Source for lightened hammer spring for Uberti/Remington 1890

[Springfield Slim SASS #24733]

I haven't been able to find anyone who makes these for my 1890 pistols.

Probably because no one does since the 1890 is not terribly popular.  Your best bet is to buy a replacment spring and grind and polish it yourself.

The 1875 Remington revolvers are the same internally as the 1890s! That  VTI spring will work fine in your 1890.  You can make minor adjustments by carefully rearching the spring if needed.

 

I replaced the factory springs, (which had been ground and polished) with these in 2005!  They have worked well and not failed in nearly twenty years of hard use!

You can replace the stock spring in the 1875 Remington with a lightened Colt spring without much difficulty. The trick is to make a spacer that will fit into the spring notch of the frame.

 

I cut the spacer from a piece of scrap extruded aluminum I had lying around. Once cut to the same height and width as the notch in the grip frame. The spacer goes in the forward portion of the notch so that spring pressure is against the top of the spacer. Use a file and round over the top edge of the spacer that the spring will press against. 

 

The spring / spacer combo should not fit tightly into the notch but should have the same approximate fit as the original folded over spring.

 

Wish I had a picture as it would make this mod self explanatory but I no longer have those pistols.

Just ordered a couple. Mine look kinda like that, but it didn't seem to lighten them up enough.

It may be a little time consuming, but if you carefully rearch the mainspring a little at a time, you can get the best spring tension for your purposes.  This avoids grinding and polishing the spring which removes material and increases the likelihood of breakage.  It also allows you to put tension back into the spring if you’re not getting reliable primer strikes.

 

The springs in my “main match” Remingtons are over twenty-two years old and have fired a couple hundred thousand rounds in the twenty-two years I’ve used them!
