In many ways, only you can answer that question and to do that, you have to answer a few other questions.
Do you already reload?
If so, do you have a turret or progressive press? (Reloading handgun in any sort of volume on a Single Stage gets old really quickly.)
How valuable is your "free time" and how much time are you willing to invest in reloading?
Would you rather spend that time reloading or shooting (all other things being equal)?
Unless you are doing some very precise shooting, handgun ammo is significantly less "finicky" than rifle ammo when it comes to reloading. I shoot IDPA at my local club, and at the end of the night, those of us who reload split up the used brass. We typically go home with a mixed bag of brass. I personally don't sort it by type/manufacturer, but after I take a look and check for damage, I reload what is left.
As with all reloading, if you decide to do it, take your time and be safe.
