Hehe, know the feeling.
It's the same for me, but regarding my TM Glock. All because I can't find a holster that fits a 6 seconds mount.
But anyway, the AAP turns from okay to good with just a hop rubber swap, when you consider the cost of the pistol (sub €100) and rubber (say €15 including a spacer like a ML I-Key) it's a pretty good deal! Treat it carefully and it'll last a while. Then if you want maximum performance/reliability/cosmetics you will naturally spend a small fortune on it, but it's the same with Capas, Glocks and pretty much all Airsoft guns bar MTWs and Mk23s, but those are the exception because cost/design/technology.
My pistol costs a lot, but I could have done without a fancy mamba upper, a CowCow hammer set, a TTI trigger, magwell and a dot, my carbine could have done without the expensive TTI carbine kit, charging handle+external selector, you get the idea.
It does feel toyish, I'll give you that, but if you want "realism" then the AAP isn't for you
