The 3 shot extension gave me 15 round total for home defense. I put a minibuck 2 1/4" in the camber and 14 Federal shorty shells or Aguila minishells with buckshot.(1 3/4" shells) They fit and cycle perfectly in the Winchester 1300.

In the past I had looked for an extension tube for my old Winchester 1300 and didn't have much luck. This Sure Cycle 3 Shot Magazine Extension looked good and sounded good so I took the plunge ordering one. I couldn't be more happy, it was a breeze to install and it works smooth and easy as can be.

Did as advertised, extended the Winchester shotgun from 4 to 6 shells (run one short to not bind the spring). So far no hiccups.

I absolutely have 3 extra rounds in my savage 320 but, there isn't enough spring to cycle tha last 2 to 3 rounds. Got a long spring (45in) from wolf springs and now its perfect.

The only thing i'd say is that it looks kinda funny on a shotgun with wooden furniture.

The original end cap has a swivel. There is no hole for the swivel and the cap looks too flimsy, capped in plastic, to drill out. Had to purchase a mount to get the swivel back. Be aware when ordering. Other then that it seems beefy enough.

The first item sent to me had some discoloration on the finish. I reported it and customer service corrected the issue faster and easier than I've come to expect these days. Really apricate it. The product itself is a simple design and install and fits the purpose great. VOTE DEMS OUT! TRUMP 2020! VOTE RED ACROSS THE BOARD
