the keltec is way better, if it is a model made in the last 1 or two, then it has a decent front site. If it is older, it has the stupid, adjust with a quarter in the huge front slot, front site. you can also get an after market buttpad and front post accesory rail, if you wanna 'trick" it out a little. if it is one that takes glock mags, they are the best. If it is not a glock , then hopefully it is the one that takes s&w mags. They are cheaper. make sure the mag well isn't so tight that the mags don't hang up inside a little, when you use the mag release.
The hi point is cool because you can get an after market stock assembly, and it becoms way better. they also have a fully adjustable rear site, and a rail all the way down the top of the receiver. but your mags will be expensive, and they will suck, and they will be limited to 10 rounders.
Also , if you do get the keltec, go get some tubular foam padding, and cut and glue on the tubestock, your face will thank you for it.
