I hate to be the bearer of bad news but Hi-point no longer makes the comp model. I know I felt my heart rip out too just 2 days ago when I contacted a local dealer. He was at first unsure so he contacted Hi-point and asked. Although there is an upside! Hi-point is supposed to be redesigning the comp model for later release. So hopefully it will be bigger and better. Well not really bigger but you get the idea.
On a side note he also found they are redesigning the .40 carbine and will be releasing a new .45 acp carbine. So needless to say im excited.
If you really want one, just keep your eyes on places like gunbroker, or the classifieds on this forum. If you want one bad enough you can find one. I just got my hands on one for cheap - you just have to keep your eyes open.
