I've been trying to figure out whether my Joseph lang back action has an intercepting sear without removing the locks.I have looked at many pictures of various lock designs and have concluded the following: All 9-pin locks have an intercepting sear. My Lang has 9-pins not counting the screws that hold the lock to the gun. One gentleman that responded to my previous post stated that a pin only had 2 functions( 1 is to provide an axle or shaft for a part to rotate on or 2 a pin or screw to hold a part in place. Using this assumption a 9-pin lock has 3 shafts(axles) which are: 1 is for the tumbler to rotate on, the second is for the sear to rotate on and the third is for the intercepting to rotate on. The six pins that are remaining are to hold lock components in place. The six pins are for the following. Three are screws used to secure the bridle and the remaining three are screws or pins to secure the three springs(main,sear and intercepting sear). A 7-pin lock does not have the shaft(axle) or the pin or screw required for the intercepting sear. A bar action lock has the same pin functions as stated above-the parts are just assembled in a different way. Conclusion-all 9-pin locks have an intercepting sear and all 7-pin locks do not. In this discussion none of the screws to hold the lock onto the gun are included. This conclusion is only viable where all pins are visible from the outside. Please comment on your thoughts about my conclusions on this subject. All the pictures on either back action or bar action locks seem to point to these conclusions. Am I all wet?

I don't think its that straightforward. Beretta SO series have a variety of different (at least 3 types) of sidelock with different pin counts. To the best of my knowledge ALL have intercepting safeties.
Purdey locks have (I think) a similar pin count, but NOT ALL have intercepting safeties. Some use a bolted sear instead.
I don't think intercepting safeties are of great importance. One of the few accidents I know of that happened to someone I know was on a gun with intercepting safeties that fell to the ground being passed between a loader and the gun shooting. Despite intercepting safeties, the gun fired due to the jolt. One parties was injured, fortunately not in a life threatening way.
I have guns with and without intercepting safeties and don't consider one safer than the other. ALL loaded guns can go off.
I do, however respect and understand your desire to know what is in your gun. I have taken photos of locks on some of mine to allow things to be looked at at a later date if needed so that I can refresh my memory.

A Zanotti pinless has no pins at all, and it definitely has intercepting sears. It is unwise to be so categorical about guns, there are so many exceptions to the rule out there.

Note the original poster on this thread did allow for pinless locks though evidence to the contrary does show the conclusion not to be 100% reliable This conclusion is only viable where all pins are visible from the outside.

Just a few comments to clarify my first post on this subject. First of all I was only referring to sidelocks made in the UK. Many different lock designs were generated by the Italian, US, and gunmakers on the continent. I should have stated that in the first post. What I was really looking for was concensus that a lock made in the UK that has 9 visable pins has an intercepting sear. I was attempting to show there is no need for 9 pins if there is not an intercepting sear. I'm sure there are lock designs in the gun world somewhere that have an intercepting sear and use less than 9 pins, but for the UK gunmakers I cannot find a 9-pin lock that does not have an intercepting sear. Please comment on this conclusion. Thanks!
