I picked one up in 4.25" 10mm. Got it home and the FAR DOT doesn't work. It looks like such a piece of junk, I don't think I will even send it in for warranty replacement. I was going to remove the flared magwell but the pin that holds it on also holds the main spring housing on. When you re -insert the pin without the magwell, the pin sticks out on both sides and digs right into the meat of your hand.
I had a TLR-7sub(1913 version) lying around that fit right on the gun. It doesn't sit all the way back onto the trigger guard, but is still far enough back to actuate with my trigger finger. Not sure if it is required to be resting on the trigger guard. Put my Holosun EPS carry on it. I was going to direct mount it to the slide but I had to use the Holosun supplied plate because the screws that came with the EPS carry were a tad bit too long. I couldn't use the screws from the FAR DOT because they are not countersunk.
I bought it on a whim and kind of wished I hadn't. I didn't realize the lower receiver is so proprietary. I figured I could change the grips to something that didn't feel so hard and plasticy, but the grips appear to be an integral part of the lower receiver. I've never really liked the way double stack 1911s felt in my hand, but this one might be thinner because it is in 10mm and it felt pretty good in the hand. Or maybe they just did it better, since I think these also come 45ACP.
I'll see how it shoots eventually. Current work schedule doesn't leave me much time to go to the range anymore.
