I put a GRT-III trigger in my Gamo Whisper, and had a little trigger spring left over. I was really pleased with the improvement.
Soooo, when I had the Crosman Titan NP apart to tune and replace a piston seal, I thought I wonder what would happen if I just take out this little trigger spring? The Titan had a gritty, long trigger pull.
Now, it has a very short hair trigger, and a trigger pull probably in the low ounce range. I polished the sear surfaces, too.
From one extreme to the other, possibly dangerous.
I think I'll get some small diameter music wire and make a lighter replacement spring.
Can music wire be annealed, bent to shape, and re-hardened? |

The only thing that little spring does is to return the trigger to its full-forward position. The trigger swings through a long arc without touching anything, and then suddenly you're pulling against the combined force of the trigger spring and the strut spring (intermediate sear). The GRT trigger uses the strut spring for its whole length of travel.
As far as being dangerous - the original so-called "adjustment screw" works by disengaging the sear. Screw it in too far and you can leave the sear hanging by a thread, but that's no different than it was originally.
As with any springer, you should always have one hand on the barrel/cocking lever when loading, and always keep it pointed in a safe direction. |

Thanks for the info. I shoot it safely enough; never cock and load it until I'm ready to shoot. However, the trigger pull is so light, I'd be a little worried about setting it down too hard, say butt first, on the floor, because just jarring it might be enough to discharge it. I don't handle it in this manner anyway, nor does anyone else shoot my airguns, but I would like to have about a two pound trigger pull. Can I get a light aftermarket spring for it, or do I have to make my own? (Which I can do, if need be.)
Meantime, it's a real pleasure to shoot it as is... |

Go to "Custom Triggers" then select "GTX". |
I stand corrected, the CDT trigger is not the only alternative. Except - the GTX trigger will not fit the newer Gamo plastic triggers. Instead, on that same site look for "Gamo PTG Mod."
The GRT-4G is a complete replacement trigger. The PTG Mod is a little piece that is added to the original plastic trigger. The PTG is less expensive, and is not adjustable. Both alternatives use the same geometry and both delete the trigger spring. The difficulty of installation appears to be equal for both. |
