A lot of that is probably accounted for by merging threads. There was also a short time when we had a mod deleting threads. And then of course, the was the Great Crash of 2008. That could've impacted the thread ID also. And lastly, some of those ID's (like user ID's) got jumbled when we migrated from phpBB to vBulletin way back when. Long story short, don't trust those numbers to mean anything.

Best thing to do with the LCPs is exactly that; go put a couple hundred rounds through it. They're much smoother after being broke in. They're very stiff when new, and don't like hollow points. After being broke in, they'll shoot anything all day long. FYI.
