I'm a huge fan of the .38 Super round. I've had (or have) .38 Super guns from Colt, SVI, STI, Kimber, and SIG.
.38 Super and .45 ACP are my favorite rounds. While I have some 9mm handguns that I love, I get a little bored with them. I tried .40 and .357 SIG to get a little variety but they just weren't "it" for me. Finally ran across a .38 super and just fell in love with the round. It's just plain FUN!!!
I don't compete & I don't reload...just shoot at the range (a lot). If you don't reload, you probably do not want to get a "race gun" in .38 super since they function best with longer loads than you'll be able to get from factory ammo. With that said, my SVIs and STIs were absolutely stunning guns. My Colt & Kimber were 100% also at a fraction of the cost. Haven't shot my SIG yet (in fact I'm just in the process of buying it).
