This is a fantastic bulletinboard with incredibly knowledible shotgun owners and I would like your input on a recent aqusition. Just recently purchased a used Spanish gun, Davidson's model 63b which some of you are familiar. Very well made A&D action with side clips, greener bolt, bushings. All screws timed even butt plate screws. The only thing frustrating is that it cocks too early making it difficult too load since the barrels rebound due to mainspring. I would like to carefully take a needle file and remove a few thousands of material on either the cocking levers or forend notches (preferred)to delay cocking a bit to allow the barrels to swing open more. I only have $300 in the gun but would like like to resolve problem. Anyone's thoughts who have done this?

I'm having an L C Smith corrected now, at Jim Kelley's shop, that has the same issue. I've never done it myself, but there was a thread that I started about it recently that might interest you. Sorry I can't help with the hands on part.

It will be much easier to work on the cocking levers than the notches in the fore end. The extractor cam often works as a barrel stop. Watch that and the hammer bent/sear inter action. The last thing you want is to go too far and have it not cock. Best of luck.

Steve, are either of these surfaces typically hardened? I will for sure take it slow and ckeck frequently. Due to geometry a few thousandths there will make a big difference.

The fore end iron is likely case hardened, not for sure though as some are just blued. The cocking levers should be moderately hard. Usually made of a type of tool steel, hardened and then tempered. They should be able to be stoned or filed but not dead soft.

Since I will be abe to have some control is it more desirable to have both hammers cocked at same time or have slight offset? I guess another way of asking is would a higher quality gun normally cock at same time. time?

This design feature was to insure that shells do not fall out when the gun is carried open. I don't really understand the inconvenience of loading when the gun is in the position the poster mentions.

The inconvenience is when you have to manually hold open the barrels in order to load as opposed to let gravity due the work. I have heard this argument before about this was design intent to keep shells from falling out when carried open. I don't know about everyone else but when my gun is open the barrels are pointed down and the shells will not fall out due to the laws of gravity. I can't think of a scenario where the gun would be open and the barrels would be pointed in such an angle (when loaded) the shells would fall out.
