Remington Nylon 66, hands down. Lightweight, accurate, 14 rounds on demand, absolutely dependable in all conditions of weather and environment. Gone but not forgotten, as current prices on the used gun market will absolutely verify. You can mistreat it, fail to clean it, and in spite of the fact that it needs no lubrication, it goes bang every time. My first one was abandoned and full of sand - sprayed the grit out with WD-40, and it still serves me perfectly when called upon. Absolutely amazing engineering miracle! Thank you, Wayne Leek!
