Try before you buy. Go to a range that rents. Almost all modern guns are accurate and reliable. It's all about features and manual of arms.

I will say this: if you have a dozen guns, spread out over all calibers and manuals of arms, and spread your practice time among all, you'll get decent with all, but not really capable on any one. And if you carry a variety of guns, it gets worse, since you won't have a lot of total-immersion type training and "muscle memory" (for lack of a better term) to fall back on. Experimentation is fine, but at some point, there's something to be said for settling on one package/caliber. Just a thought.
