I have seen some fake pins...don't think any were Brit...although I wouldn't say they don't exist...would think they would mostly be found on cheaper knock offs of higher quality guns....

lets not forget blind pin guns where none of the pins show on the outside....hard to tell them from a side plated boxlock.....

The story I was told was bar action locks in theory will have a better trigger pull due to the way the springs pressure is applied to the sear making it the better system....
