20 gauge pump

Guntech can you explain this a bit more for me . When you say a Remington 870 20 gauge Lightweight is built on a true 20 gauge frame does that mean some 20 gauges are built on 12 gauge frames ?
Adding 20ga bbls to a 12ga frame is a very common practice esp for entry level guns. Not only pumps but this is done on SxSs, O/U and semis. Heavy shotguns are no fun for beating the feet upland use.
 
The Remington 870 20 gauge Lightweight is built on a true 20 gauge frame. I had one and it was a beauty.

I also like Mossberg 500s and my favorites (these days) are the older Lakefield/Mossberg pumps. They feel right. I've never owned a 20ga Wingmaster LW but have always wanted to. Had a large frame I should have kept-that gun seemed to find grouse for me.
 
A Wingmaster 20g with 26” is near perfect and you won’t find a nicer gun these days. The problem is finding them now.
I have just sent one in the factory box with maybe 3 boxes of shells thru it to precision optics to consign also have a 1969 and 1977 in the 20 gauge magnum These are great guns but I was afraid to scratch this one as it was so nice .
 
Remington hasn't made a 20 gauge on a 12 gauge frame in decades and they aren't that common. I owned a 20 gauge 870 Skeet in the heavier frame as well as a Wingmaster on the smaller frame in 20 gauge and the lighter frame made a significant improvement in handling.

You can tell a 20 gauge 870 built on the larger frame by looking at the barrel where it meets the receiver. The barrel has a slight taper on the large frame which is not present on the lightweight frame.

Your right My wingmaster magnum 1969 and 1977 model are both large frame the 2017 is for sure the small frame and barrels are different.

For sure, but they pop-up in the EE several times a year and not all listings point-out the difference. I bought my LF in a store and couldn't believe how good the condition was for the price. It was only when I was checking out they said "oh btw, might be hard to find spare barrels for this gun" We paused/I got an education.

I think I've held and LW only once-loved it.
 
Browning BPS Upland Special. 24" barrel.

They are discontinued, built on a 20 ga. frame. I bought a used one a couple years ago and will not sell it.

Top is 12 gauge BPS - 3" chamber; Invector choke - 22" barrel - serial number suggests made in 1988.
Center is 20 gauge BPS - 3" chamber; fixed **- choke (probably Improved Cylinder) - 26" barrel - serial number suggests made in 1985.
Bottom is 28 gauge BPS - 2 3/4" chamber; Invector choke - 28" barrel - serial number suggests made in 2020.
 
Some years ago, I had a Stoeger (?) SXS set that had 28 gauge and 20 gauge barrels. I currently have a "spare" barrel for my Winchester Model 12, but I have never fitted or installed it. I have sawed off a few barrels to shorten them from new - that usually required a new front sight or bead to be installed - but other than those mentioned, I do not recall any that were here that had more than one barrel. Even chokes - I understand some people think that interchangeable choke systems are a good thing, but I have never carried alternates with me - what is in the gun, is what it gets fired with - although I suspect some target shooting or clay games might have me swapping chokes, on the go. For OP's information, the BPS's that I have and have had, had the raised vent rib - perhaps 1/8" or so higher than the top the receiver, and removing the tube magazine cap allows the barrel to be removed - so I imagine "swapping" out a barrel would be pretty start-forward. My 12 gauge BPS has a sling swivel stud into that front magazine cap - I use a Butler Creek "mountain sling" with that one.

Most shotgun barrels that I sawed off ended up with no constriction - "Cylinder" choke (?).

That 20 gauge BPS that is here - 26" barrel - fixed choke - stamped **-, so probably Improved Cylinder choke:

A quick measurement with vernier calliper suggests that vent rib is slightly less than 0.2" (5 mm) above the receiver and slightly more than 0.3" (8 mm) wide.

Probably a silly (slightly off topic) question... But does anyone (other than the sporting clays/trap/skeet crowd) actually swap barrels?

Over the years I bought (and sold) a few guns that I had bought different barrels for... But it was more for the curiosity of it.
I swap barrels on guns quite often. A303 beretta 2.75" chamber for skeet then to a 3" chambered barrel for hunting
Remington 1100 I have several barrels
Mossberg 535 slug barrel for 28" smoothbore
I even swap barrel sets on a vintage sxs Damascus set with short chambers to fluid steel set with 2.75" depending what I'm hunting or what shells I have more of on hand
 
Pic of the 20g LW 870 DU that has never been fired. The 1100 below it has 2 barrels one skeet and the other mod screw in choke but it was before Remchoke so is an odd ball .Was not willing to send it in to be copied for fear of ending up with nothing so opted for the skeet barrel.

Another question . Any of you fellas shoot a compact or youth model of 20 gauge and how does it fit you ?
I know it’s all about how it fits the shooter .
I’m average height 5’10”
I'm 5'10" give or take 1/2" either way. A compact stock is really low in the comb for me and the stock places my thumb right up close to my nose.
Most compact stocks are not designed well and fit almost no one. Every lady or small stature shooter that comes out to skeet with one ends up getting their cheek slapped. Raising the comb height often helped the shooters. Some used beretta gel tec stick on pads while others taped foam to the comb

I can still hit what I'm trying to with them but it's not comfortable and I'm no near near as fast on point

Picked up a 20 gauge “ youth” model Tristar Viper 2 for the wife. Although shootable with the youth stock it was definitely not ideal, however it was literally the only model of the particular gun she wanted that I could find in Canada. We immediately reached out to Tristar for the full sized stock and it is miles better now.
I picked up a 20 gauge BPS pump a while back, my first 20 gauge and I am really liking it, fantastic little shotgun 👌

Edgy . Does that BPS have switchable barrels and is it wood or synthetic stocked ?
Thank You
