New FX Side-Shot (Plastic magazine) fix for Slugs is here.

To be fair they did use the design of the original sideshot mags, which was popular. When they was designed slug shooting was not as common among most owners, and probably worked fine for most pellet shooters. Now that they do sell slug liners, the mags should be designed to work for that purpose also. What FX maybe could do is to redesign there own inserts similiar to the custom made ones, and offer them for free as a retrofit to customers which already has troubles with slugs or pellets. I do not see getting a new mag on waranty of similiar type will fix the issue, as it seems to be the design itself that is the cause. 
 
There also is a guy in europe making similiar inserts https://www.oh-snap.dk/vare/magfx/, which work great. I agree the original high capacity magazines for the impact is not good for slugs. They might work for long slugs (have not tested), but shorter medium weight ones will easy flip sideways. The reason is that the cups which feed the slugs are to narrow, and doeas not give enough support on the side on the pellet/slug. They are probably designed that way, to give room for more shots. With custom made inserts, the cups are spaced further apart, and encase the pellet/slug all the way to the side, holding them in place while feeding. Loosing some shots is well worth the benefit of having precise feeding.

In my opinion FX should redesign the mags in a similiar way, so they work better for both pellets and slugs.

Specially on the .25 cal they went greedy and added too many shots there, 28 shots don’t fit well, when I tried, the circle for the pellet overlaps with the next circle and that reduce the size of all circles, even 27 was not perfect, with my insert in 25 you will have 26 shots but should work perfect, and if not working perfect just contact me and I’ll take care, I’m not perfect and errors can happen but I’ll always be there to make it right. 

My first troubles did arrive when I was trying the H&N grizzlys in .25, where some did flip sideways and totaly jammed the mag. But I did noiced there sometimes was some hickups with pellets also, before that in my .22 cal. After I bought the inserts to my .25, I was so happy with the results, that I ordered a couple inserts for my .22 mags also. I have not shot much slugs in my .22 barrel, but did load up the mag with the 21 grain H@N slugs which are quiet short, and shaked it a little, and turned it upside down. Some would flip, and 2 of them actually ended up wrong direction facing tail first. Good we have people like you who offers a fix:)
