I could come up with a hundred scenarios why you should have a safety and a hundred why you should not. Go to any IDPA or other tournament and see how many people forget to disengage their safety. It happens. Now ask yourself this. What if that was a real life situation. I am not sure if you have ever fired while under stress and their are different levels of stress. Shooting IDPA is stressful because a lot of people are watching you plus you would like to win so those two stress points make even the best practiced people forget to disengage that safety. It happens. In my opinion the best carry is one that you draw and fire. Everybody has their own opinion but if you can justify a safety then you can also justify not putting one in the chamber and just practice racking the slide every time you draw. People will say it is no problem for them but in a nut shell. It is one less thing to worry about. Period. No safety for me thank you.
