TC Contender Hammer Springs need periodic replacing with a fresh Bellm custom hammer spring, CNC manufactured in the USA.
Contender hammer springs fatigue over time and should be replaced periodically. If the headspace is correct as measured with our Headspace Indicator, the ammunition is good, and the lockup is complete, misfires suggest it is time to replace the hammer spring.
This is fairly easy to do and does not require complete disassembly of the frame. Take the grip or buttstock off the frame. Remove the largest pivot pin from the frame, the hammer pivot pin. The hammer comes out the top of the frame.
Easiest method for reinstallation is to cut a short section of rod to fit inside the width of the hammer and install the spring into the hammer. Install the hammer into the frame and tap in the pivot pin. The short "assembly pin" keeps the spring in place while the pivot pin is driven in.
In the shop I simply put the frame in a padded vise being careful to clamp over a supported part of the frame so as to not crush the thin sides of the frame, insert the hammer into the frame, line up the holes with a punch and capture the spring with the punch from one side while I tap in the pivot pin from the opposite side.
It is a bit awkward, but not hard to do. Just push on the coils from behind to line up the opening in the coils with the pivot pin.
Stainless and blued frames use the same spring in all models of the same type.
Note: These are our own manufacture TC Contender Hammer Springs, not TC factory issue.

If you have a G2, click here Springs for the G2 are the exact same as used in the Encore/Pro Hunter/Endeavor frames. They are a large coil spring, much different from the formed spring used in the Contender.
