"strip it down" means only a field strip, not neccesary to take down to the detail strip level- mof , you might be better off doing the field strip until you learn WHERE EVERYTHING GOES and are able to put it back together;
buying a norc from canada ammo doesn't really give us enough information as "norc" makes several varieties and calibers of handgun- and there's different procedures for each type-
but basically, pull the slide back, eject the mag, lock the slide back, use the lip of the mag to compress the recoil plig, rotate the barrel bushing until it comes loose( CAREFULLY, ITS UNDER TENSION)
then allow the spring to expand, take it out, then take out the slide stop, and slide the slide off the frame- then remove the guide rod ( that's the other half of where the recoil spring goes) and slide the barrel out of the slide- it doesn't matter whether it comes out the front or you angle it and take it out the back- then comes the thousands of q-tips and rags, - you want to clean the magwell as well then oil the rails , and reverse the order, trying NOT to get the idiot scratch when you put the slide stop back in- you also might want to clean the back of the chamber in the slide ( ie the firing pin hole) and push on the pin to make sure it makes contact
