I have both and like the XS60C a lot better than the 1077. Trigger alone is worth it, but it's a single-shot.
wood and synth. worth the extra few bucks more for the hardwood version, IMO.
The XS60C, properly tuned, will take down small game and maintain good accuracy.
For a co2 repeater, I offer that you consider the Umarex Fusion 2.
Accurate, quiet, but you ain't gonna kill anything with it. 25Y at best on a calm day. But 15-yards or so, it's a very accurate co2 rifle out-of-the-box.
(and takes 88/90g tanks or the dual 12g)
Whatever you get, let us know!
