One more DIY fix.. Setting your lockup.
I've noticed if you have the pivot out and scale off so you can get to the back spacer screws. If you loosen those screws, put the pivot screw back in w/o the scale back on, and depending on if you push up or down on one liner side on the pivot end (toward the butt/clip end) will affect your lockup (early/late). So if you want to set your lock to a certain place, or if yours came from the factory way off, this is a way to fix it.
Does that make sense? I've had mine from half way across to where it won't even engage (WAY TOO EARLY). So play around with it.
