Of the two, it would have to be the 29 for me. A friend has a 21, not a 20, which I've tried to shoot a bit. My stubby fingers won't wrap far enough around the grip to get a good one-handed hold. The 29 isn't good but it is less bad. 1911s suit my hands a lot better. I like 10mm but I prefer it in a revolver.

This depends greatly on which generation Glock we are talking about. The grip overal diameter changes. Gen 2 and Gen 3 are the fattest. In Gen 3 there was also a Short Frame version. THe SHort FRame means the grip is smaller from front to back meaning its overall circumfirance is reduced vs. prior models. When you get to Gen 4 in the Models 20, 21, and 40 they are also reduced in grip circumfirance. I believe they are even a little smaller or at least equal to the Short Frame versions. The original Models 20 and 21 were sized for Goliath. THe newer Gen 4 however is fine. Even my wife can grasp it decently.
