One could wonder why if you had the ability to cock the hammer and possibly make a better shot, one would not.
Of course when I hunt glock I really have no choice.
Thats a nice shot though!
I'm starting to get to old to rely on irons at 50 yards any more with a handgun. Wish it wasn't so, but it is. It was some years back that 75-100 with irons went out the door too... a shame it tis.
