I need some help, i'm looking for a revolver, somthing in 357 mag, somthing acurate, fun to shoot, and something that could be used for competition. and easily carried
That's a tough call.....for target and compition shooting, a revolver with a 6" barrel is usually more prefferable, but a 6" barrel can get kinda heavy on the hip for all day carry, and if this is concealed carry, you'll have to strap it in a shoulder holster, and wear a coat or jacket to hide it.
For carry as personal protection, many choose between a snub nose model with a 2 to 2.5 inch barrel, up to a 4". Most LEO standard service revolvers were 4" models.
S&W and Ruger both offer .357 magnum revolvers with a 5" barrel, but since these are somewhat of an oddity, not many gun shops carry them in stock, and they have to be special ordered.
Your best bet would be to start with a 4" model, as it will provide fairly good accuracy target shooting, and not be too combersome to carry.
As for brand, I'd go with either S&W or Ruger. I'm contemplating the purchase of a Ruger GP-161 myself...that's a medium frame, .357 Magnum revolver with a 6" barrel, and an adjustable rear target sight. The Rugers have a heavier trigger pull than the S&W's, but they are built like a tank, and have a good reputation for long service life, and few failures.
As with the purchase of any gun, look it over carefully, make sure everything works smoothly, and that the fit & finish is good. Hold it, dry fire it, make sure it's not too big for your hands. Many times you'll know if it's right for you, becasue it'll just feel right in your hands when you hold it at arms length in a firing possition.
Good luck finding that special revolver....
