There was a GLOCK group buy on this board that ended a few days ago. Price was ≈$515otd iirc. There might be another gb like it in a month or so.
took in a used glock gen 2 21 (95%+ real nice!) CASH buy it for $425.00 out door! 2 mags and original box!
Around $550.00 new for Gen 4...maybe a bit cheaper.
