Yesterday morning I called Yar to order some parts and get some recommendations from him for my two glocks. I get to my office this afternoon to find a wonderful little package waiting for me! Can it be!?!?! I felt like a kid at Christmas! An hour later I had everything installed in both the 17 and the 23. All I can say is WOW! Dry firing it I can tell a huge difference. Now I have to bring the wife to the range this week to give it a test since waiting for the weekend is not an option Again Thank You VERY much! You rock!
