morini- how to set second pull travel and weight

[ar15t0tle]

hi, I'm a novice at the sport(air pistol -olympic, 10m ). I'm currently shooting 345/400 to 360/400( i don't know how good that is!) my second pull on morini electronic trigger is very crisp, I would like to increase the travel of the second pull without disturbing the trigger weight, thanks in advance for your valuable comments and help

Shouldn't have bought the electronic Morini, then. No good way to get a roll over trigger, or even something in that direction. It's possible to vary the letoff point with the vertical screw (1.2mm, it's probably not mentioned in the manual) on top of the trigger module, but I don't think that this will get you the desired result...

thanks tycho, for the reply. Any other method to tackle the problem. Also generally what are the problems with a crisp trigger; how does it affect shooting parameters, pl guide.

Well, you could try to use a 500gr spring on the first stage and remove the second spring completely - that should give you a full rollover trigger, but with 100% weight on one stage, which I'm not sure is what you are looking for in AP. On the other hand, 95% of all shooters seem to use and like the conventional two stage trigger for AP, which is widely documented in literature and internet. Just don't go too low on the second stage weight (start at 50/50 or so) and keep building up pressure continously while concentrating on the sight picture, whatever activities your front sight may be up to :-)

thanks tycho;
any literature available on the net or elsewhere on the same?

If you remove the second stage spring from a Morini the trigger will not work.
The second stage spring holds the trigger bar against the switch assy.

A small rolloff can be found on early models (15v battery) via the vertical screw, but later models have a different switch assy and have a crisp let off.

You need some weight on second stage to feel the trigger (80-120g of the 500g ).

If second stage is too light you will tend to grab at the trigger when the sights are right (point shooting and playing Gotcha !!) the result is a trigger snatched shot.

With a little weight you must squeeze the trigger while you are in the aiming area allowing the trigger to break.
