One or more of the chambers may already be cracked.....

No worry. The serial places this gun several years too late for this to be a possibility. The aluminum cylinders were a thing of the early years and the experiment was over by 1954 or so; I'd have to look up the exact year. Of course, the advice about +P is good regardless.
PS: Looked it up. According to the SCSW, aluminum cylinders fall between serials C190000 and 310000, all in the pre-model period. So C58xxxx is well clear, and in fact all Model 12 stamped guns should have steel cylinders.
