Good morning. I have examined a first variation of the T/C Patriot pistol. It has an interior Spring loaded Detent ball which keeps a bit of pressure on the ramrod. The 2nd variation Patriot went to the retention spring. Given a choice, I would prefer the spring loaded detent ball. It rolls with the insertion of the ramrod and seems to last forever given proper maintenance.
If one has some basic machining skills, one can make the detent ball/spring with a set screw, spring, and ball. then drill and tap the rib above the ramrod. Think about the ball catch closure on a closet door. It is a spring loaded ball detent inserted in the top of the door to pop in and out of a slot. Make one of these ball catches in miniature.
HC police please avert your eyes, this solution may not be HC.
Kind regards,
