Okay, since others have already mentioned some PROPER sporting guns, I'll go ahead and say it.
Buy once, cry once. It's very simple, I can shoot as well (rare as I may be) as guys with K-80's, and I, (with an A400 Excel) be shown up by a kid with an 870.
That being said, you can skip a few painful and expense steps by just getting fitted with the RIGHT gun and being done with it.
I shot a 625 Golden Clays tonight just to feel it out, Im now on a mission to own one.
You can buy 4 guns over the next three years and cry 4 times, or you can pony up the cash ( the cry ONCE part) and have a fine crafted TOOL for the rest of your life, 100K+ rounds no problem.
But: You can never have too many shotguns
ps: There are Browning people and there are Beretta people. They feel and swing differently. Those who like one B don't often like the other. Try em then buy em.
