I have wanted a PCC in 45ACP for close to 10 years. The problem I have run into is all candidates have been expensive, junk, heavy, or all of the above. I have a Beretta CX4 in 9mm, it has been a good gun but I paid too much for it. I have looked at the current offerings in 45ACP and here's what I have come up with.
Kriss- Probably a great unit but its ugly as hell and quite expensive at $1200 plus
JRC- When they were first released they had function issues. When I handled one I was underwhelmed with the quality of construction. I just cant bring myself to pay $700 plus for it.
Auto Ords new lightweight Thompson M1C- At 10.5 pounds it's hardly light. Once again $700 plus dollars and the mags are really expensive too. Poor optics mounting options too.
AR Platform- There are several out there but I haven't heard a whole lot positive on any of them. In all likelihood you drop 1k on one of these and have to work the kinks out. Just not feeling the love.
Beretta CX4 8045 configuration- This would be a good choice as I own the pistol and already have mags. Unfortunately they are out of production, somewhat hard to find and expensive.
Hi-Point Carbine- Ugly but cheap. My research finds very few problems with them and they seem fairly accurate as well as reliable. I can get a 1911 mag catch for $30 and use my 1911 mags in it. I just don't know if I can bring myself to buy one.
Your mission- Talk me out of buying a Hi-point carbine in 45ACP. Tell me the tales of horror.
