With how many brands of ammo have you experienced this? Any of the "hotter" ones, like MiniMags?
Most of these little blowback pistols chambered in .22LR are very stiffly recoil-sprung; this is to protect the slide from the forces it absorbs during recoil. Because of the wide range of power levels in .22LR ammo, it has to be strong enough to "ride out" the hotter stuff. The downside of being strong enough for that stuff, like MiniMags and Stingers, is that the weaker "bulk" stuff, such as Winchester Super-X or Remington Golden Bullets, doesn't have the oomph to oversome that spring.
My FEG AP22, a very similar gun based on the same maker's PA-63, actually demands high-velocity fodder, and it's so inscribed on the magazine.
