A friend of mine has a Cimarron 45LC SAA, stock gun, that he was shooting in a CAS match last weekend. It hasn't seen much work but is about 5 yrs old. The cylinder locked up. It appears the "indexing thing" that is spring loaded on the bottom of the frame won't move. It stays locked in the cylinder.
With the cylinder out, it has spring tension but pulling the hammer back, it does not retract.
Any suggestions?
