The 24-year-old has already had loan spells at Forfar and Cowdenbeath but will now look to ship out of Ibrox once again in a quest to make a career for himself between the sticks.
Gallacher featured in last night's routine win over Berwick Rangers in the Ramsdens Cup, but he is well aware that the stage he is at in his career means he desperately needs to be playing every week.
The keeper had played second fiddle to Neil Alexander last term and before that was down the pecking order when Allan McGregor was at Ibrox.
This summer's arrival of Cammy Bell has blocked his path to the senior side once more and regular football is now a necessity.
Ally McCoist suggested this week that Gallacher is good enough to play in the SPFL every week, but the onus now is on the stopper to prove it.
"I would like to get to a stage where I am playing every week," he said.
"I have spoken to the manager and I know that I have to go and show what I can do elsewhere.
"It is an opportunity for me to go and try and catch the eye if I am doing the business at another club.
"I think I have learned a lot from working alongside the goalkeepers that I have worked with at Rangers.
"But I have watched others have their turn to play and now I feel as though it is mine."
Meanwhile, McCoist last night claimed he would still be interested in exploring a deal to get Kenny Miller back to Ibrox for a third stint -despite the fact the striker has just signed an extension to his deal in Canada.
The 33-year-old, who has just announced his retirement from international football, is contracted to Vancouver Whitecaps in the MLS until June of next year.
He would need to sever his contract before any deal could be done to take him to Rangers since the Ibrox side are still in the midst of a transfer embargo until September and the window closes at 5pm on Saturday evening.
It is unlikely any move could be agreed for the player and even if there was a surprise on the cards, it's likely that it would need to be a player for January rather than an imminent signing.
"Kenny is one who would interest me - I'd be lying if I said he didn't interest me quite a lot," he said.
"If there was an opportunity to get Kenny I wouldn't be doing my job if I didn't explore that but we have to wait and see.
"I haven't spoken to Kenny since the day after the Scotland v England game, and I haven't spoken to him about coming here.
"I would not rule that out. If it was a possibility I would be very interested in that.
"I'll certainly be making inquiries in the next 24 hours."
