I dig it too.... we have a very good SWAT officer here in town that had a ND with his Glock 22 duty gun one night (he was distracted while putting the gun on the bench, but after removing mag). He came back short stroked to get the takedown lever set, and put one through his reloading bench into his leg. All is well, and he recovered fully, but his mistake taught me to FULLY lock back the slide and VISUALLY check the chamber/magwell.... I am sure there are some high speed guys here that feel thats silly, but it is the only foolproof way with a gun that must have the trigger tripped....

OP-- breakdown while pulling the trigger may damage your gun... after 50K cycles or so.... its like dry firing.... you are not going to do it enough to see significant wear....
