I have an older Contender that recently failed to cock/failed to open. I sent the unit back to T-C (without grip) and they fixed and returned it very quickly. Seems the hammer spring and interlock spring needed replacement. When the frame and bbl came back from T-C, they added a note that certain Pachmayr grips have insufficient clearance for the trigger guard and hammer spring. They added that they don't fix this problem. So. I inspected my grip and there was a disturbed area at the hammer spring as well as the trigger guard area. Anyone have any experience with this? Can I hog out the affected areas? Get new grips? Thanks, Don
