Stock MkIII tune-up?

Am wondering what I can do with the stock MKIII ( without buying new parts ) to get the trigger to function better, plus anything else I can do to improve function.

The gun is 100% out of the box stock, except the front sight was replaced with the front sight from a Marlin model 60 rifle. ( They swap out, strangely enough. )

You can polish the hammer and sear surfaces to make it smoother. Without a MKII bushing you will still have to deal with the mag disconnect unless you use a washer/spacer. You can activate the pre travel set screw in the trigger (inside frame) then you will need to take the nub off the trigger that lifts the mag.

The only part I bought for mine was the Clark MKII Bushing. I reworked all the parts. My Lyman digital pull gauge tells me my trigger is a very light 1 lb 9 oz. :D :D

I still haven't taken the gun apart to try and slick it up a bit - but fooling around in the shop, I tried putting a CCI CB Short in the magazine, way back where the rim is supposed to be in the magazine - and I discovered that the gun would chamber and fire the CB Short just fine.

The CB Short didn't have enough horsepower to budge the bolt of course, but it fired just fine with hardly any noise.

Something good to know in an urban pest situation, as long as the pest wasn't too big, or too far away.

You say a CB short will fire in the MK III fine; do you know if the same is true with a .22l?

It shouldn't be much different than lr. Might have bolt cycling issues. My guess. I don't recall buying .22l. If I used any it would have been in a bolt action rifle.
