My dream Glock mod would be a Glock 27 (sold mine...fuggin idiot,) with the 9mm threaded /ported/ extended barrell, can, and the nice old stocks. Why? Because I would love to have a pistol that could go from subcompact concealed to multiple ammo types to mini uzi without any tools. But I also admit that I love Glocks, and am totally irrational with my mod dreams.
