I got 597 a few months ago for plinking. I had a little trouble loading the mag that came with it at first however the extra mag i bought with it loaded a lot easier. not sure why. also there's a 30 round hi-cap banana clip that for the 597 that's really easy to load and give you 20 more shots per clip. it's UPC is 047700196688. about $25 in stores but $15 online (I bought 5 from impactsports.com). carrying 5 banana clips in my shooters bag is a lot easier than having to stop and reload every ten shots.
