Not All Modifications Are The Same....
I have cold chills reading many posts on gun boards. All the talk of cutting barrels, filing sights, cutting trigger guards, etc, etc. I think back over the years when I too have ruined perfectly good guns, mostly rifles, "customizing" them. Have turned several $700.00 rifles into $300.00 rifles. Smith & Wesson makes the best handguns (revolvers) in the world. Personally I see no advantage in changing anything on them.
Like any gross generalization there is some truth to what you say but plenty I disagree with as well.
Granted some aftermarket custom work especially porting of concealed carry guns appears downright silly and wasteful to me. I also share your distaste for guns that have been butchered by aftermarket modifications.
However, no gun manufacturer can make guns that are suited to everyone's needs. I Agree S&W is one of the finest gun makers today, along with Ruger and a couple of others. My personal preference runs to S&W third generation semi-autos and pretty much a tie with Ruger and S&W for revolvers. That does not mean they are the best, just for me they are what I like and trust.
I have a couple of M64 that were police issue that have the worst triggers of any of my guns including my Rugers. Now should I just live with that or is it OK with you if I do a trigger job on them?
I have several S&W N frame revolvers with blocky style black target sights and some K/L frame with just plain silver ramp sights that are difficult for my old eyes to see. Is it alright with you if I put some nice red ramp front sights on them?
I also have a couple of older SS S&W revolvers with serious scratches and some rust under the grip (yes SS will rust) that I picked up at a gun show for a good price. Is it alright with you if I polish them up do a deep cleaning on them and replace the but* ugly target grips that are too large for my needs? They are actually mechanically very sound and tight, but were just left out in a truck or in some tackle box I guess.
As I have aged I developed arthritis in my hands which is making me more and more recoil sensitive. Is it OK for me to put Pachmayr rubber grips that cover the blackstrap on them which greatly reduces the felt recoil?
Also I truly like three inch revolvers, but many of them especially a M610 and the M625 are quite pricey. If I ever pick up a really cheap 5 inch version of a 610 I may well have a gun smith cut the barrel and recrown it. So far I have not seen one where it would be cost effective to do so, so I keep looking for a 610 that is priced where I am willing to buy it.
There may be a situation where I would have a cylinder cut to take moon clips, if I found just the right gun at just the right price so it would be cost effective. So far I have not.
To date my after market modifications have been for sights easier to see, triggers easier to pull, and grips to reduce felt recoil, but frankly once I buy a gun I own it and feel it is mine to modify as I see fit, even if that modification reduces its value to the general public.
I do agree with you that some of the modifications, especially some of the do-it-your-self modifications can turn a 700 dollar gun into a 300 dollar gun, but that is most often a function of limited intelligence in that specific instance, and should not be used to make light of all after market modifications.
Even S&W will do after market improvements on their own guns for a price, so I don't consider mass manufactured guns to be some kind of holy grail that cannot be improved upon. Remember not all people are the same in their likes and dislikes.
To summarize you cannot lump all modifications into one basket and label them all as good or label them all as silly and wasteful.
