How easy do you find it to hit the laser in a draw situation???
Not very. My thumb wants to press down on the elevation adjustment screw on the laser housing. They really didn't make it easy to find. That makes the laser useless in moments of extreme stress, which ironically is the situation where it would be most needed. If you have the extra second to activate the laser you can use the sights. IMO, that's the largest failing of this revolver- in trying to hit a price point they ended up trading away the one thing that would have made the laser useful- the "turn on as you grip it" feature you get with the Crimson Trace grips.
As for the speedloaders, IIRC it uses the same ones as the J frames.
