1 1/2" and 2" frame differences
 

What are the dimensional differences between 1 1/2" and 2" frames (12ga) and the barrels that would go with them?

Try looking in the FAQ's from the Home page.

Thank you. I should have stated my question better. My curiosity is more so around the length of the frame than the width, the length of the lug.

The length of the frames, both hammer gun and hammerless after 1882 are all the same.

It is also important to note that barrels of the different frame sizes are NOT in ANY way interchangeable.

Brian, I will differ with you on this point. I have a 1/2 frame gun with a set of #1 frame barrels that work very well. Thanks for your expertise.

Correct, forgot about that, the 1/2 frame barrels were able to be put on 1 frame guns. I too have once seen a 1/2 frame 12g that was born as a 1 frame 16.

Could a 2 barrel work on a 1 1/2 frame for a 12ga?

No.

Unless you wanted to dissemble and restrike the barrels, then reassemble.

If you have 1 1/2 frame barrels now, what is wrong with them?

Very pitted bores, but mostly I was just wondering, since 1 1/2" barrels seem hard to find, and the posts above give the idea that in certain situations different combinations will work.

Usually pitted bores are not as bad as they appear, do not present a significant danger and are inconsequential to patterning. They can often be honed if an owner is bothered by the appearance and with the understanding that Parker barrels can usually be honed and reduced in wall thickness by up to .010 before unease sets in. Knowing wall thickness is critical.

By the way, the frame number designations are not inch measurements. For example, a 1/2 frame 12 gauge is not 1/2" across and a Number 2 frame is not 2 " across the bolsters.

That is why i made the comment about frame sizes not being interchangeable, because i knew where this was leading.

Oh I thought it was an honest question. It wasn't ? Am I missing something?

I would be looking for a set of barrels of the frame size of my gun rather than trying to fit a different size of barrels.

No, i just figured the OP was looking to fit barrels from one frame size to another.

I asked a reasonable question, and prior accounts here about a 16ga frame size/barrel combination made it sound possible. My question was about a span of difference between a 1 1/2" and a 2", which does not seem like that much difference.

I am participating in this site to learn about a fine shotgun. My particular shotgun is not fine; it was wreck when I got it, and it may remain a wreck. I am simply striving to make what I can afford usable again.

I asked an honest question.
