1873 Lever Action .44 Magnum

Registered Users do not see the above ad.

In the "What will they think of next?" category:

After years of warnings about the weak action of the 1873 toggle link lever action, Uberti now offers the 1873 in .44 Magnum.

Darn, but that 20" case hardened version is one gorgeous piece of walnut and steel!

What did they change on the 1873 "toggle link" action that would allow it to handle .44 Mag pressures? (Or are you suppose to reduce your loads, like you have to do with the .357 Mag models?) According to most "sources", these guns would come apart at anything much over 18,000PSI.

It must be the modern steels, still gives one a bit of a start. The case hardened, half round barrel version is nice, what will they sell for in the “real world?”

I'd say they are using a pretty darn good grade of steel in the locking mechanism! It would be interesting to take one apart and compare to an original.

Mike, I am thinking the same thing. I looked at a cutaway of the 1873 when I saw the similar thread on the Leverguns forum. I don’t see how they could change the mechanical advantage of the toggle link to withstand higher pressure. My only other thought is a better steel and less flex in the link.

Many of the original 73's had iron receivers and the steel back then wasn't as good, although they were wizards with case hardening. I remember reading about the testing done on the toggle link '76 winchester when it was released, which eventually involved over 100gns of black powder and about six bullets in the barrel if I remember right to blow the gun up, and even then only one toggle gave way. It wasn't a catastrophic explosion.

I realize smokeless is a different beast to black where pressures are concerned but with modern steels they might be alright. I have a ,357 magnum '73 and I don't run full power loads through it, because I don't need to, but I feel the rifle would handle it if need be.

I would be perfectly happy with one in .357 magnum! Straight stock, octagon barrel, and case hardened please!

Here is an excellent cutaway diagram of how the Winchester '73 action works:

Ive been looking at this rifle too. According to what I can find on the net the steel has been upgraded. Thats why it only shows blue receiver for now. Seems no one has one yet. Concerning the test on the M1876, they ended up with six 480 gr bullets and 203 grs black in the 45-75 before the barrel blew. Action was damaged but still held. There were some early imports of the 1873 replicas made in 44 mag. The Uberti 44 mag will take the 1873 to a whole new level.
