Buying a used Perazzi can be a n iffy proposition. Barrel and trigger mods abound. Older guns in particular have been around long enough to have attracted the attention of the dolts that thoughtlessly " fix them up". You would not believe some of the things that I've seen done to them. Having someone who is actually familiar with the guns evaluate a used one is close to a necessity.
Over the last forty years or so I've had a number of them. I still have several. I seldom shoot anything else.
Best of luck
