I'd try as many calibers as possible. .380, .38 (they're same size but different), 9mm, .357, .40, .45. Technically, .380, .38, .357 and 9mm are all the same size (bullet that is) but the cartridges are different so they range in the power of the cartridge.

I'd also try different guns, brands, sizes, etc.... For sure, I'd try a 1911. It's a classic. I'd also try a plastic gun or two. Try a revolver or two. Try some of the tiny pocket guns.

I got lucky, another Pelican took me out shooting for my first time ever and had quite a collection. I then put together another outing with a variety of guns.

Pay attention to how comfortable they feel in your hand and to shoot. Pay attention to which ones you find it easier to fire accurately.
