Being old, and long retired, most of my professional carry and use was with revolvers. PPC competition back then was with revolvers, albeit extensively modified. Thus I like revolvers, and always will. Most of what I own are revolvers, DA and SA.
That said though, for carry use I prefer a semi-auto, going back to my department's initial allowance to carry semi-autos personally purchased or the dept issue S&W 686 revolver, and then forward. Our jurisdiction had and has a major gang problem. These brave warriors travel and operate in packs, not solo. It follows then that maximum handgun capacity is prudent preparation.
In teaching new shooters, and coaching experienced shooters, I have not seen any ability to accurately shoot a revolver that did not carry over into shooting a semi-auto. If a person has a working knowledge of the basic fundamentals, and applies them, they will be skilled with either. I have lost count of shooters claiming their gun won't shoot, until I show them it can. Then it is up to the shooter. The tool is fine.
I have many friends who carry only revolvers. They know I prefer a semi-auto and why. There is no conflict. If one wants to take 'pride' in their preference, that is their prerogative.
As far as feeling like a plastic gun, other than subjective preference I don't see that as an issue. Plastic guns have long since proven themselves to be almost indestructible. Military and LE agencies have long since concluded that plastic is a viable material for the tasks intended.
On to Glock for a moment, since they have been mentioned in this thread. The scariest sound in the jungle is 'click'. Glock has established an enviable record of durability and reliability, despite the naysayers. So I have a very high expectation I will never hear that dreaded 'click'. But if something else comes along that convinces me it is even more reliable, I will buy it.
That has nothing to do with pride, and everything to do with practicality.
