There is a remarkable difference between the grip of a Gen 3 and RTF2. Glocks have always had a bit of a slick feel to me, but the RTF2 sticks. Once you grip it, you own it - it's a very positive grip, probably on par with or exceeds the 'sandpaper' panels a lot of people use.
I've read a lot of comments complaining about the curved cocking serations versus the gen 3 style straight cocking serations. I like 'em - I like 'em better. I like the way the look and grip. Anyway...
I love the grippiness of the gun; I haven't shot it yet, but maybe by tomorrow and I'll see what the grip feels like in recoil.
I can say right now, I fully expect that if one were to take an RTF2 to a 5 day shooting school, you should expects some raw places. One place, and this could be easily fixed is the raised portion of the thumb rest on the right side. Because it's raised the pyramids become abrasive to the base of the thumb. Wouldn't be a problem at all in a defensive situation, but if you did a lot of draw and fires, and I do, it won't take long to make a tender spot. Can't wait to shoot it.
