I bought one 1st gen with the better ret, best lazer & fastest I've ever used , glass was very good it's held up Fantastic & still enjoy it ,Buddy bought 2nd gen with sliding red dot ,it's even smaller and faster then mine& glass was improved & it's programibility is ausome .now comes 3 gen yours improved even more ,but up goes the price, but what doesn't hey ! Just saying Not ragging.... Sure wish I could pull the trigger on one , the Qualitys built in and I for one think their Underrated by many who have not tried them ! Good luck with yur sale...
