Air Arms S510 xs .25 after market mags

Is there currently anyone making a 3d printed mag for the newer .25 AA S510 XS.. I know there used to be someone but can not find any currently being made.. my newly purchased used S510 .25 has eaten 2 breech o rings in approx 200-300 pellets and each time has been when gun has been tilted vertically working side lever, have read this is a known problem from at least 2019 and AA is supposed to be working on it. Have they fixed this issue with a new mag I'm not aware of. thanks for any info.
I'm now trying to remember to hold gun horizontally when cocking, hard to do when all other of your pcps do not have this issue..
