I picked this up around 2 years ago.
The first few runs of these were marked USMC on the slide.
For whatever reason (rumor had it that the Marines made them take it off of the civilian model) USMC was removed from the slide and replaced by "M45A1".
Due to the relative rarity of the "USMC" marked handguns, they went up in value.
It kind of pissed me off on one hand because I bought it to shoot.
Now I cant shoot it for fear of ruining the value.
I did shoot it once and I was hitting bull's eyes and had a real tight group.
I love this gun.
I may have to pick up a M45A1 version to shoot.
And yes I wear gloves when I handle my collectible firearms.
Call me a wuss but I dont care.
