How to Lighten a Trigger Pull

[TheBear]

I found my old .20 cal Sheridan C9 air rifle in my basement yesterday. I loved this gun when I was a kid.
I still like it a lot, its pretty accurate and powerfull but I just hate its trigger, it has a massive pull and a hard break. I`m sure everyone who ever shot this Rifle knows what I mean.
Is there any why I can lighten the pull by myself without having to go to a gunsmith? Maybe some step by step guide or something?

I don't know if it's because airguns are less expensive, on average, than firearms, or if it's because the mechanisms require special tools (as for compressing big springs), but there are a lot fewer airgun gunsmiths than firearm gunsmiths, and they are more specialized. You can try lubrication and a trigger shoe to make it feel lighter, but unless you have a ready source of affordable replacement parts for when you mess one up, you'll want to send it to such a specialist.

The simplest thing you can do is to replace the trigger return spring with a similar spring that's not as stiff. That usually makes a big difference.

Remove the stock (large screw in front of the trigger guard) and tap out the pin holding the trigger in place. Be sure to prevent the trigger spring and trigger stop (small piece inside the spring) from escaping.

Replace the trigger spring with the lighter spring, being sure to put the trigger stop back in place, reinstall the trigger pin, put the stock back on and you're good to go.

If you want, you can very carefully polish the engagement surfaces of the trigger where they contact the cylindrical "hammer". Don't round the edges or corners.

When you're done, lubricate the contact surfaces with a tiny dab of light lithium grease or a good quality oil.

Test it a few times by cocking the bolt without loading a pellet to see if bumping the stock on a carpeted floor butt first will cause the trigger to trip from the impact. If it does, a slightly heavier spring is in order.

MAC-1 has a good reputation in the Sheridan community. He can do just about anything you want done to a Sheridan, including some things you may not have realized you NEED.
