I got mine when they first hit the shelf last year to do a comparison. It is indeed a Turkish Glock clone in all respects, however I think they failed on the finger grooves and the trigger shape. I think there was a reason Glock went away from the finger grooves but they also added that silly 'pointed' trigger on the G48 which I find to be annoying. I re-contoured the trigger face on the STR to a more traditional flatter face and it is stellar. Biggest downfall is the lack of suitable accessories(sights), however I think you will find a leather holster for a G20/21 or an M&P work fine(kydex G21 not suitable as lack of retention without modification on some models) and standard double stack mag pouches(non Glock) certainly do the trick.
Pics are readily avbl on the web if u need to see one
