+1 on "Sorry to hear about the loss of your other firearms."
Congrats on a fine new one.
The "magnum" frame Model 60 will not fit in some model 60 holsters. I've found this particularly true of closed end models. That said, there are a lot of options. I like the Uncle Mike nylon IWB holster for concealed carry here in Arizona. The handle fits closer to the belt line (YMMV) and is more concealable for me under a light shirt. Draw is easy, but you almost have to undress to re-holster it.
In the field, I've settled on an Uncle Mike's cartridge belt and size 0 strap retention holster.
Polishing the rebound slide and corresponding frame surfaces significantly improved the double action pull on mine.
Lot of grips and adapters available to meet your needs. For the moment, I favor the Vintage industries boot grip.
Feed it what you want; full house, 158 grain Magnum loads can be stout.
I prefer Remington .38 spl +P, 158gr. lead, semi-wad cutter, hollow points for most carry situations.
Though I use speed loaders some, I mostly carry Bianchi Speed strips for from-the-pocket reloads.
I'm still loathe to change the front sight out, but I have an XS express night sight fitted for mine. I'm waiting on the correct drill bit to arrive and may try it for a while. I did deepen and open up the rear sight some years ago. If I had the green, I would have the
Bowen high-visibility sights put on it.
You are going to like your Model 60
