I had a Masterpiece arms 45acp carbine. It was very reliable, and I had no mechanical problems. They use common grease gun magazines, and if you get the side cocking model, mounting a red dot or scope is nice.
The thread pitch on the barrel is unusual (11/16x16) so you will probably need and adapter for most suppressors.
The only problem is those suckers are HEAVY! by itself, then you add 30 rounds of 45acp. I never weighed it but it had to be well over 10 pounds.
They also have a "machine gun" chamber to ensure reliability, but it tears up brass something fierce.
