haha, what is the "best handgun for shooting?" that varies greatly from one person to the next, and also what kind of shooting you are plannning on doing. What feels nice in my hand, may not in yours.
I like revolvers a lot, single and double action for fun shooting, accuracy, and long range (for pistols), surplus Tokarevs are super fun and economical for going to the range and burning off lots of ammo, 1911 pistols are really fun, fit my hand great and get super groupings, and a modern 9mm is just the thing for a lot of competitive shoot formats, plus ammo is cheap for them.
