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!
