"The court has to send an appropriate message that anyone pinching firearms is going to jail."
Litt had two previous convictions for firearms offences and was on intensive supervision when he stole the gun from Hunting and Fishing in Rust Ave.
Judge Davis said guns had been previously been described as an "anathema of the community" and in the wrong hands disasters could happen.
"Look no further than Mount Tiger Rd to understand fully what firearms in the wrong hands can actually do."
In that case Quinn Patterson - who did not have a firearms licence and had an arsenal of illegal guns - brutally murdered Wendy and Natanya Campbell and wounded Jeff Pipe during a property inspection at the Mount Tiger Rd home Patterson was renting in July last year.
Judge Davis called for an updated pre sentence report to consider what options were available but said jail was the likely outcome for Litt.
A police summary of facts said Litt went into Hunting and Fishing on Rust Ave about 4.20pm where he spent several minutes looking at the firearms and ammunition.
Four minutes later, he was in front of the firearms display where the Chiappa rifle was stored. He grabbed the firearm and was able to manoeuvre it past a metal barrier.
When a shop assistant walked by, he leaned it up against a shelf and circled the area a few times. Litt then took ammunition from a table and put it in a bag before hiding the firearm under his clothing and walking out without paying.
Two weeks later police searched Litt's Maungakaramea property where he showed them where the rifle was hidden in scrub near his house. Litt was remanded on bail to November 29 for sentencing.
