I have a Gamo Swarm Maxxim Gen2 and it's been a great Squirrel Gun. However I now have 5 magazines for it, and only one works. When I try to load the magazines the pellet falls through. I have tried 3 varieties of Gamo pellets,, H&N and Crosman Premiers with the same results.
I think that the rubber retaining ring stretches and loses it's ability to hold the waist of the pellet.
The Gamo Customer service folks wee very sympathetic and sent me 2 new magazines. Worked great 2 or 3 times and now they are dropping pellets too.
Has anyone else experienced this? Is there a fix? I am thinking of tearing one apart and putting a rubber band from my desk.

I finally gave up and removed the reloading mechanism.

Some of the Hatsan PCP magazines use an o-ring to retain pellets. It looks like the Gamo magazine uses a similar o-ring for pellet retention.
If you disassemble one magazine and take some measurements of the existing o-ring AND the groove ID you can usually find a "dash# inch dimension" or a "metric" o-ring to replace a worn/stretched/broken one.

I usually start at McMaster-Carr just to identify which SIZE is a best fit. McMaster-Carr pricing is usually pretty good and delivery is usually very quick but there is added shipping cost. I always check Amazon for their pricing with free shipping. I have purchased o-rings from BOTH sources. O-rings should NOT be expensive. I usually get bags of 100 and rarely pay more than $5-$12 /100.
NOT a Gamo... but I've recently experienced the convenience of a multi-shot springer... AND the FRUSTRATION when the autoloading mechanism fails.
If a simple o-ring replacement fixes the problem I would be DELIGHTED. In my case there is no simple fix and removing the autoloader completely disables the rifle :-(

It's easy to fix the Gamo Swarm magazines when the rubber retaining ring stretches or breaks and the pellets are loose and fall out. Take out the tiny Phillips head screw in the center of the magazine with a size 0 phillips screwdriver. Remove the rotating hub that the pellets fit in and replace the rubber o-ring that goes around it and holds the pellets in place. I took the hub to Ace hardware and bought a 1& 1/16" O.D by 15/16 "I.D o-ring and it works fine. It was a gen 2 magazine.
