Another Gun Thread

Two Questions:

I just picked up a Ruger 10/22 and I was wondering what all of you suggested in the form of accessories / mods for this rifle. I bought it because .45 ammo is just too damn expensive to target shoot with.

My other gun is a Ruger P97 .45 ACP and I am looking for a good carry gun. My .45 is too big to conceal. I'd ideally like something that will fit in a pocket holster or will inside the waist band. (I wear a suit everyday).
I'm looking for:

.45 preferable because I already have all the reloading stuff for this but not a requirement.
No revolvers
Common ammo ie .45 9mm .380
Value / reliability.


Thanks in advance.
