“SliXpring-Main” replacement Mainspring system is designed to complement an already properly tuned and short stroked Winchester style 1873 rifle or carbine. Its sole purpose is to provide a faster lock time (faster, more positive hammer travel), a more dependable primer strike and a more durable, longer lasting, smoother cycling competition grade spring operation. It, in most cases, will feel a bit more brisk in the initial cocking action of your rifle, but be assured it will respond much more smoothly throughout the hammer cycle than a normal leaf style spring, plus it is at least 30% faster than your competitively adjusted leaf spring. The “SliXpring-Main” kit requires competent installation with minimal stock fitting and is completely reversible to your existing arrangement.

Because there are so many different tolerances and dimensions between bolts, hammers, lower tangs, action frames and tune-up styles the “Kit” itself is manufactured so the qualified installer/tuner can fairly easily fit and align the unit for optimum operation. It will not fit the earlier square bridge lower tangs and some Border Rifle tangs without Tang modification. Also, since there are many different styles of shooting and needs for different levels of speed, the kit will include two axles. The basic axle will provide the fastest possible lock time and the most positive primer detonation while still retaining a smooth action cycle. A smaller diameter axle is also included which will still provide a noticeably faster lock time but with a slightly lighter, smoother lever cycle feel for the not yet absolutely competitive shooter.

The manufacturers want to clearly point out that if you have little or no idea how this Spring kit is supposed to work, get help or find someone who does know how to install them. Due to all the variations in machining tolerances on the different rifles this is not a “one-size-fits-all” perfect” drop-in set. It may/will take some individual fitting. Contact your local “Smith” to arrange installation. Our practice installations have taken about an hour to finish.

Replaces the stock firing pin with the newly designed and alloyed firing pin and spring. The design incorporates an engineered radiused shoulder that all but eliminates those broken pins. The alloy is MIL-SPEC the same as the M-16 and aftermarket AR-15. Minor fitting may be required. The pins are designed a little long so they can be fitted properly to each individual rifle. Complete instructions included along with a new firing pin spring.

This spring will work in rifles of any caliber, and in barrel lengths of 24" or shorter. Will not rust the way your stock magazine spring does. In barrel lengths shorter than 24 inch, the spring is inserted in magazine and cut 3 inches long outside of tube for proper tension.

These new stainless followers will not rust in the tube like stock followers.
For .357/.38 Special and smaller calibers.

These new stainless followers will not rust in the tube like stock followers.
For 38/40 and larger caliber.

We offer two different short stroke kits from Pioneer Gun Works for your M1866 or M1873 Winchester. Complete instructions included with every kit.

• The standard kit will shorten the lever travel of your rifle by about 1 3/4" - 2".
• The super short stroke kit was designed to be the shortest SASS legal short stroke kit you can buy. It's slightly longer than the SASS minimum to make sure your rifle is SASS legal.

Machined from 6061-T651 aircraft quality aluminum and hard anodized for toughness and long life. Weighing only 1.0 ounce, it is about 1/4 the weight of the stock Uberti brass carrier. Designed with all the clearance you need for installation with either short stroke kit.
Select Small Carrier - for .357/.38 Special
Select Large Carrier - for 38/40 and larger caliber

This spring replaces the flat safety spring for the disconnect (trigger block). The reduced tension allows the trigger to function as designed but gets rid of the annoying down pressure on the lever. Without the disconnect installed, the rifle can fire before the links are fully extended. Stay safe and leave the disconnect in the rifle.This is the same spring we use in all our 1873 action work. Easy installation.

The coil mainspring conversion kit replaces the stiff flat mainspring that comes in Uberti made rifles. The forward strut mounts to the hammer by riding on two ball bearings that are free to roll up and down the inner curve on the back of the hammer. This movement adjusts the leverage on the hammer, resulting in a constant tension on the hammer, from its full forward position to its fully cocked position. It will significantly reduce the effort required to work the action. Installation instructions are included.
The Model 66 kits are the same as the 73 kits - The difference is in the installation instructions.

Made from steel, hollowed out, and plugged in the front end. These weigh 40% less than the stock Uberti extensions, which allows reliable firing, even with lightened hammer springs. Will work in Uberti made Model 1873 rifles manufactured after January 2008.

This firing pin extension is made from steel, drilled from the front end to make it hollow, then plugged .
