S&W's reply will likely be something along the lines of you shouldn't be messing with THEIR sights.
The real answer is the unfortunate problem with your sights is simply a symptom of S&W's current philosophy----the REAL problem! That philosophy goes like this: We will be successful if we build our products at the lowest possible cost. That following their philosophy of their first hundred years---We will be successful if we build the best possible product for the price.
This change can likely be traced to whoever owned S&W after the ownership changed from the Wessons. I'm not up to date on those changes from then to now---since I pretty much lost interest after what I suppose was the first one------mid 1950's thereabouts?
I doubt there will be a return to "the good old days" for so long as there's an emerging body of customers who don't know any better---or a change of ownership to one who does know better.
In the meantime, I'm glad every single one of the 200 or so S&W products I've owned over the years was built prior to the mid 1950's-----and NONE of them manifested ANY problems whatsoever. That, at least, is something they can be proud of-----if there's anybody left there who's proud of anything besides a satisfactory bottom line.
And now that I've run my mouth---and checked my records, I'm obliged to issue a correction: I've owned six S&W products at least shipped after the mid 1950's--- those being a Model of 1955, a Model 41, another Model 41, a SAO K-38 (Model 14-3), a Model 41-1, and a Model 52-2 (that one shipped as far into the not so good old days as 1980)------and each and every one of them was entirely satisfactory! Dumb luck?
