Still loading old school like me or maybe you like to keep slugs and buckshot in separate carriers. These CNC machined aluminum shotshell caddies from Advance Ratio Sports are just the ticket. They also have our favorite logo and signature on them. Includes hardware and stainless steel belt brackets to fit 1.5" belts but are also drilled to accept BladeTech TekLoks and Safariland ELS forks. Each caddy holds 4 shells which are secured with leaf style springs.
I would recommend removing the four screws that hold the retention clips in place and putting a drop of loctite on them.
