On the real L85 the trigger is 2-stage. It requires a fair amount of pressure to fire a round. As for the airsoft version- what do you expect? All airsoft guns have weak trigger pulls offering no resistance, as they are basically a switch lever. The safety catch is more secure than the swivelling type as long as you remember not to fiddle with it.
As for that, as you train with one and get used to mag changes it gets easier.
It's easier to take the bolt carrier out of the M4 as the rifle 'breaks open' like a double barrel shotgun when you remove the rear body pin, enabling you to pull the bolt carrier out with the cocking handle. The gas parts are a different matter entirely. It's much easier to take them out on an L85; you just pop the top cover open on the handguard, pull the gas piston to the back of the weapon and pull it out of the weapon on an angle away from the gas collar- the gas collar just slides off and the gas plug can be taken out by depressing a locking stud and pulling it backwards. Much simpler for what it is.
(Plus I'd rather not have to pull through the M4's gas tube to clean it)
