I loved my DA/SA and practiced with it often. BUT once, without a moments warning, I needed it in a split second. I won the draw, but my second shot was WILD in that instant of adrenaline rush. I was settled for the 3rd. shot, but since the first was good, it was a moot point.
Practice, which you 'plan' for and expect, etc. etc. bears little relationship to reality when no warning, or expectation is present. Years of boredom, followed by seconds of fear can do that to you!
Anyway, I ended up switching to DA/Striker only.
