I’m just going to say it: 4.2-inch revolver barrels are an affront to proper gun etiquette.

Four inches. That’s the civilized standard. Four. A nice, sensible, aesthetically correct number handed down through generations of wheelgun ownership.

But then somebody decided revolvers needed 4.2-inch barrels to accommodate Canada.

Canada.

A country whose existence remains, at best, an unverified rumor. A people supposedly living somewhere beyond the northern border, apparently communicating in kilometers and demanding an additional 0.2 inches of barrel before they'll allow a revolver into their make-believe realm.

And here’s the crowning absurdity: after American gunmakers went to the trouble of appeasing this tiny northern market, Canada went and imposed a national freeze on handgun sales, purchases, and transfers anyway.

So what exactly did we accomplish here?

We desecrated the sacred proportions of the American revolver for a market that subsequently decided it basically didn’t want a handgun market.

That isn’t product development.

That is heresy.

It is false hubris of the highest order: believing you can improve upon the divinely ordained four-inch revolver by adding 0.2 inches of Canadian regulatory compliance.

My original Ruger GP100: 4 inches.

My S&W Model 686-3: 4 inches.

My Colt King Cobra: 4 inches.

These revolvers came from an era when manufacturers understood geometry, tradition, and the fundamental moral distinction between 4.0 and 4.2.

Then Ruger bent the knee to Big Canada. And soon Colt and S&W followed.

And for what?

This entire episode violates the most basic principle of America First principles in revolver manufacturing: American revolvers should be designed around what Americans want, not around the regulatory peculiarities of an alleged country whose principal exports are maple syrup, Celine Dion, and increasingly elaborate explanations for why you cannot buy the handgun we redesigned specifically so you could buy it.

So no, I will not normalize the 4.2-inch barrel.

Every one of them is a tiny stainless-steel monument to international appeasement.

Reject decimal-barrel globalism.

Reject Canadian regulatory imperialism.

Return to four inches.

America First.

And until somebody produces convincing evidence that Canada actually exists as a real country and not some cast-off neo-colony of the People's Republic of China, it doesn’t get a vote on proper revolver proportions.

Kinda old news...
Thar 4.2" rule has been in place for decades.

Not that it matters now...

Most weapon design is based on regulatory guidance.

Hmmm.....02"...

Apparently my eyes aren't calibrated enough to see that.

I get it though, imagine my consternation when I realized my 610-3 was 3⅞" instead of the advertised 4"

It's in issue with holsters. And again, Canada isn't a real place.

Canada turned perfect 4" guns into 4.2" guns.

I think the best part of this thread is the picture.  That Colt really does it for me.

I had no clue 4.2” was to appease the bagged-milk nerds.
You see that head come apart?

And 3" is best length for a K framed sized gun, and I don't own one.    I can't afford a Model 65 Lady Smith, which is what I really want.

The one I did had serial numbers on both the butt and the frame inside the yoke. Is not an ATF issue as long as you don’t remove both.
