More than once law enforcement officer has been killed because he accidentally hit his mag release during a shootout. And those are regularly trained professionals
I've seen this happen more than once during IPSC matches as well- its funny when it happens there though.
t takes a lot of modification to get a super-accurate revolver.
Not really.... It takes a lot more to accurize a semiauto, wheelguns tend to be much more accurate right out of the box. Its the whole magazine capacity issue that limits their use in competion. Colt and S&W .38 specials used to be the preferred bullseye pistols at one time, The only thing they give up to a highly tuned and fitted semiauto is the lack of fast reloads during rapid fire stages of bullseye matches.
