I decided to exercise my 2nd Amendment right a few weeks ago. After months of research, discussions with friends and coworkers, I ended up with a Sig 229 9mm. I think I should have done more research on the different types of ammo however. Most Internet searches on ammo yield more questions. Is there a resource that "decodes" ammo terminology? You have fmj, parrabellum, Luger, p+, p++, steel jacket, hollow points, hydro shock, etc, etc. I am looking for recommendations for 124g rounds for break in and general target shooting. As far as maintaining my investment, is there preferred cleaning gear / products?
