Since Glock changed the game, most newer guns have a low bore axis. The next step is to slim down the slides even further on the sides, and hopefully Glock will be the one to step up. The current slim was a great prototype. They REALLY need to slim down all of their carry lines especially the 9mm Glock 26 and 19 to compete with all the new slim, single stack, easy to conceal 9mms out on the market today.
I hoped this is what they would announce back when they teased us with "something new and big" but it was just an internet forum. Not new, not big.
