Was re-reading "The Girl Who Played With Fire", and a murder is committed with a Colt .45 Magnum - a revolver. By some chance have I missed knowing about this cartridge, or is this another little firearms mistake by European media?

Another mistake as far as I know.

I just recently about someone referring to a hot load in 45colt as 45colt magnum.

Or maybe the author was thinking of the 45 Winchester Magnum round?

A Swedish goof, in an otherwise well written thriller trilogy.

Yep. The movies are pretty good too. Not the US made, the originals.

I just read where someone was carrying a Colt 1902 in 45 caliber, the same gun the army used in three wars.

Have you not figured out that Sansouci doesn't have a clue what he is talking about

HUH?

might help in case you buttshot a bear.

Trivia - The lady doctor who survives in the sci-fi thriller Prometheus was played by Noomi Rapace, who also played Lisbeth in the original trilogy. She is Swedish.

I also enjoyed all three books enough to begin re-reading them, and was disappointed I didn't "catch" this the first time - but still enjoyed he book. Also, I noticed that semi-autos and revolvers have been switched in their function/identities. It has also occurred to me these "mistakes" could have come from the editor or translator?
