1) Why does my Marlin Papoose have a magazine safety? I had never really noticed this before, until I stripped it for cleaning, reassembled it, and went to function-check the gun and was rewarded by a complete absence of clicky noises when the trigger was pulled.
Magazine safeties are silly and of extremely dubious utility on pistols, and utterly pointless on rifles. Especially on takedown .22 rifles that are pimped as emergency guns for the outdoorsy crowd. If you're in some hypothetical wilderness survival situation and lose your magazine, you'll be reduced to trying to beat small game to death with the buttstock, which will almost certainly expend more calories than you'll get out of a squirrel or rabbit.
2) How come the only .22 pistol on the market that is deliberately designed for small hands is such a ruptured ball of crap? Seriously, the idea behind the Walther P-22 is great; it's small and light and sized perfectly for teaching children to shoot, but if you put a serious number of rounds through it, it will be reduced to scrap before your kid is old enough for a driver's license. For the same money you could get a vastly superior Ruger or Browning, but those are sized for adult hands.
It would be awfully disappointing to be teaching your kid gun safety and marksmanship with a P-22, only to have the zamak slide separate and undo all that money you'd spent on orthodontics...
