huntsman: hte Hi-Point pistols have been written up in the Gun Tests magazine and have been found to be inconsistent in both quality and reliability. Some work well, others not at all. I would avoid them as they do not seem to be a good deal in any regard.
If you are looking for inexpensive pistols and want to start with a 9mm, go through your latest Shotgun News and take a look at the used european police pistols like the Walther 9mms - absolutely solid and reliable. You can also find Tokarev pistols in both 7.62x25 and 9mm at very reasonable prices. For an oddity, there is the Chech pistol that appears to be a design combination of the Walther P-38 and something else - again, solid and reliable. Those are the 9mms.
In the 45 caliber range, you can find Norinco copies of the 1911A1, or the Rock Island (?) copy as well - these are not used pistols but new and will go you a couple of hundred dollars. HTH. Mikey.
