Acquired a Mauser pistol that appears to be a late model odd ball. Box reads "Renato Gamba Mauser HSc-80 and was last sold in 2009. Its a 12+1, .380 semi auto, rich blue in color. Its double action pull is horrendous and single action somewhat better It's in good condition and has the "US" style mag release on the left side. Any info on the gun would helpful.
