I have one, and they do make good little plinkers. Surprisingly accurate, too. The slide and frame material are soft, so they won't last forever, but if you keep it well lubed (especially the bottom of the slide that rides over the hammer), it should serve you for awhile.
The slide mounted safety will start falling down into the "on" position after awhile, but this is nothing a little super glue won't fix. I also removed the mag safety from mine.
You should still be able to find the range kit (5" barrel and magazine w/extended base) for about $35. Good to have.
