Hi Charlie,
Congrats on your P22 Target pistol. We have one as well and like it a lot.
I am curious about where you live insofar as you can shoot in you 'backyard'.
You must live in the country where it is OK to do so. Naturally you must have neighbors somewhere nearby. Again, depending on where you live, you must be careful not to violate any local ordinances, disturb of frighten anyone, and certainly not endanger anyone.

So if this is the case please tell us where in Alabama it is so we can make retirement plans.
I have seen a laser attachment on a P22 and they should be available through WaltherAmerica or your local gun-shop.
