this is all anecdotal, and relates to quite early models... when I first started shooting IPSC (pre USPSA) .45acp was the choice, and a friend obtained one of the SiG/Browning (P220?) pistols... held together with roll pins and with an unfavorable currency exchange rate, pretty expensive... the rails showed peening very quickly... produced a bad taste... when the real CZ75's started showing up in the States they were still quite unobtanium in Florida, so I picked up a Tanfoglio TZ 75 clone...it felt good, but when I range tested it, I used some hand load lead bullets and got poor accuracy out of it... not the gun's fault, but again a bad taste...I was comparing it to a single action P35 Browning I had that was very accurate shooting .357 dia 38 super bullets, so it went away... when I got my first Glock Gen1, one of the top shooters in the state was on the Miami PD and did a whole series of tests prior to them adopting the platform... I was impressed with his recommendation, even though the pistol was not a 1911... it was a safe queen... poor sights, weird trigger, plastic grip etc...when I started shooting 3 gun pretty seriously I started evaluating my choice of firearms... exchanged the 1100 for the Benelli, replaced the Holosight with a good optical sight, and the final straw was when I broke a 1911 barrel link in 2005 (60,000 rounds, but it had to break at Ft Benning ) I then switched to the Glock platform for competition pistols as well as carry pistols... I eat dinner with a good friend that is a pistol smith every week, and a couple of weeks ago, he was working on a SiG...just a lot of little springs to operate levers... I think the Sig engineers are a family relation to the S&W engineers that love little springs...
I've switched my optics preference to Holosun... I think they have an excellent product for a couple hundred less than Trijicon... a 507c for the M41, and a 510c for the 10/22
