Save your money. Put it in a savings account at a bank, and add to it every time you get any income.
When you have $400.00 to $600.00, invest it in a slightly-used pistol of well-known make. Buy it at a reputable gun shop where the clerks know what they're talking about, and the owner will refund your money if the gun turns out to be a dud.
Pistols called things like "Commanche" and "Vindicator" and "Avenger" are almost always poorly made of pot-metal.
