They are popular being nice to carry but the triggers are generally heavy and that makes shooting well a little tougher. Personally I find the trigger and muzzle light feel hard to shoot well offhand and where I hunt offhand is 90% of your shots for hunting. They are smooth and fast to operate though as long as you never have to take it apart.
They can be a real headache to get back together with the rack engaged on the proper teeth of the pinion gear.
