Pay bills.
However, if I had to spend the money on guns...
Tough one. At this point, I'd probably get:
Another 642-1 (or two).
A couple of 640NDs (at least).
Trigger jobs on the snubs, if needed.
3 identical compact double stack 9mms, leaning towards either Sig P229s or Glock 19s.
Accessories for the semi-autos (holster, mag pouches, mags).
A good semi-auto rifle (or three), leaning towards a good AR15 carbine, possibly in 9mm (don't judge me!).
Training classes (tactical first aid, defensive pistol/rifle shooting, force-on-force, etc.).
Maybe a nice, custom 1911...or Hi-Power...or both.
Use whatever's left to stock up on ammo.
