My Hellcat X2 has the same type of checkering as the Frag but the entire grip is one piece so it matches. IMO the front checkering is no where near as grippy as my Ed Brown Snakeskin or even my DW's. I like my Hellcat X2 but I don't feel locked in when I'm gripping it. If that makes sense.
I have a 50GI with the frag pattern and really like it. The traction from the pattern is good and to me it is pleasing to the eye but every one sees things differently. Life would be boring if we all liked the same things.
I was completely against the GI 15 LPI and held off for years buying a GI just for that reason, then I bought a GI with the 15 LPI and now I'm sold. I don't like the looks of the Frag and it is purely aesthetic.
But for my part of the 1911 lure is the beauty of 1911s, for me, the Frag kills that beauty.
