Actually, most budget Arms guns aren't Polymer 1-shots. Only the Auto-3 really fits that description. The vast majority of Budget Arms guns are kind of misnamed. They;re usually at least ST and often times more expensive than others.
The C-13 is the best 5mm you can buy being ST reliability with 8-shots.
Meanwhile the Astra Style 6 and the Czar beretta are both UR, and have either fewer rounds or shorter range.
In the Light Pistol brackets, the POS (clever, right?) guns are the Astra Style 6, the Czar, the Browning 25, and the Dai Lung, all super cheap, all Unreliable.
The budget is one of the more expensive ones and as stated, is ST reliability
The budget Arms Laser-9 is not the best 9mm you can buy, but it isn't bad. ST reliability, built in laser sight, full auto-capable. It's much more accurate than other full-auto machine pistols, and can do a 3-round burst, which is uncommon. It's also not the cheapest. Honestly, if you need a full auto 9mm, the Laser-9 is about your best bet. But it's expensive, ironically. Only a Glock costs more in the 9mm machine pistol bracket.
In the Medium pistols category, the POS guns are the Fashion Gun 9 and the Teen Dreem (both posterboys for the POS), the Starrior 4, the Kang Tau, and towards the higher end of POS guns, the Dai Lung Streetmaster and LeRoi Maxi-10. Exceot the last two, all these guns are under 100EB, all are unreliable, and some of them explode or melt under heavy use.
Meanwhile the other medium Budget Arms gun is the C-41, which is +1 WA, VR, and costs about 600eb, so most definately NOT a POS.
On to heavies, the Espinoza One-Shot is literally a POS, the Dai Lung Magnum is the king of the heavy POS, and, alas, yes, the one and only POS from budget Arms, is the Auto-3...BUT of the POS guns in this category, the Auto-3 is the most expensive and LEAST likely to explode (10% on a fumble instead of 60%)
In Very heavy there's really only one, the .44 Automag.
So I'ma call BS on budget Arms being a POS brand. Only one single model could be classed as a POS, and even then it's the best possible POS. All the rest are either average or exceptional and none of them are cheap.
but yea, stay away from anything by Dai Lung
