^Why would a CMP employee with access to literally thousands and thousands of unused stocks go break into this guy's alarmed car to steal one?
Let's take a logical look:
1. Your car was not broken into. You would know. There would be damage, you were hear the alarm, etc.
2. Your hotel room was the most vulnerable place your Garand was during the trip. Many people have access to it and are even expected to access it daily.
3. You loaded up your Garand the
night before. I don't know about you, but at night time those stocks probably don't look too different to me. Especially if I have a lot of guns to load.
So, assuming this isn't all BS, I am about 85% sure your Garand stock was swapped at the hotel sometime.
The question: Why steal a stock and not the rifle?
The answer: The thief is a Garand owner, meaning probably not a serious criminal (they usually aren't into C&Rs). The saw your stock as a crime of opportunity. Stealing your stock is likely a low level misdemeanor and hard to prove. Stealing a firearm is a federal felony that could net you ten years in prison and is much easier to trace.
But that begs another question: Why not just steal the stock and leave the barreled action laying there? Why take the time to leave a stock for you?
The answer: Like I said, the person probably isn't a serious criminal, so there may have been some level of guilt. They probably didn't want you to have a non-functioning rifle and they justified it by leaving their stock on it. This is akin to the people who shoplift, but still pay for half of the stuff (this happens ALL the time).
You just got really unlucky. The person had to be an owner, as my girlfriend who shoots with me probably still wouldn't know your Garand is the same as my Garand by looking at yours off hand. What are the odds of a Garand owner being one of those people with access to your room? Much less a shady one? Very slim. Buy a lottery ticket.
As for the stock itself, personally, I think the thief did your 1943 Garand
a favor
[Plus now you have a cool story to tell your shooting buddies forever]
