. I did notice the spring supplied just didn't seem to give enough tension(upward push). I wanted the catch to sit up against the rail and it just wasn't getting there. Anyway, I changed the spring with one from a AK parts baggie and it works now. Getting another hammer spring as I need the space and the stock hammer spring slides over the trigger frame and prevents the hammer from coming down low enough. I tweaked that spring but don't want it creeping back over. I am in the process of cerakoting
