I've got a shotgun with from the 40s with a Poly Choke on it and have a question. Mine is the one with the ported end on it, I understand there were two versions, one with the porting and one without. Am I OK to cut off the ported part and leave just the knurled end, in my mind that would work and reduce the ugly factor a bit.
It's going to be my bush and upland gun, I'm looking forward to patterning the choke and having instant adjustment on the fly.
I've pretty handy with the hacksaw and file so no worries there.
Here's a pic-

I think it looks better with the muzzle break portion. Poly Chokes are very handy and the looks do grow on you. If you were to every sell the gun and give it away, the next owner would appriciate it not being cut. I don't think cutting it will effect the performance of the Choke. I have a couple and never modified or removed them because they are one of those items which appear to be tightly regulated when importing them from the US.
 
Appreciate the reply, think I'm going to go ahead and cut off the ported part. The value of a near 70 year old shotgun that already has a poly choke on it is not likely to change with what I'm planning to do.
It's not the first Poly Choke gun I've had, I just don't think the porting is necessary, from what I understand it does make it louder which is not desirable in any way.
Might cut the stock as well, check out this video:

The added bulk of the port end is appreciated for your swing not to mention it gives something to grip when adjusting the choke on a cold day. I have cut off two ventilated sections form Poly Chokes and I ended up regretting it. But it is yours to do with as you wish.

I had one of these poly chokes put on many years ago. There were two versions, plain and the deluxe one like you have, and what I had put on. I did not like the looks of it either so I did what your going to do and cut her off with a hacksaw and cleaned up the end and blued it. Mine however was never installed true to the bore and it shot 8" to the R and 24" low at 40 yds. So the hacksaw came out again and I cut the barrel off at 18" sweated on a set of rifle sights and it became a slug barrel. I then bought a new 28" modified barrel for the gun which I eventually had thin wall screw in chokes installed in.

My best advice to you is to first off pattern the gun to verify it's point of aim or impact at 40 yds. Then pattern with different loads and shot sizes to see how it throwing the pattern. If all is well saw off the ugly part as planed and carry on. If the results of the pattern board are not good and you are really in love with this shotgun I would have screw in chokes installed if the barrel thickness is there.

This is the condensed version of my experience, I did a lot of pattern board work with mine after we tried some barrel bending to correct the POI issue. Bending the barrel was to tricky and the poly choke itself gave poor patterns. So off it came. These poly chokes had a love hate relation ship. Fellas either loved them or hated them.

The end of it is designed as a compensator and disperses excess gas to give better patterns... much like the old Cutts Compensator... not so important with the modern plastic wadded shells...
 
Thanks for all the replies, I'll try and get it out to pattern on the weekend and see where it shoots. Having never used one with a ventilator, wouldn't there be a chance of the wadding(or bits of it) getting stuck in there?
 
Some folks like Poly Chokes, I was not one of them. . Fixed that problem by purchasing another barrel and cutting the Poly Choke off with a hack saw. . Worked good for me as I had a F/C barrel and a cyl, barrel. .
