Probably not, but his scores would likely suffer.
Look on the line at a USPSA or ICORE match and count the number of S&Ws vs Rugers (if you see any.).
Jerry Miculek is an exception to the rule (BTW, he shot Smiths long before he was sponsored by them.)
If you're going to compare the very best, the late Bob Munden could've smoked the majority of USPSA competitors with a single action.
I have no beef with Ruger when it comes to precision SA shooting. One of the most accurate revolvers I've ever owned is a RedHawk. But I've never shot it DA and even the SA trigger needed work. My OM Blackhawk .357 is still a favorite after 40 years.
95% of my shooting is DA, so I want the best action. An inconsistent pull and stack near the end are deal breakers for me. If Ruger could produce a DA pull as good as an S&W, I'd go for it, though I don't care for their aesthetics or vaunted "tank" like construction. If I want a tank, I'll buy the RC airsoft Leopard my son wants.
Oh, BTW, I buy guns to shoot, not disassemble.
