My brother had one and I got it from him.
It's very reliable and looks like it came throated from the factory. The first time I shot it he and I put about 60 rounds of assorted .45 ammo, including SWC target reloads, through it. It fed everything.
The only problem I've had with it is one of my .45 magazines will not seat.
I had a bad afternoon at an IDPA match once too. I had to borrow a mag since I'd forgotten most of mine and had a bunch of failures to feed. With good mags, no problems.
My youngest son likes it and used it in a steel plate match last year.
He beat his old man who was using a 9mm BHP.
