I am looking to put some new sights on my 23. I was looking at Meprolights, more specificly the ones made for the subcompacts where the rear sits a bit further back to give you a slightly longer sight radious. I was wondering if it would give you a longer sight radious on the subcom then it would do the same on the compact. Has anyone tried these sights on a 19, 23, 33, ect?? Or does anyone have any input as to why they would / wouldn't work?
