Well, Jason at Lipsey's has done it again.
They have a NEW Ruger .41 magnum,, Flat top,, ON THE MID FRAME,, as a distributor special! Both in 5-1/2" barrels,, blue & stainless.

But one feature I see is the fact that the blued version, (as well as the stainless version as always,) NOW has the easily replaced FRONT SIGHT blade!

This gun should sell quickly & quite well!
 
And, it's a Bisley model to boot! 😉👍

 
Verrrrrrry interesting!

Just checked the SAAMI specs for the .41 and .44 Magnums: both show 36000 psi average operating pressure.

So . . . same operating pressure as a .44 Magnum in a Mid-frame! Wow. Wondering what this will lead to. ;)
same pressure over a smaller area (less stress on the frame) also thicker cylinder walls

Same pressure over smaller area produces higher stress on the member, but increasing the cylinder wall thickness could protect the frame. Revolver failures usually start in the cylinder.

Chamber bore for .41 mag is smaller than same for .44 mag, so that results in thicker cylinder walls for the same outside diameter cylinder. The difference is very small, but I'm pretty sure the engineers have run the numbers. ;)

I am referring to the force applied to the top strap which I believe is the point of concern for the mid-frame guns. Rearward force applied to the gun by the cartridge face is less in the 41 mag compared to the 44 mag operating at the same pressure. Otherwise a 357 operating at the same pressure would cause the same concern.

Isn't that a function of recoil, which is essentially a function of bullet mass for a given velocity? The cylinder pressures in .357 and .41 and .44 mags are all at 36KSI and only bullet weighs vary. So cylinder pressure itself doesn't directly play here at the top strap. Not arguing here, just don't fully understand how the top strap load is generated and applied.

Up til now, the hottest chambering in the medium frame was .357 mag, which although it generates about the same cylinder pressures has a considerably smaller chamber bore and is not a problem for the cylinder. The .45 Colt's chamber bore is considerably bigger, but ii's only about a 15KSI round.

Just curious. :)

There have been midframes converted to 480 Ruger, and even 475 Linebaugh, which run 48k and 50K respectively. The frames are just as strong as the big guns. I have a Clements 500 S&W Special (1.275" case based on shortened 500 S&W Mag case) built on a 50th Anniversary 357.

As far as the factory midrame cylinders are concerned, blued are made from 4140 at 38 Rc. Brian Pearce converted and purposely blew up USFA guns in 44 mag just to see how strong they were. USFA cylinders are the same dimension, composition, and hardness as the Ruger mid frame. Several midframe 44 specials have been punched out to 44 mag with no ill effects, at SAAMI pressures. While I have no desire to turn any of my 44 specials into mags, I would not hesitate to do so, if I was so inclined. I am no expert. Just stating some facts, and opinions. Do your own research and draw own conclusions.
 
Even though the MSRP at about $900 isn't as high as I expected …… I'll still look to spend my $900 on 3 screw Flattops and 3 screw 41 Magnums.

But I gotta admit, the Bisley grip is a perfect addition.

In my case I'm good with .41's but if the stainless were a full size I'd have gone for it.

They're already showing up on gun broker:
