I understand that the Glock is a tool like any other but a pretty hammer drives nails just like an ugly one. That being said, I don't think the "new" look is working for me. I would really like to see them adopt the slide profile of the smaller 26/27 to the bigger Glocks. It not only looks better but the tapered slide does have function as well. The texture of the grip on the current models I thought was pretty smart. It had aggressive checkering on the front and backstrap and smoother sides that ride against your body. If you wanted it more aggressive a wood burner fixes that in a jiffy. I have a few M&Ps. If you want to feel a slick grip shoot an M&P compact. I like the shape much better but the texture is pretty useless. Shape also plays a role though. My HiPower has smooth grips and it fits my hand and doesn't feel slick at all. The same with my M&P fullsize. It fits your hand and feels locked in without aggressive texture. There has to be a way that Glock can come up with something better than this new stuff.
Also, the slide serrations on the M&Ps are nice looking and very positive. Several smaller curves does the job better than one big one I would think. I'm sure either way the Glocks will still be great no matter which way they go.
