GLOCK markets their handguns as exemplifying perfection — a claim that their sales numbers would seem to support. Improvements on perfection are always welcome, though. Last year GLOCK came out with a new twist on their existing G17 and G19 lines, expanding the “MOS” or Modular Optic System to these most popular models they make. We got our hands on some samples ahead of time for a review and Jeremy absolutely loved it, making the G19 his new everyday carry gun. It looks like our readers agree and have namedthe G17 / G19 MOS 2016’s Reader’s Choice Award winner for Best New Handgun.
