I love mine. Mine personally is a bit picky about magazines but I think that's only my specific one because other 1911s all run my stuff just fine. I just haven't felt like dealing with sending it back to S&W to get a tiny issue resolved. It works really well anyway.
It's a damn deal. Mine with night sights and a rail was $1199. I think you should hop on it.
What I love about the S&W ones (and the Ruger ones) is that they use a series 70 style firing mechanism. There is no firing pin block. The trigger is awesome out of the box. Couldn't be more pleased.
That looks like an E series S&W. It has a MSRP of $919. Given the current supply of guns, $899 sounds like a good price. SA is known for making a solid gun, but that one seems a little overpriced for the features. OTOH, my old eyes would really prefer the higher profile sights of the S&W; the S&W's front strap checkering is nice also. If it were me, I'd prolly go for the S&W.
