My first gun was a Glock 22 and it took me a while to get used to the idea of the "safe action" feature.
So, I put a Slider Lock safety in it.
Crossbar Safety for a Glock.
The first night I had the safety in the gun I put it in the bedside gunsafe and as I always did before I went to sleep I reached up and fumbled the buttons in the dark and reached in to pull the gun out. (building a habit so I would not have to think about it if the situation ever arose) As I lifted the gun I realized I was pulling on the trigger and not the trigger guard.
If I'd not had the Slider Lock in place I'd have shot a lamp, a wall and a toilet at 11:30 on a Sunday evening.
The argument for carrying a round in the tube is, in my opinion, quite valid, but it has to go with training and safety measures. Just like driving on icey roads.
I figure practicing safe handling of weapons gives me something to do
and a good reason to play with my guns.
:shock:
