Hapo - a few thoughts for you:
- Have you tried to adjust the trigger? The details are available (PM and i can help). It also helps to remove the side cover so you can see what your adjustments are doing. You can't do much with it in terms of stages but you can adjust weight, travel, etc.
- It's Russian design, I believe their premise is aesthetics come second to function. So complaints about a finish blemish will fall on deaf ears.
- As far as your magazine issue, did you get the adjustment tool and guide for the magazine? I had a similar issue with one magazine and simply turning in the center about 1/8 turn fixed it. You said all they did was send you a new magazine - so I'd take a look at the adjustments if you haven't already.
- As far as color goes that sounds kinda yuck, but if it's all that's available (and even Krale seems pretty out of stock across the board too) it's just a color.
- If you plan on ditching the safety (not recommended) you might as well adjust the sear to go off with a minimal pull.
