I guess I should mention now that others have brought it up, that I do own some other firearms that are considered collectible.
A NIB flatlatch M36. This one still had sawdust in the grip checkering when I got it. I don't shoot it. Not because its particularly valuable or rare ,
I'm sure the amount of sock drawer NIB M36's, even old ones, is longer than most guns,
There is just no reason to shoot this. I just don't think shooting a snubnose .38 with S&W factory wood grips is fun.
I get far more enjoyment looking at it in its present condition than I would shooting it just for the sake of shooting it.
I have an Astra Terminator that I don't shoot much, if at all these days.
Not because its valuable, although certainly more valuable than when I bought it,
Not because its not fun, because it is with .44spcls or mild .44mags,
I don't shoot it because if anything breaks...Astra hasn't been in business for decades and spare parts are hens teeth.
I have a Nazi ppk, an RSHA gun.
I don't shoot it. Not because its in great condition, its not.
Not because its particularly valuable..it isn't, in its condition.
I don't shoot it because its not fun to shoot, even in .32. I shot a few rounds and let a buddy shoot a few, a magazine total, then cleaned it and put it up. That was 15 years ago.
Its a snappy little cuss with an uncomfortable grip.
I have a S&W 10-8 in nickel that I'm pretty sure is unfired since leaving the factory, still wearing the carbon burns on the face of every other chamber on the cylinder...which is how the factory test fired them.
I don't and won't shoot it.
Not because its particularly valuable, it isn't.
Not because its particularly rare, it isn't
Not because it wouldn't be fun, it would
I don't shoot it because it wouldn't be as smooth as my well used 10-8, and I like seeing a true representation of the quality S&W was turning out for nickel guns at the time. Honestly not that great.
There are a lot of guns I have in my safe that don't get shot, mostly because I reach around them and grab the guns that are better for that instead.
