Sorry to hear about your incident and glad no one was hurt. If you are unsure about handling the Glock then you are doing the correct thing by putting it away, especially if you have alredy taken a safety course. I use the Safe T Blok in all my Glocks and the Blocks stay put until I am ready to fire even though I am well versed in keeping my trigger finger out of the guard until ready to fire. I hope you gain your confidence back in the future. Unless you are on some medication that interferes with your judgement, age 59 should not be causing your problem. I am 72 and CCW every day and practice once a month. For a short time the Dr had me on some strong Blood Pressure medicine that made me kind of 'fuzzy" but I had him change it and now all is well.
