Garrett Co Hooligan #1
The M*CARBO trigger spring kits I installed in my TC Compass rifles made a world of difference. When I saw they had trigger upgrade kits for Mosins, I figured for $20 what the hell - give one a try in one of my old relics. So I picked this 1931 Izzy as the guinea pig.
Below is a YouTube link to the installation video. I won't bore you with the process. Installation is actually pretty simple.
A few things I learned were:

Below are some before and after pics I took at various steps during the installation. This rifle is going back to tomorrow's Hooligan shoot to see what it does at the range.
I think I've become a fan of M*Carbo stuff!

A few things I learned were:
- Now I know exactly how the trigger assembly works in my MN rifles.
- I had never thought about the "depression of the cocking piece" pointed out @ about 3:30 in the video. But it occurs in all of my Mosins. It kinda makes sense accuracy would be affected if the bolt is moving around before firing. After I installed the kit, that wobble is gone in this rifle.
- Sanding and polishing the sear and cocking piece engagement surfaces is simple. I could have done more on my first pass, but the surfaces are much improved.
- Two trigger shims come in the kit. There was so little side-to-side trigger play in this rifle I only used one.
- The trigger return spring installation is easy and does make a difference. This rifle now has what feels like a modern trigger.
- The "before" trigger pull on this rifle was ~ 6 lbs 10 oz. With the work done it's down to ~ 4 lbs 10 oz. And it's a LOT smoother. The kit was a helluva improvement!
