trigger
Excelent post from Rutty, it really answers most of the questions.
I'd only add, trigger set up on all the top makes as they are supplied from the factory is a base safe setting done on the production line, I hear so many people slag off a make when all it needs is a finite adjustment. Trigger adjustment is also close to an art form, it requires a very fine feel and understanding of what needs adjusting, some are good at it, others are crap, do not judge any trigger until it has been set up by some one who is good at it.
Weight, it has to consistantly lift a 500 gm weight, when hot, cold, from the box and after its been used, any top level shot will not have their trigger set to the line of 500/501 gm, a good tip is to put a £ coin on the weight when you set up.
Electronic triggers have a distinct advantage in feel, they feel different. When a mechanical trigger is at the point of break it has weight against the sears holding them on that point, when it breaks that weight is released,and the triggers felt weight is reduced, its like leaning against an open door, thats why we use a trigger backstop. With a free trigger such as on a free pistol or a match rifle that is not felt so back stops are not used. A 500 gm electronic trigger is the same, the release of the sear weight is not felt, the break is a micro switch and the weight before and after the break is the same, this is why an electronic trigger is advantagious as it can reduce the movement of the pistol at trigger break.
Personal preference yes, but there is also a distinct advantage.
Good shooting
