I ordered a brand new glock and received it today. I assumed since I ordered an G23 RTF2 that it would have the "cruved" serrated slide but when I opened the box, this is what I got. I called glock to make sure it wasn't a mistake from an Gen 3 but the guy from Glock told me that they moved away from the "curved" serrations since they were really "slippery when wet" I have been to many stores in Utah and no where could I find a G23 RTF2 so I ordered one and this is what you see. The date from the factory states "Jan. 20, 2010" so it is only 12 days old. What looks better the straight or the curved serrations on the slide?
