I need some help here with the chokes in my Perazzi MX8. The barrels are stamped 18.4, and the gun came with Perazzi factory chokes in 0, 4, 6, 8. I'm looking to buy a pair of #1 factory chokes but when I measure the inside of my barrel (without tubes in) the diameter measures about 20.5 which corresponds to the outside diameter of the chokes. I'm lost as to what chokes I should buy 18.4, 18.7, ???? Can anyone help?? Thanks.

Show me your choke tubes, I can tell you what you have, we can go from there.

I'll take some pics tomorrow and hopefully figure out how to post them. I'm pretty sure they are third generation tubes; threads at the bottom, flush, and black. Thanks for the replies so far.

3rd. generation chokes. That's the only one I don't have, sorry.

I thought that all you need is the generation of the choke, then just ask for constriction 1 to 10. So if SteveW got the generation right, you would ask for two 3rd generation #1 chokes.

Now if you want exactly .004" constriction, you need to send the barrels to a choke maker that can make 3rd generation Perazzi chokes. The choke maker will measure each barrel and make the chokes according to each barrels actual diameter.

Washandwear, You must be new on here. Steve W knows more about P guns than anybody on this site, including Whiz. They are 3rd gen chokes.

Thanks to everyone for your replies. If I understand correctly, these are third generation chokes, and according to the research I've done, they only came in one bore size; is that correct?

Yes. Only 18.4 mm. If your bore gage reads differently, try another gage, the Italian proof house numbers are very accurate. Unless the barrel has been worked on.

Perazzi started to make big bore barrels years after they switch to 4th generation chokes.

The max. bore size allowed by the Italian proof house is 18.8 mm.

Rod, you'll have better lock finding #2 chokes.

I've taken measurements on the inside of the barrel with the chokes removed, and also on the outside of the choke tubes. I know the measurements seem whacky but the digital gauge I'm using appears to be accurate. I know something is not quite right because the stock factory choke tubes fit just fine.

Regarding Steve's recommendation to buy #2 tubes: I have a set of Briley ultralight tubes for my barrels and the reason I'm looking for #1 chokes is because the Brileys in 28 & 410 fit just a little loose at the muzzle with the #0 chokes. The 20 ga. tubes fit just fine. Just looking to tightening up the fit on the 28 & 410 a tad. I've measured the end of both of those gauges, compared the maesurements to the Perazzi factory inside diameter/constriction numbers, and I don't think they would fit in #2 chokes.

at least, now it makes some sense! .004 worth of choke wasn't worth the bother.
But then again, buying 40-80 dollars worth of c/t doesn't make sense either. Why don't you shim up the skinny ones with tape? Odd number Perazzi tubes are difficult to find, and I don't think you want to change c/ts every time you change gauges.

Sorry, I've been away from this post for a while. I have put a small amount of fingernail polish, yes...fingernail polish, on the tube supports and that seem to do the trick to stop the slight rattle. Kind of odd but it did the trick.

Rod, if finger nail polish worked, maybe Teflon tape will work better.

Before just getting Perazzi #1 chokes, you should talk to Briley to hear what they suggest. Especially if you bought the sub-gauge tubes from them.

If you do decide on new chokes, I think that you should have Briley make 2 custom chokes to precisely fit the bigger one of the tube sets or the one you use the most.
