Though I do very little hunting anymore, most of my shooting is driven by a lifetime of hunting passion that still translates into preferences for hunting-oriented equipment. So after buying the long AP16 and loving it so much, I couldn't resist also getting a short barrel and tube. Set that up for (less sniping-type) practical hunting scenarios, including offhand shooting. Hence the non magnifying red-dot sight, that I consider the best arrangement for most offhand pistol shooting.
But after using the shorter, red-dot set-up for awhile (and not hunting with it yet), and missing the long-range precision of the longer, 2-7X scoped set-up, I swapped back to that. Not sure why I love shooting air pistols at 50 yards so much; probably just one of my many bizarre idiosyncrasies. Regardless, I love powerful guns, particularly powerful air pistols, and especially, powerful air pistols that shoot sub-1" groups at 50 yards.
But should I have the need or desire, it's nice to have the option of swapping to the shorter arrangement in a couple minutes, and knowing it is already sighted in. Call me crazy...
And I'll answer to that.
