I started this thread with a revolver and .357 bias, but probably because I only plink and need home defense, I have switched to preferring .45 ACP, particularly the Springfield XD .45 ACP 4-inch tactical model I bought.
In fact, the XD has become my favorite gun. Accurate, lightweight, reliable, affordable, versatile, it's perfect for my needs.
4-inch barrel, 13-round magazine, Glock tactical light with laser, less than 3 pounds loaded up, good accessories right out of the box, excellent ergonomics, I'm amazed how much I like the XD .45 ACP.
I was also surprised to realize that I really don't like firing .357s. I respect the round, but don't like shooting it. Nor do I like shooting revolvers; much prefer semiautomatics.
I always thought I preferred revolvers, but I don't. Hmmm. Wonder what else I think I like but don't? We never live too long to outgrow our surprises.
