Q: I heard that someone used a spring from an ink pen to adjust their trigger pull on a Marlin 915.

A: That method is not recommended because it's an unsafe modification to a firearm with a component that wasn't intended to function in a trigger assembly. We do not recommend this. It's not worth potentially injuring yourself or worse, someone else.

Q: Should I be concerned with any malfunctions or light strikes after installing this kit?

A: No, all of our M*CARBO Trigger Spring Kits have been professionally engineered, designed and manufactured to reduce trigger pull while maintaining 100% reliability of the firearm. You will not experience any sort of light strike or malfunction but you will experience a crisp smooth lighter trigger pull. Guaranteed or your Money Back!

This is exactly what I needed for my model 883. Along with a polish my trigger is nice and smooth and down to a 2.25lb pull. My thoughts on pen spring "trick" is: If you have a 50cent gun then put a 50cent trigger in it. Really y'all? A bic pen spring in a gun?! What you thinking?

Great upgrade for my Marlin 881

Pros:

I struggled for years with the exorbitant heavy trigger pull of the stock trigger in my old Marlin 881 which no doubt effected the accuracy. I had performed the clicker ink pen spring mod which helped but was leery of how safe the pen spring mod was so I quit procrastinating and ordered the Mcarbo trigger spring. Words can not express the day and night difference this spring upgrade made in the reduction of the trigger pull. I do not have a scale to report the difference but it is now smooth and light. This spring upgrade has transformed my old Marlin into the tack driver it should have always been.
