I purchased my Shield with a safety a couple years ago, don't know if the no-safety was on the market yet. On my last 2 trips to the range I loaded my Shield, brought it up to fire and both times I pulled the trigger and nothing happened. Forgot to take the safety off. I figure if I can't remember it at the range there's no way I'll remember it in a stressful SD situation. For this reason I no longer use the safety. The Shield is the first handgun I've owned with a safety, just can't retrain myself to remember it so it now stays off.
