A LEO trade in from Britain? As in some UK police force used it? I would check that out thoroughly, I would be surprised if anyone in the UK is using anything other than a Hi-Power or Glock. They aren't super friendly to or current on handgun technology and models.
After that hurdle, based on US military tests of the M9 (essentially the same pistol), by the time the barrel and slide wear, the frame is probably ready to crack also.
Assuming you're in the US, CDNN is selling the AT-92 from American Tactical Imports, which is a Turkish Yavuz 16, which is an essentially perfect identical clone of the early-1990's Beretta 92. I have one, quality is great, apart from markings you couldn't tell it from a Beretta. That would be brand new for about the same price - they are $299 at CDNN.
