  1. IMPORTANT NOTE: at 15:05 the hammer springs are situated upside down! This is how they came from the manufacturer (for some odd reason) and I did notice this and ‘flipped’ the spring prior to install. If you put them in the way the video depicts at 15:05 you will probably have light primer strike issues.
