Haven't ever shot a .40, but own a 9mm Hi-Point that I bought from a fellow THR member a while back.
What can you say? A $100 gun with a $30 red dot that goes bang every time and is extremely accurate = fun in my book.
At the PA THR shoot this weekend, Spot77 and I were easily picking off clays from the 50 year berm from the standing position. It gets almost boring at 50 yards, it's so accurate. At 100 yards you have to think a little harder, but it's not at all hard to stay on target from that distance.
I don't think that I'd personally buy one new, but I've been very, very pleased with this inexpensive little firearm. I've probably gotten more enjoyment out of this gun on a dollar per dollar basis than any gun I own.
If you want it for a fun gun, I'd suggest getting it in 9mm so that you can shoot more.......
