No my only reference to the model 597 Remington is for a 22lr semi-auto rifle.
No
Do a search for Jarvis. They make a bull barrel for the $597, it runs $198 in either blued or stainless.

Remington does make a combo shotgun rifle, the Model SPR94.
No winchester makes a model 1300 shotgun.
Yes, but, expect to pay for it.
No.
No. The stocks are not interchangeable. Boyds make some nice aftermarket stocks for the Remington 597 as well as the Ruger 10/22. The Ruger 10/22 has all sorts of aftermarket parts to customize the look and performance of your 10/22. The Remington 597 is just now beginning to get more aftermarket products available to customize your rifle.
i bought my 597 for $200 but you could proabobly find one that's cheaper.
I have no idea what you mean. Every Remington shotgun ever made was designated as a shotgun, and had a model name or number. If you clarify your question, maybe someone can help.
