Do you see Glock diversifying it's product line anytime soon...maybe rifles or carbines?

It could make sense. The firearms industry is one of the few industries today that has growth potential. But one of the keys would be the product concept. Perhaps a marketing campaign based on the one cartridge for both handgun and rifle concept, and draw a parallel between the rugged and wild old west and today's turmoil and uncertain future. The rifle or carbine would need to use the same Glock magazines and fire the same pistol calibers. The guns should be modular so that you could convert it to fire any of the Glock calibers. Barrels can be interchangeable and screwed into place like the Uzi. A select fire model can be sold to law enforcement and the military. Such a rifle could spark the re-birth of the 10mm by offering near 30-30 ballistics. Even the 9mm would see a significant boost in velocity from a 16 inch barrel, drawing comparisons to .357 mag handgun ballistics. The marketing campaign would also need to stress the improved ballistics. The big question mark is the economy. All bets are off if/when the USD collapses.
