A git loading safe weapon for kids (10)
I believe the answer is:
peashooter
'weapon for kids' is the definition.
'a git loading safe' is the wordplay.
'git' becomes 'shoo' (git can mean 'go away').
'loading' means one lot of letters goes inside another (some letters are loaded into others).
'safe' becomes 'peter' (I've seen this before).
'a'+'shoo'='ashoo'
'ashoo' going into 'peter' is 'PEASHOOTER'.
(Other definitions for peashooter that I've seen before include "Toy weapon" , "Child's "gun"" , "Primitive weapon" , "child's toy" .)
