Mags for sure. You're thumb gets tore up loading that 10 round baby you get with it.
A mag loader is a good investment, I don't have one, but my Dad does and I use it at the range. Real time and skin saver.
The pull on mine (carbine) was also a little short, so I got an an2" thick recoil pad off ebay and it extended the length so it was a little more natural.
Also got an extended magazine release off ebay. A must have!
Cost me about $4 and was easy to install.
That's all I've done to mine.
Love that .22
