Edward Leo, who runs Combat-UK in Broadwater Crescent, Stevenage, dressed up a spare female mannequin with a red and white trimmed suit, black sunglasses and replica gun and placed it in the window several weeks ago.
Mr Leo said: “At no time have we had a member of the public or customers raising any concerns regarding our Santa.
“At Combat-UK we embrace Christmas and Santa in his many forms.”Well, we can't let that stand, can we? Surely the local paper can dig up some prune-faced old biddy to purse her lips disapprovingly?
Rita Brian of Bragbury End told the Comet she did not find the joke funny.
The 65-year-old said: “The shop has always grated on me, but this Santa in the window is totally inappropriate. I know there is a school nearby and children have to walk past the shop every day.
“I have no problem with army surplus goods, it is just the weapons.”Bah humbug, Rita!
