NOT MY PHOTO
Looks like from the back of the folding part of the stock to the start of the barrel is apx 9 inches.
The TD comes in 2 factory barrel lengths:
16.62"
18.50"
So it looks like the 16.62" would just be slightly too short at 25.62"
But it has a threaded barrel, I am not sure if Ruger is measuring the length of the muzzle device. It might be possible to add a longer muzzle device to bring it up to length.
The 18.50" would be slightly over the 26" OAL with 27.5".
Again these are just guesses using a photo and some stats off a website..
