Ruger vaquero vs. ria 1911 vs. springfield 1911?

i want to get a pistol not for home defense but just for fun. i want it to be a larger caliber because it adds more excitement to shooting. i would like a cowboy type of pistol for accuracy and reliability ( ruger vaquero) but i would also like a 1911 for reloading practicality and rate of fire.if i get a 1911 should i get the rock island armory gi or the springfield gi?
