For me, the grip angle isn't as much an issue as the shape and width of the grip. A Glock doesn't fit me particularly well because they have fairly wide squarish grips. My 1911 has a flat mainspring housing, but my brother's Colt with it's arched housing actually fits me a bit better likewise I replaced the flat-backstrap grips on my S&W 1076 with the curved palmswell type. Generally, I like a thinner more rounded grip on an autoloader which is why all but one of my autos are single stacks (SW1911, CZ-52, S&W 1076, and Walther PP, my CZ-75 is the only double stack). A few double stacks like a my CZ-75 or a Walther P99 fit me well but several others like a Glock, Sig, or XD do not. On a revolver, finger grooves and a palmswell fit me the best. Three of my five revolvers wear Houges. The other two (a Colt Cobra and H&R Sportsman) wear factory stocks (the Colt also has a Tyler T-Grip adapter) but they don't fit me quite as well as my Houge-stocked revolvers.
