World's Largest Handgun? .600 Nitro.......p-shaw!!!
That wonderful, trophy wife of mine, got myself and each of my 3 boys a .625 caliber, 6 shot revolver that uses caseless ammo. No more worrying about dumping the empties. No problems with policing the brass. No concern about micro-stamping. Ammo is plentiful and not very expensive. Handloading is easy and cheap as well.

Merry Christmas all.

No, but finding the damn darts is pretty tough. When I cleaned out the house I owned for 20-some years before selling it - after raising both boys in it - I can't tell you all of the "lost" toys I found - including Nerf darts, pizzas from the TMNT pizza shooter (trust me . . . ), etc.
With 4 of you having these, all I can say is - Enjoy!
PS: Nothing for me that I didn't buy. And I splurged through Sept-November, paying off the splurge, so no weapon-related goodies for me. I have got to get a new GF - for a whole lotta reasons!!!
