Had a major heart test last night! Woke from a sound sleep thinking I heard someone coming in my front door! My bed making all kinds of noise as I get to a 1911 I keep handy and racking the slide is noisy and I barely have the strength to do it. Damn night sights are getting really dim. Search around and it is a false alarm,but I still was awake a couple of hours before I could go back to sleep. Must have been dreaming but I sure thought it was real! Going to get some new night sights as soon as I can.
