The Stock 3 is the longer slide member of Tanfoglio's Stock family, made for sport shooting. Its owners usually tune three areas: the hold, the reload and the sight picture.
The hold
Toni System's aluminium panels are textured for grip, and the long and short versions decide how far up the frame they reach. They are in Grips for Tanfoglio Stock 3.
The reload
Grips, magwells and pads exist in Small Frame and Large Frame versions. Magwells come standard or open, and aluminium pads add one, two, four or more rounds; the longest suit open style setups. See Magwells for Tanfoglio Stock 3 and Base pads for Tanfoglio Stock 3.
