In terms of failure mechanisms there were two. First, in a Belgian best gun whoever owned this gun at some point did not depress the cocking dogs when replacing the sidelock and used rubber mallet therapy to pound it back in. The person that I bought the gun from "never took off the sideplates". So - lesson: when replacing the sideplates depress the cocking dogs first - they really such fit nicely. Anytime you have to force something STOP and use your brain. The second mechanism for failure has to what for the dogwalk.
