There are a number of ways to have fun with a semi auto handgun....I have a "wrooger" and it's OK but wouldn't necessarily recommend it because it's the only semi auto I've owned......I prefer revolvers!
This much is a given however....the main purpose of these guns is self defense and since by definition "self defense never happens at 100 yards"....I say that accuracy, while important, isn't the primary concern....it's reliability.....
Whichever 9mm you choose remember that if it isn't completely reliable then the .40 and .45 you get later should be a different make....
Also remember this....if it's self defense you're interested in, then a shotgun is still your best investment.....
Have fun....I like my 9mm for just plain rolling blocks of wood around the back yard.....but it's not my defense gun !
