I bought my Glock 19 in May 89. Serial number is ER 55X. Shot less than 200 rounds, still have the numbered box, warranty cards and manual etc. Went to Europe in 90 and returned to a handgun unfriendly state. Stored it for years. Now that my state has defrosted its gun laws I got it out. Is this gun a 'first generation' or a second? Value guesstimate? Thanks! Don Wanna kill these ads? We can help!
