I own a Benelli Super 90 Macino, Superlight, semi - auto game gun (left hand) - have it for the past two years and no problems to date. I fire 3,000 - 3,500 cartridges a year - rough shooting, game shooting, decoying and clays, and the gun has never jammed once! Also the gun can take loads from 28 gram to 56 gram with no alterations. Cleaning is a doddle as there is no gas piston, the cycle works on recoil - thorough job takes about 20 minutes every 1000 cartridges fired.
For left handers the only semi - auto available are Benelli, Remington and Fabarm.
