so i recently purchased a used kwa usp (original gas system i think) and found that it has some problems.
1. when the slide is locked back and you insert the mag and hit the catch release the slide goes a little bit and gets stuck from friction. but if you do the same and hold the gun's hammer back with your thumb so that the hammer doesn't touch the slide, the slide will shoot forward freely.
2. sometimes during operation, the slide will ALMOST return all the way, but does not make it the last 0.5cm or so. this happened twice out of all the shots from about 5 mags today at the game i was at. it's not too big of a deal, it's just a hastle to have to slap the slide forward (the last bit, it has to click into place, you can't just gently push the slide forward).
these problems happen on and off. it's weird. some mags, non of these problems occur... but some mags one or both problems occur.
any help would be appreciated.
