I have purchased a SigMauser M2 in 45 caliber. How many are saying "what is he talking about,that cannot be right". Sig Arms and Mauser are different companies. This pistol has not had the bluing shot out of the barrel crown. I have run 200 rounds thru it without a malfuntion of any kind. Because of the pistol's rarity,I will only use it in a last ditch SD.

Considering Mauser is owned by Sig at this point and has been since 2000, I figure those whacky Europeans can call it a SigMauser if they want.
