Well it seems my hammer extension has caused the hammer to peen towards the frame. There is now a small crack. I noticed it late muzzleloader season , and would like to get it repaired or replaced. The extension was aftermarket and It may be stainless. Has anyone else had this happen, or had this repair made? If so, was it returned to thompson? The pet load has been 63.2 grains ( by weight) BH 209 with a 250 grain Lehigh bullet. Thanks in advance, Jason.
