I installed the XS Big Dot on my Ruger KLCR about 6months ago, and love them. Actually, my accuracy increased after finding out to "cut the Big Dot in half" with the rear sights (not the actual correct rear sight for BD) COVER the intended target with the BD, and, Bingo!, dead on. The ammo one uses also may play a part in accuracy and POI. Take care. Also, found no difference as far as "snagging" or holster draw impeding with the XS BD.
