"why are so many up for sale??"I'm sure the "block" nuts are going to come from every and cranny in horrible indignation, but if "blocks" are do great, why are so many up for sale?? I have tried them and find no such fascination about them. Oh well, guess I am just " block snobbery" material.
Because there are so many more of them in circulation than any other handgun. G19 is the most popular CC weapon in the world. G17 and G22 are the most popular LE weapons in the Western Hemisphere... at least.
