Cressi SL Trigger and mods

[Gazz]

Hi Guys, i finally got around to pulling my cressi sl apart. It was full of the white o-ring grease (chunks everywhere). I have only used it once and havent liked its stiff uncomfortable trigger. (I have a Mares and Airbalete which have great triggers, and have used a asso whick was ok).

It was possible the trigger spring had come out of its holding hole but the spring is still very very stiff. has anyone ever cut the trigger spring or tried using a softer spring? The spring in my opinion is the greater problem than the 3mm thick firing pin.

also i have been hearing about people polishing the inner barrel, how do you do this and where would you the the parts?

Thanks any help would be appreciated.

That coil spring gives the sear lever the snap action to hook firmly onto the piston tail, so I don't think you should weaken it as you don't want the sear tooth just half catching and the sear lever being slightly tipped forwards. Internal air pressure always pushes the trigger transmission pin down, so the trigger is no indicator of what the sear lever is doing.

Polishing the inner barrel may remove the clear anodized coating, so unless the inner barrel is scored I think you should leave it as is. Over a long period of time saltwater will eventually pit the inner barrel, especially at the always exposed muzzle end of the gun, so removing the coating will just accelerate this process. Micro-particles in the water will scratch the inner barrel again, so not really worth the effort in polishing it up and those fine scratches are too small to cause air leaks. Stainless steel inner barrels are a different matter as they have a harder surface, but you will not find them in the Italian pneumatic guns.

I took the gun apart cleaned out the old oil and grease, and replaced with 10w fork oil and silicone grease. the piston seams to pump much better now and the trigger feels a lot smoother. I am now convinced the trigger spring originally wasnt properly installed.
