Our shotshell caddies utilize our proven 303 Hi-Yield Stainless steel leaf springs to contain either three or four 2 3/4 in. 12 ga. shells in their slots, depending on model. The 303 springs provide excellent retention, yet also provide for a silky smooth grab. All our shotshell caddies are drilled and tapped to accept the most popular belt attachment methods in the industry - the Blade-Tech Tek-Lok, Safariland ELS, or Blade-Tech MOLLE attachments. The 4x4s and 3x3s are the most efficient use of belt real estate on the market. They have become hugely popular in the sport of 3-Gun Practical Shotgun Competition, since their introduction.
