38 Special autoloader
Not as a put down, but it seems many do not hand load or read balistic tables. First if you check out the numbers on the 9mm, it is little more than an autoloading 38 special.
The Colt Mid range has become somewhat of a collectors piece, so if you must go with a 38 special autoloader the S&W M52 is about the only choice.
As a bulleye shooter, I can tell you learning to shoot 3 guns is more difficult to learn to shoot than 2 guns. So about 20 years ago almost all bullseye shooters hung up the .38 special in favor of firing the .45 auto in the centerfire match.
At one time my carry gun was a 9mm Star "Starlite". I put together a handload with a cast 148 gr. cone point over 5.0 grains Unique that would clock out at 1050 fps. The load was a tack driver.
