veggie,
You have received lots of good posts here. I'll add my comments for what they are worth, as a seasoned intern in this fun world of S&W's.
The use of rare, scarce, desireable, collectible (and others) comes up a lot in the gun world, sometimes it's even accurate. Now, your original question - to me - indicates concern over ruining either some collector value, or $$, is that correct?
As Sebago Son indicates, once fired it's going to have a financial impact - probably but not necessarily all the time. Some folks will pay more for absolutely NIB, no doubt.
But let's take a look at that particular model, IMO it's neat, highly desireable to a lot of folks and somewhat scarce (sort of), but rare - no, and from a pure collectible standpoint it's questionable if it is there - yet.
Some folks really like these guns, me included. Some folks are really into accumulating all variations of certain models, me included. Some folks are truly into collecting valuable and interesting/noteworthy guns, but while this one has some good attributes, I'd have to say it's not really collectible (yet), along with probably 90% of the guns made since ~ 1980 or so (heck, maybe even back to the 1970's).
For something to be collectible, there not only needs to be the case for calling it that (noteworthy history, small quantities made, unique circumstances around it's manufacture, wierd variation, etc.), and it also has to have - to some degree - a market, or some sort of following that is willing to pay or seek out that gun from the standpoint of it's noteworthy history, small quantities made, unique circumstances around it's manufacture, wierd variation, etc.
My opinion, like most everyone here, is to shoot it, enjoy it, take care of it and experience what you - hopefully - were looking for when you bought it.
Enjoy.
