Here you go Attila
https://www.airgunnation.com/topic/25-fx-sideshot-mag-with-slugs-fix-2/ I've since used JB weld and its better than the construction glue I first used. Just make sure there's none (residue or anything) below where the center disk rotates. Adding an extra turn or half a turn on the tension helps too, and I put some superlube under where it rotates also.
Working *better than new, glad its still working great for you Kevin!
I see, you folks talking about old style smaller mags. I got the PP and the large mags, FX must have changed things in time between. bcs I never had any issues with the last pellet some were mentioning, also I just needed to bookmark the info for later (case of emergency). Not shooting slugs yet, no open shooting ranges here, and I still have about 10-12 full tins of JSB heavies to go.
