Best response so far.When I got my first Glock years ago, I was uncomfortable carrying it chambered because it was the first semi-auto without a safety that I had ever owned. I would cock it then insert a full mag and carry it cocked but unchambered. Every few days I would remove the mag and KNOWING it was unchambered I would point it in a safe direction and pull the trigger. Each time it clicked letting me know that it was still cocked and that the trigger had not accidently or negligently been pulled. This went on for 2 or 3 months as I began to feel more confident that the gun would not just go off if I was careful in handling it properly and especially with extra precaution when holstering. The day came when I felt ready to start carrying chambered and I loaded a round and never looked back. I can understand where someone is coming from when they are uncomfortable with a chambered round because I was there for a couple of months myself. I have never felt the least bit uncomfortable with a cocked and locked 1911.
I got my first GLOCK in my late 30s or maybe 40+, I don't really remember. By then I was a well seasoned CCr so there was no issue as far as carrying it condition 1.
I guess I never gave it a thought.
