Original Smith trigger

[Bob Bumleg]

My original Smith carbine has a heavy trigger. Do any gunsmith at the Fall Nationals do trigger jobs on these?

No, you have to buy a new gun

Ask Bruce Cobb for a Yeck mainspring

[Michael Bodner]

Very often, the cause of a heavy trigger on the Smith is the trigger return spring and NOT the mainspring...

I recommend you first remove the trigger spring and then measure your trigger pull. If that lowers the pull, then reduce the overall height of the trigger spring.

NOTE: To reduce spring tension on a leaf spring, you reduce the height of the spring, NOT the thickness.....

Of course, if that isn't causing your heavy trigger, either go with a lighter mainspring, or work the sear/tumbler angle like

Who ever dreamed up the coiled spring idea is a genius. Technology wins out on this one! Thanks go to Bill.

Hello, all:

Just went through this process with a minty, 100% unaltered original second version #10,57X, from Tom Nixon.

As purchased (lightly lubed) trigger pull, with the Carbine firmly set in MTM cradle, ranged between 9#2oz and 9#5oz using a Lyman digital scale.

Loosening the mainspring screw one, two and three turns, just for curiosity, produced maybe an ounce or three lower pull weight. Am not sure that a loosened screw/ mainspring will allow the butt stock to refit. Mine is tight everywhere.

Replacing the original mainspring with a Larry Galahon one from S&S reduced pull weight a couple ounces, BUT THE COCKING EFFORT WAS MUCH LESS! So, mainspring didn’t appear to be the issue.

Tried BOTH a Galahon “gull” copy (S&S) and a COIL version from Lodgewood. WOW.
The “retro gull” was useless - hole cockeyed and a bit too small for the pin, BUT the coil dropped in fine and pull instantly became, with a Galahon easier cocking mainspring, 3# plus HOWEVER MANY OUNCES YOU WISH, via careful bending of the arm that contacts the trigger. Please note that the type of lube, especially moly based ones, if any, used on the contact surfaces WILL make a few ounces difference.

Am VERY HAPPY.

Respectfully,
Kevin Tinny
