There’s a letter code. Look on the bottom of the rec’r. I think that code is on the Beretta forum here.

Perazzi has 2 bbl diameters for factory chokes. .724 and . .736. Trigger groups come several ways flat springs . Vs. Coil springs and selector or no selector.

 

How did you determine you need a new trigger group? Date code is on the bottom flat of the barrel. Google Perazzi date codes. Those are excellent shotguns. Before you modify anything Irecommend you shoot it first.

Best for you would be to contact Don Rackley. Email: donrackley@gmail.com

 

I should’ve mentioned Don is a Perazzi gunsmith and sells perazzi parts. He has several video’s on YouTube.

 

Thanks guys. An individual that I know looked it over and felt the trigger group needs replaced. I'll have to ask him why he said that.
I have shot it and it is definitely butt heavy compared to my Guerini which is a little muzzle heavy and more balanced. I shoots fine with no issues. The full choke on the top barrel is taking some getting used to. I'm used to being able to barrel select so that's a little wierd.
I'll try to get some pics on here soon.

 

Here's the pics. Serial numbers match. It has Acciaio special on the barrel on the bottom.

 

1979 to 1980 gun

That’s an early type 4 gun. Meaning it has the self adjusting forearm iron.

Remember that all Perazzis start as an International trap gun. 2 shots per target. They added choke tubes to just the bottom bbl 1st and then top and bottom next. Selectors came later.

The gun at 45 years old looks okay.

 

Hey guys I'm looking at getting a #4 choke tube but I need to know the bore. From the photos I posted which number indicates the barrel bore? I searched online extensively and couldn't find the info
