What model of Simmons is it?
I put a Simmons 8 Point on my 110 when I bought it. It was ok, but the eye relief is EXACTLY 3 inches. Any more or less and you lose the sight picture. On a long action rifle, it limited where I could mount it. After putting 60 rounds through the rifle, I decided to upgrade.
I replaced it with a Burris FFII (which I sighted in today). I was very pleased with the clarity and the longer / less restricted eye relief.
Try shooting the Simmons and see how it does for you. If I had been forced to use mine (like if I didn't have $200 to get the Burris), I could done fine with it. As it is, I kept it in case I get a short-action rifle or a carbine.
