I love the 45ACP...I see the 357 as an almost overlooked round in these modern times. Wheel guns are seen by so many as the old way and not of any real use...Unless they have one pointed at them and they run and pray. I love my two Smith 357's. There is simply no denying it's effectiveness as a defense round.
I'm also kind of confused by the blind 9mm love. For me a 9mm makes a pretty fun target gun but I don't like carrying them around all that much.
Shooting fun I'm a rabid 22LR fan. The cost per round is just sooo overshadowed by the fun I get form shooting them. Pistols, revolvers, rifles, all tons of fun in 22.
But carrying I stick with a 45ACP for the most part. I did recently aquire a 9mm that is very carry friendly and do like it but am much more comfortable wit ha 45 I just seem to shoot them better.
