So this is going to sound like a stupid newb question but I just purchased a new JTS 12 Gauge semi auto shotgun model # M12AK, in reading the main data specs it reads under Cartridges Used: 12 gauge "ball" Cartridges 2 3/4" and 3". Does this mean I should not shoot 3" rifled slugs?

Ron, you would be able to use both 2 3/" and 3" Slugs no issue Sir. Cheers and stay safe!

The reviews on their website says it runs slugs no problem

"So far I love this gun. I've only put 50 rounds or so through it so far. Im running 2 3/4 inch 1 oz rifled slugs. On the 2nd round the shell casing didn't completely eject. I changed the gas setting from 1 to 2 and it ran perfect the rest of the day. My question is, are there any plans to make larger capacity magazines? 5 rounds run quickly with a semiauto shotgun lol. This is my personal opinion but if there are not any larger capacity magazine in the works I will probably sell the gun and buy a saiga or something that gives me the option to have more rounds."

"I just got the M12AR from Sportsman Warehouse. I am impressed by how well it cycles all of the shells I put thru it. I have run High and Low Brass and so far, all is well. You need to adjust the gas settings for each type of shell, but thats to be expected. The settings are as follows:
"0" is for manual operation or 'single shot' use such as breaching

YES, rifled slugs are designed for a smoothbore shotgun (ironic right?). Be sure NOT to use SABOT SLUGS in your smooth bore (sabot slug for rifled shotgun and rifled slug for smoothbore), there can be off issues of the plastic getting stuck or something and blowing out the barrel, seen it IRL. It's Rifles Slugs with a Smoothbore or you swap barrels to a Rifled Shotgun Barrel and Use Sabot Slugs. M12AK has 3 inch chamber which means it will shoot anything 3inch or shorter. So it should work with both 2 3/4" and 3". I hope this helps!
