Ok to own/practice with diff cal handguns?
I know that there are plenty of ppl on this site with the mindset that more handguns = better but I was wondering if it's a good idea to have a couple handguns that are different cal. I used to own a .40 cal and then I got a 9mm. I was dead on with the .40 but when it came to the 9mm I was compensating too much because I learned on a .40 cal and couldn't correct it. I am now getting used to the 9mm but I miss having a more powerful handgun. Would it be "not wise" as a beginner (about a year or so experience) to own a 9mm, 40, and a 45? Would that mess me up altogether? The guys at the range told me to pick one gun and cal to practice with and to carry.
