Theoretically, push off is only a problem if you shoot single action. If you only shoot double action, it is not a problem.
I would suggest, however, that if the single action feature is still in the revolver, then you should either: (1) have it PROPERLY repaired; or, (2) completely remove the single action capability rendering the revolver DAO.
Even if you are the only shooter, if you have it cocked, and it gives way, you best hope that the shot goes harmlessly down range. Sorry, but the push-off condition is so potentially dangerous, i.e. the weapon could fire when you do not intend, it is just not worth the risk. Get it repaired for your sake and the sake of everyone who shoots with you or near you at the range.
