SW pre model 10 strain screw
How tight do you tighten the strain screw on a old pre-model 10 Smith. At least I thank its called a strain screw, it puts pressure on the main spring. Thanks

If you have a correct screw and a correct spring, it's supposed to tightened all the way. That's the way they were designed. 0 -
I have a new Wolf reduced power spring. 0 -

Tighten it all the way like the factory one is [;)]0 -
The fact that this piece is a threaded screw leads people to think tension on the mainspring is adjustable in order to lighten trigger pull. The fact is it's designed this way only to ease disassembly. 0 -
Why is it called a pre model 10? That's like having a coin dated so many years BC.
I can't find any model on mine, just a series of patent dates ending in Dec 29, 1914.0 -
Prior to 1957 when S&W gave numeric model numbers to their handguns, it was called the Military & Police, in 1957 it was called the Model 10. 0 -
Like the guys have said, the proper tension on a strain screw is when the screw is pulled tight.
S&W's are often found with a strain screw that has been shortened, so the screw can be pulled tight while reducing the strain on the spring. This lightens the pull, granted, but S&W's engineers designed the whole system to have enough power to still work reliably under fairly adverse conditions. Given the inherently good DA pulls in Smith K-frames, I wonder why people just don't exercise their trigger finger, instead of marginalizing the reliability of their gun [?].0 -

It is strictly a modern collectors' term.
As TRAP55 said, S&W model numbers were assigned in 1957, before that, they had names.
To be a "Pre-Model 10" in collector-speak, it should be a post war Military & Police with short action. Yours, with 1914 patent date, is a Military & Police Hand Ejector, Model of 1905, Fourth Change, as made from 1915 til 1942. A collector would not call it a Pre-Model 10 because it does not have the same action as the post war guns.

The strain screw is meant to be turned down all the way. This may or may not be enough with the Wolf spring because the screw will hit the groove in the spring and not tension it as much as a flat standard spring. Good luck.0 -
This old Smith was made in 1902, Thanks for all the info. 0
