Well, since most places or people find no offense in the word "bend" we can use it here!
I have had a few Rugers cross my path that had either a leg of one side of the trigger return spring unhooked,, or a modified bent spring. And of course,, I've had aftermarket springs in guns tried here as well.
Every time I see this stuff, I fall back upon some of the world's best shooters I've had discussions with,, that agrees with my hands on experience. A proper action job, done by a person who understands the actions & how they work,, easily trumps any such alterations by the average person.
I have a factory built,, El Dorado SA handgun,, that many SWEAR it has a hair trigger. Or they think it's got less than a 1 lb pull. When I show them the trigger pull using a gauge,, and it takes 2.7 lbs,, they are amazed.
Simply put,, a gun is a manual, mechanical machine. To make it work smoother & more efficiently,, the parts need to be properly fitted & work together & not against each other when operating. The term; "Well oiled machine" is a great way to paraphrase it sorta.
Bending parts, or taking parts & modifying how they work is not the best way to get a get a mechanical machine to work as smoothly as it can.
Often,, we hear how a S&W revolver has a much nicer action or smoother action right out of the box. Well, when you look at the internals of a S&W vs a Ruger,, you see more parts, working in a different manner,, that HAD to be fitted to closer tolerances to work. As such,, not only the design,, but the fitting of the parts was done differently,, and the result is a smoother feeling action.
But I've also seen quite a few Ruger revolvers,, when the same time & treatment of their fitted parts were given extra care & fitment,, feel smoother than a S&W.
That said,, many people feel that a gun should be "perfect" right out of the box,, or try to compare apples to oranges when looking at them. Throw in how many may not want to spend extra money to have a proper action job done, but are willing to spend a few bucks in such parts as springs etc hoping for an improvement.
But most gunsmiths,, including many home types,, (NOT Bubba's) who have a basic understanding of the internals of a revolver,, can disassemble one, and easily learn how to smooth off rough spots or edges. They will often get a much better revolver feel by simply "de-burring" tiny edges or rough spots in the internals.
Others,, (and this has been done a lot) will just clean the internals,, fill it with a mild abrasive,, such as toothpaste, or even a good oil,, and dry fire it a lot. This too will work in smoothing off those tiny places where the internal parts fit & operate together.
Many are the well used but cared for Rugers that have just been operated enough to smooth them up a lot.
These thoughts if mine have been proven time & time again,, but are often overlooked by people wanting a "quick fix!"
