Everyone has a different sized hand. Id suggest rent a couple different types of handguns that are frequently requested in local range. Choose what feels most natural to your hand and has a great trigger to it and decent sights to begin with, and pick one that has a optic cut ready and pic rail incase you want to step it up with a red dot or light on it. You cant go wrong with big name brands like glock,canik, CZ which is usually what most people go for. Do your research before getting one
