Don't buy anything till you attend a match or two. Ask to try other peoples firearms to see what feels right to you.
Some pistols will point more naturally than others. Some people like birdshead grips some don't. Same for Bisley grips.
Some prefer Rugers, some prefer SAA, and others prefer open tops. Barrel length is also a personal preference. You'll see barrel lengths as short as 2" to as long as 12".
Same applies to rifles and shotguns.
Tricked out heavily modified guns will not make you a top shooter. Properly tuned firearms and a lot of practice is what it takes.
BTW some of us shoot for style points and compete to have the most fun.
