My 1911 Pro Series in 9mm has been flawless. Not only does it go bang every time, it is one of the most accurate guns I own. The only issue I had was the size of the grips was not allowing for the firing pin safety to disengage. That was easily remedied.
I have had a custom 9mm 1911 before. The recoil level is pretty low. I have seen the S&W one too, and have been tempted.
I do like 9mm. One negative I considered was the magazine capacity for such a large gun, compared to non 1911 9mm handguns of the same size. I can carry 15-17+ in my Beretta 92, over the 9-10 rounds in a 9mm 1911. But, if you are a 1911 fan, I think you will be pleased
I think the only difference between a 9mm 1911 and a Super 38 (38 Super) 1911 is the magazine, barrel, and recoil spring. I used to run a Wilson Combat Super Grade Accucomp LE (named after Letham-Enos) in 38 Super back in the day, 1980's, when a single stack 1911 in 38 Super was the hot setup for IPSC/USPSA. Finished 21st at the Nationals one year with it too. Of course there were only about 450 competitors that year.
