Thanks guys!
I used a Canon 10D digital SLR camera with flash and a piezo-electric sound trigger. The exposition time was around 0,02 millisec, unfortunately not short enough to freeze the bullet. (Only a $5000 microflash can do that.) The shots were made in complete darkness - the range master was a bit uneasy about that, but we used extra safety measures.
The 1st gun is a FÉG ACK .45ACP pistol shooting FMJ.
The 2nd is a russian made MCM (or Margolin) .22LR pistol with high velocity ammo.
(It's cheap and beats the tar out of *any* target pistol under $1500 in terms of accuracy.)
The 3rd is a SW 640 in .38spec.
The ammo was some kind of Fiocchi JHP I think.
More (STI Edge, P7, P228 and so) coming soon...
