I was checking the serial #'s on my dad's Combat Commander the other day to get the mfg date and discovered a small hairline crack in the frame as you can see circled in the included pictures. I'd like to get any advice INGO members may have as to how much a crack like this effects the weapon's functionality and safety, as well as any means possible of repairing the problem if possible. I understand the most simple solution would be to purchase a new frame but as this is an older model I would like to repair it if it can be repaired. Or possibly gauge what kind of value it may have in this state. I'm thinking it may be a really good looking paperweight at this point but I'm hoping somebody can tell me otherwise.
