Hi Just wondering if the Kahr 1927a1 firing pins will interchange with a 1980 manufacture West Hurley 27A5 that was made for the long Type 1 firing pin. My greatest concern that if the Kahr product is used,that any excess tolerance might crack the bolt face. Currently Numrich has only the Type 3 pin in stock and the tech claims both the Type 2 and 3 are compatible, however I am not certain if the so called "Type 1" pin is in reality the correct nomenclature for the long stem firing pin? In any case since having broken my firing pin, it has been nearly impossible to locate one of the identical types. I purchased one of the older "nub" type firing pins but they do not clear the firing pin channel. am curious of what to do, or a source for one of these firing pins. May have to ultimately try a precision machine shop to have one made. Thanks. George
