Awhile ago, I purchased a two-year membership to the GSSF for $60.00 so I could attend the Glock certified armorer course. Unbeknownst to me at the time, it also entitled me to one purchase/year of a new Glock blue label pistol. Today I walked out of Vance's in Columbus with a nib Gen4 Glock 19, three mags and all the goodies which come with it for $453.69. That is $25 over LEO discount.
