Mine is s Gen3 and I had the problem.
So you just need to dremel off a little bit of it?
An older gen 3 or a newer gen 3? Any Gen 3 made after I think January 2010 uses the same newer parts as the Gen 4's now use, which most people believe is why any glock manufactured after that date may have the issues.
I love Glock and would not hesitate to purchase any Glock that looked to be in good shape and was manufactured pre-2010. I hope they figure out the problems and get them fixed, but until then I have no problem buying used. You save a little money and can swap out pretty much any internals you want to basically make it new again. As long as the previous owner wasn't too wreckless you shouldn't have to replace much.
As I said, when they pinpoint exactly what went wrong, address the issues and own up to it and all these horror stories stop popping up I will definitely add a Gen 4 to the stable. If I can't trust a weapon with my life, I have no use for it in my home.
I guess any Fex-Ex store can accept it.
A FedEx shipping facility, not a storefront.
Kinkos are storefronts. If you drop it off, it must be at a FedEx shipping facility, where FedEx trucks are loaded/unloaded. FedEx calls them "FedEx World Service Center". You can search for the closest ones on the FedEx website by selecting the "Dangerous Goods" filter option under "Filter by additional shipping services and options".

(search once for your zip code, then select "Refine your search", then "Filter by additional shipping services and options", then "Dangerous Goods")
IMHO it might not be a smart idea to take a gun to somewhere near BWI.
