I agree. I think we're up to date now. "Generations" of the Glock pistol generally involve more sweeping changes rather than minor adaptions. Physically, and functionally. Any time Glock adds a part or parts, or re-contours the frame physically from the original, it's a major change and worthy of another 'generation'. Three pin frames, two pin frames, finger grooves, smooth grip, etc...... The manufacturer is the one that actually determines a generation change, and it's usually publicized as such. Glock likes to keep things stirring amongst the fans......it's interesting, and it boosts interest among the new and die hard fans. Now they are wisely catering to the hold-outs and consumer input. Any great company will remain at the top while adapting to change. IMO, Glock doesn't need to make any changes to stay at the top. Thinking about the Glock pistol generations is rather simple compared to deciphering the magazine changes and upgrades made over the years. When Glock makes a big change to their pistols, it's all over the world. To me, that's good publicity, and catches a lot of folks attention. Whatever changes Glock makes, and no matter what we think of those changes individually, just simply insures that Glock will remain at the top of the list for years to come. Just the word Glock indicates a sweeping change....of history in the firearms industry, and what folks choose to be their best, most user friendly, and dependable pistol for concealed carry, top line security, law enforcement, and combat pistols world-wide.
