I own a Glock 17 and am planning to do a little more target shooting than before. Does anyone have a recommendations for adjustable sights? Presently I have the standard fixed sights. Also, if anyone has any specific brand of target ammunition they favor, I'd welcome advice on that as well. I keep hollow points at home for protection, so I'm just looking for target ammo. Something at a good price with good results would suit me just fine. Bass Outdoor World usually has Winchester 9mm ammo (115 gr.) on sale ($21.50 per 100).
