Miroku 1873 comp model lighter springs

[Briscoe Darling # 69296]

I did a search looking for lighter springs for one of  my 1873 Miroku  competition models 
 

I did not see any results from previous threads

 

does anyone have a resource they could share?

Parts for the Miroku made Winchesters are not available here.   Boulder Canyon Bob found a German company that sells Miroku parts, but with the exception of the main spring, lever safety spring and bolt extension it doesn't show any other springs.  On the web at theduke.de.

Thanks I’ll check it out 

 

seems like popular think for someone to bing in and have on hand in the states

SlixSprings has an aftermarket lever safety/trigger return spring.  That’s a single spring in a Miroku; two separate springs in a Uberti.

Shotgun Boogie knows a guy!! The one that Tex referred to.

 

I’m not sure if he’s got ‘em here yet. The maker is in Germany and I think they were working on availability here.

Just got off the phone with the gentleman from slixSprings
 

They have a safety lever spring only no other springs for the Morocco 73

they also offer a replacement firing pin for better ignition I grabbed two of each

 

he said when they’re gone, they won’t be replacing them to the line

 

And no plans to offer any, as he noted there is a significant variable in tolerance, and his other contacts in the industry also feel that they are not going to be offering any items in that direction

 

Sad that an item that has the great potential isn’t closer to what we’re looking for out of the box

 

Or That there isn’t a simpler way to get there

 

Just as a note if you haven’t tried one of the slixsprings 12 gauge ammo, check gauge and correction toll

i love mine 

 

I can attest that they work great and I ordered the second one this morning there in stock on his website best 50 bucks I ever spent.

There are few aftermarket parts because there are few Winchester Miroku 73s in circulation.  Not worth tooling up parts if you are only going to sell a handful.  The Miroku is designed differently than an original or the Uberti 73.  What are you trying to accomplish?  I have found that due to the lack of aftermarket parts and the scarcity of factory replacement parts a few little cautious tweaks to the Miroku make a big difference.  For example, the lifter and lever springs on the Miroku (top) are basically flat and quite flexible.  When installed they have very little bend in them.  The Uberti and Winchester and quite arched and very stiff and as you tighten them they straighten out quite a lot.

 

 

What I have found that works quite well is to simply put a washer between the spring and the seat.  This makes a noticeable difference since as previously noted there is very little bend in the springs when they are installed.

 

 

 

The mainspring has the same characteristics.  It is relatively flat and does not flex near as much as the Uberti or Winchester.  EXTREME caution needs to be excercised if you are going to attempt to modify the factory spring unless you have a replacement in hand.  It can go from plenty of pressure to almost none with just a few thousands of an inch of material removed from it.
