After seeing detachable magazines fall out in water puddles and deep, soft snow after the first shot was fired, I am convinced they are a liability, so prefer hinged floorplates on my centerfires. Rimfire is a non-issue, detachables are OK there. I have also seen several cases of lost magazines (some very expensive to replace!) at the worst possible times. Another objection I have for detachables is the lint, dust, grit and crap they seem to accumulate if carried in a pocket. I don't care for that stuff in the chamber of my rifle. Some detachable systems are true abortions as well (someone mentioned the Kwik-Klip conversions and I would add the Browning A-bolt design as well as any detachable that has a release so small that it cannot be readily released when one has gloves on) Regards, Eagleye.
