Is this good practice? Joining two objects after subdivision I would like to know if this is good practice in joining two objects (in my case a sword pommel with a handgrip).  

The handgrip has a shade smooth and the pommel has a mirror and subdivision modifier.

Am I doing good to stretch the Pommel's mesh till it joins well with the handgrip (it appears correct when I switch to object mode)?

Is this correct practice, keeping in mind that I want to make all objects forming the sword a single object in the future?

I am asking to avoid possible future errors.
There isn't one right way, use what works best for you :)



You can either join objects into one object (CTRL+J) consisting of multiple meshes    
Or even join into one mesh, with all vertices manually connected (seamless)




Example
This sword is one object consisting of multiple meshes 


Easy to swap different parts 
It resembles a real sword structure which adds to realism
