I am considering my first Hi Point purchase. I am going to start with a carbine. It will be either the 9 mm or the 45. I have fired other weapons of both calibers and I really don't have a preference toward either caliber. Sooner or later, I will buy a Hi Point pistol in the same caliber. The weapons will be used for shooting contests with my son, target practice, and be around the house "just in case". I started out favoring the 9 mm, but here are a couple of things that are pushing me toward the 45. 1. The magazines of the 45 carbine and pistol are interchangeable. 2. There seem to be more problems with the 9 mm pistol than the 45. (Just from reading the board over the past couple of months) 3. The new Federal aluminum ammo has greatly reduced the price difference between 9 mm and 45. I would appreciate any comments to help me make a decision, especially, if any of the above statements are incorrect. I know that one answer is to buy one of everything, but I am trying hard to avoid that solution. Thanks for any input.
