Agreed. WHO sold him that weapon? WHO sold him the ammo?

WHERE did he practice?

With WHOM did he associate at the range.

Can’t imagine this guy could be so calm and accurate without prior practice and training. Army doesn’t provide much pistol training for its psychiatrists, and not with privately owned weapons.

He's an American citizen (or even if he was only an alien) with a valid driver's license, he could buy that weapon at many local gunstores for about $1k. Ammo is readily available, though rarer than .45 or 9mm.

No reason to go all anti-gun, track down the dealer on this. Unless he eluded any background check, no laws were violated.
