i hope you ae happy with them. i had a set on a glock 19 that i used to own and they were awesome. i pefer three dot night sights for more precision shoting but to tell you the truth i was suprised by how good they through the rds into groups on several occasions. it was like i pointed the gun in the spot and bang and the rds went where i wanted them everytime, it was so easy it felt funny.
i believe they are great for cqb type applications carry and hd when shots are gonna be close in, but even if the target gets a little out there it can be hit quickly and accuratly. ihave been thinking about getting a set to put on my kahr k-40 and my xd sc .40 they are my primary carry guns and they would benifit from them i believe. on a 1911 that is just cool.
happy shooting.
