Sometimes people will be bothered by another person simply doing something different.
Some people will not be able to stand the thought of taking a "collectable" firearm and going out and shooting it. We have one poster here who frequently tells people to take any leather holster they get with an S&W revolver and quickly through it as far as possible away from them, since God Forbid, the gun actually gets some holster wear, and over the course of using and shooting it for 30 years, you lose a small percentage of its value.
In this thread we have a good example this myopic thought process. Just because a person at age X can use iron sights well enough to hit at a certain range, definitely does not mean others can. For a great many people, iron sights are difficult to use, due to them no longer being in focus. Some can use red dot optics as a solution. For them the RDOs work exceptionally well, and if it means modifying their guns so they can continue to enjoy shooting, that makes sense.
For some people, red dot optics do not work, as the actual red dot appears as a cluster of grapes due to astigmatisms and other vision related issues. For them traditional optics with crosshairs are a solution that allows them to enjoy their handguns. whatever it takes to allow the shooter to enjoy shooting.
I know "for me" using a red dot, rather than irons, even at 25 yards, the performance difference is significant. I can shoot FAR tighter groups utilizing a handgun equipped with a red dot, versus one with irons.
Below is a good example of that. a few weeks ago I was out shooting. I was shooting a 5" Model 29 with RDO, and a 7.5" Ruger Flattop. In both guns I was shooting the same .44 Special 240 grain hardcast load, that runs right at 900 FPS in the 5" M29.
With the 5" M29 at 25 yards, the gun shoots little tiny clusters.
Below, and left you can see the group using the 7.5" Blackhawk. Now one thing should be noted. The gun had previously been sighted in for a 300 grain load at a different range, so it was not even close to point of aim/point of impact. But the group size is the important part. If you include the "Flyer" in the group, the group is 3"s (I measured it later). It opened the group from about 1& 3/4 out to 3"s. The groups with shot with the red dot are all just little cloverleaf types. The simple fact is that I cannot shoot those cloverleaf type groups with iron sights. Not at 50+ years old. When I need to confirm accuracy, do load development for commercial loads, etc. I don't use iron sight guns.
So, if someone want to drill and tap revolver to make it better for them, let them.
BTW Pacecars,
I took this 8 & 3/8ths" Model 29-2 .44 Mag that was in extremely nice condition
This is in the same valley/ same area, as Elmer. A place on Idaho's Pahsimeroi Valley.
And I had a custom smith chop it to build me my perfect 5" Model 29.
