I will modify any gun that I have to make it more user friendly and more accurate in case I need it. I do not care what the courts or attorneys have to say about it. I want to survive a gun fight. And more efficient firearms will allow me to do that.
No argument there (as to survival).
I was only mentioning that you still may have to pay attorneys to fight (or at least prepare for the possibility) that the prosecution will try to inject "firearm" embellishments into the case.
I had a vendor-payment case years ago where the vendor was making up all kinds of indefensible BS. (probably with the intent to wear me down, to a more advantageous settlement?)
Like -- crazy person stuff.
I still had to spend the legal fees.
In the end, we settled that case, so I can't really say where the exact money breakdowns occurred.
There's a saying out there that the attorneys are the only ones who really "win" (or something like that).
I would rather all that extraneous BS been kept out of the case --- and in retrospect, I don't think I would do anything to actually encourage it.
So, if my carry guns don't really benefit from modification for my purposes (and mine don't, in my opinion), I see no need to modify them.
If the gun manufacturer gets embroiled into the case (a foreseeable possibility), I can picture their attempt to exit upon the very slightest hint that the weapon had been modified without factory permission, even if in the tiniest respect. (to their advantage to exit). Of course, you could spend more money in attorney fees to fight such an exit, if having the firearms manufacturer "on your side" helps your case any.
For me, it's the same thing with "overly deadly-sounding" ammo names.
I'd rather defend the same brand name the police use, than ammo with a name like "thug killer". For example.
Also, taken to the absurd extreme, one could modify their weapons for fully-automatic fire.
I mean, assuming such modification made the firearm more "user friendly" and/or "more accurate".
That does seem absurd (to me), and also illegal -- which at the very least strongly suggest that there
must be some sort of continuum upon which to draw a reasonable line on firearm embellishments. I don't know what, or where, that line might be, and I have zero interest in personally finding out.
