Well I don't have one to sell but I can give you my opinion. The High point has a great reputation for such a low cost firearm and I do plan to get one of the new one in .45 when I get the chance just to play with. I currently do own a Kel Tek that has performed perfectly for me. Mine accepts glock magazines of which I have plenty and can easily find more. The customer service is great and there are a bunch of options available to upgrade a little. The stock extender is worth the money and adds no lenght to the folded gun. The extra magazine carrier that attaches to the stock looks cool but gets in the way of a goos grip so I don't reccomend it. I also installed a foam sleeve that goes over the stock tube that really helps with your cheek rest.
I have handled the Kel Tec and the Highpoint. Both functioned flawlessly for me. Although the Kel tec Sub 2000 did have a breakage and I have never heard of any of the Highpoint carbines breaking. I would think that the 45 ACP versions would be a potent defense weapon at close range, but I am already set up to reload 9mm so that is what I am looking for today. Still, I wouldn’t refuse a 45 ACP version either if it became available!
What does "gauge" mean anyway? As used here gauge means the number of round lead balls the same diameter as the inside of the barrel (aka the bore) that it would take to weigh one pound. It takes 12 lead balls the same diameter as a 12 gauge barrel to weigh a pound. The smaller 20 gauge would require 20 balls of that barrel diameter. The larger bore 12 gauge would require 12 lead balls of the bore diameter to weigh one pound.
In general the number of pellets in a shotgun shell...
