we will never see a product like this, we will see a carbine sooner than a glock with adjustable grip. ive been to the glock plant in the USA, and ive talked with guys from glock gmbh. they really have no interest in this. from what i understand, the company looks at it like this. you want a gun with adj grips get a HK or Walther. it would cost them way too much money to develop ,do this . and put the glock pistol in a higher priced pistol category like the Hk pistols and even the walthers. And for some reason they dont even think the S&W M&P is even a contender to the glock. they think it is a good gun . but its not a world gun like the glock, you can get a glock in every part of the world but you cant get a M&P, and glock already have their US market , so why worry about a tiny part of the market for huge change in manufacturing. i would love to see one too, but it just aint going to happen. btw i have a M&P as well as several glocks. the M&P is a very good pistol, but its not a glock. I still like it and shoot it quite a bit.
