You have not shot one. I am shooting one everyday, and I believe the targets easily.
The Sig is 2 pounds heavier and a single shot. If i wanted to spend 500$ on a break barrel, I most certainly would not pick the Sig.
I shoot my sig regularly with well over 4000 rounds through it. First, I didn't pay $500, and second i can tell you mine is absolutely wonderful. Worth every penny I paid, and I can easily stack pellets with it every time I pick it up. Shot cycle is smooth and easy, trigger is very good and crisp, overall experience with this gun is fantastic. It is slightly pellet picky, and slightly hold sensitive, but a wonderful gun with a great brand to back it.
having said that, I favor shooting my non-break barrels such as my Diana 48 which I find to be more pellet picky, more hold sensitive as well as slightly less accurate for me.I
To each his own. What a wonderful hobby.
