I would rather tend to go for a pistol, where you can put alternative grips on.
That way, you are flexible on the firearm and you can adapt the size of the grip to your hands.
I have the reverse problem. My hands are rather small (short). Therefor I have problems with the Pachmayr and Hogue grips on my CZ75. So I was looking for a pair of grips, that are slim enough for me and found them in the Trausch grips (Trausch Grips
So you would need to look for the oposite type of grip.
Most firearms have double row mags. That makes the grip itself thicker then on a classic 1911 with a single row mag.
So, you could look for a Sig Sauer P226 or 228, (the grip is bigger then on a 220) and put a Pachmayr Signature Grip on it. That should give you a good grip for your hands, I owuld say.
Taking pistols in a Glock style, makes a bit harder to adapt the grip size to your hands, as you can mostly only put a sleeve like the Hogue Handball over it.
Or you can go for a Walther P99 or HK with interchangable grip parts.
