I agree with all of the above, but would like to add that the Spikes stuff is still very high quality. The vast majority of folks (unless you're military, police,etc) wouldn't ever notice the difference between the two enough to warrant the difference in price. As for the barrel, The 18" is a nice compromise for what you want out of it. I like a 16in for calling and as long as possible for range work. But the 18 should do fine in both worlds, just look for a fast twist, I like a 1:8 minimum, or 1:7 if possible. And, as ICANHITHIM pointed out, you'd better get it RIGHT NOW if you can find one.
