Worked great

Yes Folks this is a drop in part. I have never had to do any adjusting or fitting for this part. Everyday lightened firing pin springs works just fine. Have I ever had one break. Who's any brand anything has not broken at some point. These last a long time. Buy a two! One for backup!

So few upgrade parts are available for Winchester Miroku 83’ rifle. Feel get better ignition with this part

Ordered Firing Pin and Lightened Trigger Sping. Installed both with Noticable improvement!!

These springs and firing pins worked so nice on my Miroku Winchester 1873's I ordered more sets as spare parts.

I had gotten some of the springs and pins. I had been putting off doing a spring. I found a utube video on disassembling a Miroku. It went easier than I thought. I did both of my rifles this morning, springs and pins. I was glad once again I had my screw driver bit set. The lightened spring makes a huge difference in closing the lever. I am very happy. Great products!

Fire pin worked great, solved light strike issue in 66.

Replaced my factory spring. Worked like a charm! Much easier and quicker lever action. Highly recommend.

Both easy to install and work fine. Big improvement with the lighter trigger safety spring.

Product was as represented, was simple to install; and, significantly reduced trigger safety pressure for cowboy action shooting. Definitely improves the Miroku lever action!

Installed this Pin and Safety Spring. I could tell it was smoothing the lever action. Never fired a shot. Went to a Cowboy Action Event and my other rifle jammed.. Bad Ammo! I went to my Miroku backup. Worked like a charm. 10 - rounds on a Nevada continuous sweep, No Problems!

The firing pin fit like a glove with no fitting. The safety lever spring now allows me to set my lever even quicker and I can adjust and lighten the tension on my trigger main spring. This makes the trigger oh so much smoother. Don't adjust out to much tension or you will get light primer strikes. If you do just kick that trigger back and try again. Later you can adjust for more tension to relieve that problem. That's the Cowboy Way!

The parts worked great no problems ,I always expect great results from Slixprings and never disappointed.

If you have a Miroku 1873, these are easy to install and make your rifle perform like it should. Highly recommended!

This is the first step you should take to slick up your 73. Get the firing pin while your at it.

I could have not been happier to discover a replacement spring for my Miroku 73. As folks know parts for the Miroku Winchester are hard to find, if not impossible. The is a perfect match for the original, if not better and lighter. Looking foward to this weekend to test it out.

I noticed a difference in the feel. happy with my purchase.

It helped some but the difference is very small. I will keep it in the gun because I don't want to dissemble it again.

It is also designed to provide greater reliability than the factory spring.

This is a great upgrade. Well worth it. Thanks for offering it.
