I am looking to purchase my first handgun in a few weeks. I have been looking at the Glock, Springfield, and M&P. This isn't a thread on which one is the best because I've read many times on here to choose the one that feels the best to you. My problem is I haven't chose a caliber yet and don't think I will truely get a proper conclusion by chosing one gun in one caliber and another in a different. Should I go one day and rent all three in the same caliber to chose the right manufacturer and then go and shoot the different calibers? Or will choosing one in each caliber be a decent way to choose also.
Any help will be appreciated as this will be my first handgun.
Thanks
