I always carried TAP in my G23, I need more if I can ever find someone with a good selection of ammo in stock.
For general shooting, I buy whatever I can get cheap (which is a relative term anymore, the days of getting Winchester white box for $9.99 are long gone). A tad less accurate than TAP but a fraction the price and everything that is not premium shoots about the same.
Honestly, I haven't bought anything but self defense ammo in years. I handload everything but .22, it's the only way to stomach the cost of shooting any decent amount. I load whatever jacketed bullet I can get cheapest when I'm buying, to a very moderate powder charge of Blue Dot (because I had a lb on hand and it lasts forever in pistols).
Nice choice on the pistol. I love my G23 but the Springfield would be the other gun on top of my list.
