I picked up this circa 2001 manufacture Uberti 1873 .45LC in a trade deal for an original 1873 that was collectible, but with a poor bore and that needed a little action work. Although cosmetically fine, when I got it, it didn't feed anything except RNFP ammo, the action was "stock" and pretty "clackety-clack" and someone had (VERY poorly) drilled and tapped the tang off-center for a Lyman peep.

My ultimate goal for this rifle is CAS use, so the tang site was totally useless to me. (I still have it in a box). The tapping was so poor that a plug screw looked awful, so first step was to have Gunco in Ottawa plug the hole with a TIG weld and dress the tang back down as close to possible to "stock". To hide the repair, it was carefully rust-blued in that area then aged - it more or less blends in with the color case hardening now. Certainly good enough, even if a corned of the roll stamp is missing.

Next the super-ultr-heavy Uberti lever safety spring had to GO. I installed a Longhunter ultra-light safety coil spring in lieu of the stock leaf spring. So that the trigger spring screw would not protrude, I ground the arm off the stock lever spring and re-installed it over the trigger spring as a spacer. You'll also notice the hammer spring has been ground thinner and a slit milled down the middle of it to reduce the power.

As part of the fix for not feeding semi-wads, wads, and cones, The barrel was removed from the action and the bottom 1/3 of the chamber mouth was slightly throated and the entire chamber mouth de-burred. I also made a lot of changes to the action mechanism and feed block (more on that later), but it now feeds every bullet I could throw at it flawlessly.

Front sight was replaced with a Pioneer Gun Works speed dot.

Next to lighten lever resistance and speed up the action, the stock brass cartridge carrier went into my milling machine for a crash diet. Some people like going to the aluminum blocks that are anodized a brass-ish colour, but I'm not a fan of those as you wear away the anodizing fairly quick and they start looking ugly. This "lightening" solution is not quite as light, but it's more durable and will last as long as the gun. A few smiths have their own way of milling lightening cuts into the carrier blocks, but this is how I do it - so far I haven't seen anyone else do it exactly like this (which could be good or bad - lol!)

Other mods I haven't photographed yet:
-PGW short-stroke kit has been fitted and timed (for those who care, these kits are MUCH harder to install in a .45 than a .357 rifle - you have to remove a LOT more material from the lifter to get the action to time. If I was doing these for customers, I'd charge more for a .45)
-the gross OEM plasticky finish has been removed from the wood
-stock set re-finished with a light treatment of walnut color oil-based leather dye (to make the euro walnut look like black walnut) and 6 coats of Lee Valley polymerized linseed oil mixed with bee's wax
-Leather finger-guard added to the lever, baseball stitched with waxed sinew
-Whisper springs added and tuned
-action internals de-burred and slicked
-Firing pin extension replaced with hollow extension and fitted to the bolt
-firing pin tip re-contoured and debarred
-all (soft) OEM action screws replaced with VTI hardened screws

I'll post more pics later, but some of the new action internals are off at a local shop to be hot caustic blued.
 
Yes, I actually have - though it's not common from what I understand (I've only done one 44-40, an early Navy Arms marked Uberti). It's totally doable, but usually 44-40 guns don't need any help to feed due to the cartridge bottle neck and also 44-40 is also not a popular CAS calibre compared to 38SPL or 45Colt. Generally you just lighten the action or short stroke the action to the user's tastes. The biggest issue with tuning any 1873 for CAS type shooting is the cost of the custom parts - if you want the whole 9 yards, it can get spendy. Short-stroking a 44-40 is as much work as doing a 45 as the cartridge rims are similar in diameter.

To put things in perspective, I don't do a lot of these rifles. This is, I think the 4th or 5th 73 I've tuned for racing, and I did a 66 once as well. That is enough though to know the tricks and potential pitfalls ;) Most of the learning is on the 1st rifle - lol. I'm not a commercial gunsmith, I'm an Engineer and a machinst who does the odd gunsmithing job. Most of the work I do is not hard, but would be made so if you don;t have access to things like welders, milling machines and lathes.

When I say it takes longer due to the extra material you have to remove, I'm not referring to the extra filing time, but rather that you have to totally disassemble the action, file a few thou off the lifter ledge, re-assemble and test. On a 38, I usually have to detail strip the action about 4 times to get it right. On a 45, it's usually more like 8 or 10 times.

Still though, I prefer starting with a basic 73 and adding the parts I prefer to, say, buying a Taylors Commanchero for $2200+ and being stuck with whatever parts Taylor's Inc. preferred to use to improve the stock Uberti 73's they buy, probably because they got smokin' deals on whatever brand X short stroke link kits. I don't mean to crap on the Comanchero - it's a very nice gun for what you pay, but I'm picky about what exactly I want my guns to be. Most of the "commercial custom" or "deluxe" guns offered by the big suppliers are also pistol-grip versions, which I personally don't like despite it being considered a more desirable feature.

I tried to load SWC for my '73 44-40 and was not able to get them to load. Maybe just operator error:confused:

Post some pics of the whole rifle, always like seeing these rifles:D
 
It's possible that your throat could be burred or the loads you are using were not roll-crimped. Either way, it could likely be made to feed a lot better by having your local smith spin the barrel off and carefully debur the lower 1/3 of the chamber mouth and polish it slightly. You don't want him to lathe cut a bevel in the full chamber circumference as none of the typical 73 winchester pistol rounds has a bit cartridge lip and if the round goes too far into the chamber you may worsen headspace or get light primer strikes.

As for pics, these will have to do. I can't assemble it b/c some of the parts are out getting blued - the links and lifter arm.

And here is the stitching on the lever wrap - I seem to actually be improving at doing these - lol. If you add one, I would suggest rubbing real beeswax all over the metal you will cover before applying the wrap to ensure the lever doesn't rust if the leather gets damp.

I was thinking of polishing the elevator on mine to reduce friction is this a good idea or would it be best to maybe do a cross hatch patern to give oil a place to stick or just leave it stock.
 
On most of these guns there is at least 10 thou clearance all the way around the elevator. I would just oil it the way it is - there's not much resistance to reduce. Some guys polish the sides, but most I have seen are already reasonably smooth. If you take off much more material, it will move side to side and may not feed as well.
 
Hooray! My parts got back from blueing at Gunco. Apart form a small section of the lifter arm, nobody ever sees these parts, but blued steel is less likely to rust than white steel, so I feel blueing them is worthwhile.

It's important when you put the guns back together to use a decent grease (not oil) on the spring contact points inside the action. I use wheel bearing grease here since it stays put and the location is not heat sensitive.

Here you can see the only visible part of the lifter arm, alongside the portion of the lever where it's hinged in the receiver, and the surface just forward of it. The blued part looks oh so much better than a white part as they are shipped to you. Also, the surface you see just ahead of the lever hinge is the ledge you file (and later polish) to adjust the carrier timing.

And re-assembled:

Gun is now working AWESOME. Unlike 90% of these out of the box, this 45 Colt now will even feed un-crimped semi-wad cutters and flying ashtrays. The lever only strokes to about parallel with the bore, MUCH closer to the original Winchester design (actually a wee bit shorter), and the action is slick as snot. So much so it almost feels like a worn out action, except everything is actually very tight - just well polished with better springs and parts.

Hopefully this little writeup helps someone else tune and improve their 1873.
 
The one pictured is the PGW standard short stroke. The Super Short Stroke shortens it a little more, but does not operate as smoothly (more resistance). Like anything, there is a tradeoff to how short a lever throw you want. I prefer the standard kit myself.
 
Here's a little tip for everyone if you absolutely can not remove you're side plate screw and you really want to remove it, the take the but stock off and remove the mainspring assembly. Now comes the scary part grab your favorite hacksaw blade and you see that little screw that goes all the way across that's your side plate screw now cut it. It will take time but once you cut all the way through you will be able to remove the screw by hand. Don't forget to have a new screw on hand to replace it. Pioneer gun works has good screws and ships to Canada.
 
Fair point. The OEM screws are in there GANGBUSTERS and the steel is soft. I've always gotten them out, but I grind hollow ground screwdriver tips to precisely fit the screw heads and I wrap the handle in a thin piece of sheet rubber to get additional leverage. Ill fitting screwdrivers + Uberti = destroyed screws.
