Another Glock fan! You'll fit in well here :) There's been several 26's posted in the last week or two and 19's are also very popular. Good luck with your search.
Agreed and it also partly depends on the caliber. For example, you don't want to shoot steel with .22 as it's already prone to ricochet. Pistol calibers are generally safe as they loose energy quickly but as Adam noted, put enough distance in between you and the target just to be safe.
here's an addiction for you - it's the home page on my laptop, my iphone, and my ipad. Sad, I know. Just wait until you "miss" a couple of reaaaalllly good deals and you'll want to keep checking every couple of minutes yourself!
