Went and looked at mine and my honest answer is, I don't know.

The hammer side extenstion is not an issue, it wouldn't interfere at all.

Seems like the sight by itself would be no more vulnerable to knocks and damage than any scope and it does stick out a lot less. It's made to take some serious G-forces since it's regularly used on the slides of semi-auto pistols.

I would worry more about scratching the lens but again, any scope would have that vulnerability as well. It comes with a plastic cover that protects the lens from dust and dirt but it just slips on and off and might be lost out hunting.

For a scabbard that Picatinny protector mount would sprobably provide the most security, but it would make the sight sit up higher.

Here's a pic of the sight in the mount and the sight alone on a rifle.

Gunnery, gunnery, gunnery.
Hit the target, all else is twaddle!
