The rise of the plastic guns along with the increase in costs to produce steel pistols.
Glocks started showing up in the U.S. around that the time that S&W 3rd generation pistols were introduced in 1989. By 1992, both seemed to be fighting hard for attention and buyers' dollars. Glocks seemed to increase in price very slowly while 3rd Gens rose more quickly. Now it seems like it's become a plastic world. Is that progress?
