I will be acquiring a Colt 1991 with the Series 80 firing pin block. Is there any special maintenance or function checking that I should perform on the Series 80 system?
Many people express concerns over reliability of this system. Is it any less reliable than the firing pin safeties on modern Glocks or Sigs? I get the whole "JMB didn't think it necessary" thing, but it seems that one additional layer of drop safety has merit as long as it is reliable.
