When I did the 15 minute trigger job, my trigger pin never would stay in there good. Has anyone else had this problem? It's like the hammer spring wasn't putting enough pressure on it to hold it in there. I ended up just putting a new hammer spring in there because sometimes my hammer wouldn't strike hard enough to ignite the round. And has anyone cut the tail off of the hammer on their 15-22 to make it lighter?

I thought about taking the spur off the hammer but didn't go there. I also looked at speed hammers and wondered if one would work or even help the lighter strike. I did notice that it wasn't whacking the snot out of the rounds as much but, I've not had any trouble with it not firing. I wonder if the heavy hammer is leading to some of the exploded cases we've been seeing.

When you had the single leg hammer spring was the trigger pin's groove under the correct leg?

Yeah I've made sure I had the leg that is still there in the groove, but it still wants to creep out sometimes.
