Modern adjustable sights are actually fairly robust, though not to the same degree as fixed sights. I've carried Colts with Bomar-style sights and used them at multiple training classes and they were never a problem. Colt rounds the corners on theirs and I prefer that over sharp corners so yeah rounding those off a bit might be a good idea.
