    Two Questions on Perazzi Choke Tubes;

    (1) Is there a chart (somewhere on the web OR can be pasted in this thread) which shows which # choke relates to what label - for example #3 = Modified/#10 = Extra Full.

    (2) I have heard that odd number chokes are only for single barrels and even number chokes are only for O/U barrels... is this true? Is there a problem if they are interchanged (i.e., can I use an odd number choke in an O/U and an even number choke in single barrel)?

    Perazzi choke constrictions are in 1/10th of mm. (like the rest of the world, but we don't care)

    Easiest way is to multiply the number by 4, then you have them in 1000th inches.

    Example: #2 x4 = 0.008", #4 x4 =0.016". then you decide 0.035" or 0.040" is Full.

    Perazzi has a chart in the back of their catalogue.

    thanks for the forumla... unfortunately I do not have a Perazzi catalog... is that chart somewhere on the web?

    also - does anybody know the odd vs. even issue?

    The odd # & even # chokes are just different constrictions, because the differences are so small, so factory don't ship them together. You can use them together.

    However,

    There're 4 generation chokes they are all interchangeable within generations.

    The 4th generation chokes come in different bore sizes, they are still interchangeable after you calculate the differences.

    thanks again...

    A follow-on question;

    I understand that different generation chokes have their threads at either the top (muzzle-end) of choke tube or bottom (stock-end) of the choke tube. Can you tell me which is which.

    Only the first generation choke has threads on the top.

    Second generation look the same as first, but threads on bottom. Both have 1/4" extension.

    Third is flush, in black, original forth is flush in silver.

    Forth generation has either flush, extended, and big bore.

    Are 2nd generation Perazzi chokes available for purchase somewhere?

    The Briley & Wright's chokes seem to extend longer than actual Perazzi chokes do - and I would like keep it original looking.

    Be careful with the information on Briley's site,

    What they described as 2nd. generation choke is Incorrect! Only 1st generation chokes are threaded on the top.

    Second generation chokes are available, first generation is more difficult. If you are referring to what Briley' s site said, you're looking for first generation.

    Let me know what you need, PM me. I'll check in the after noon.

    For the record, 1st generation on the left side, 2nd. on the right.

    The reason Briley refers to them as 2nd generation is there are chokes that pre-date the early TMs (comp V) and MT-6. They are top thread also, but shorter. From Ennio Matterelli's MX-8 late 1960's to 1974 45,X00. Rare, but Briley knows chokes and knows Perazzi's.

    Sam..... Are your choke tubes threaded at the top or the bottom? If they are threaded at the bottom, Briley has the answer to your problem. Call Briley and ask for Stormy. I have an MX3 Special that has the generation 2 tubes in it. I didn't like the way the gun looked with the stock tubes in it so I called Briley. They are, as I write this, making a set of 2 flush choke tubes for me for this gun. They will run you $65.00 per choke. I don't know if they can make the generation 1 tubes flush fit or not. A quick call to them will answer that question..... Dan Thome (Trap2)

    Trap2 -

    I tried calling Stormy (via Briley) but he is out today - I will try him tomorrow.

    The threads are at the bottom of the tube (the stock-end when inserted)... what do you mean when you say "flush"? I am seeking generation 2 tubes which extend out the barrel the same length as the factory generation 2 tubes do - approx. 1/4". Is that what you mean?

    Sam.... No, the tubes I now have stick out about 1/4" from the end of the barrel. I wanted tubes that are flush with the end of the barrel and has nothing beyond that. I just think it makes the gun look much "cleaner" that way. I also don't care for the way the factory chokes pattern and am not satisfied with them... Dan

    Hello Sam we have some 2nd generation choke tube.
    The cost is $ 31,00 USD plus shipping

    PS just for the record there is a difference in tread size between the new and old generation chokes:
    old 20,5 x 0,75
    new type 21 x 0,75

    Gapper is correct on the pre-type 1 tubes. I have a Mirage pigeon gun with choke tubes like that in the bottom bbl. It's a 73 or 74. Easy to identify as the knurling on the external section is not as fine as the type1 and later.
