Thanks for the info , but after looking at a ton of pictures and measuring the rear sight (.147 with my calipers) I noticed in all pictures and looking real close at the front sight I could see where the original was and now I can see the front sight has been changed as it doesn't even look close to anything I've seen and measures .310" and the original is .180" and that is really close to the amount I was having to raise the rear sight to still shoot low , so I'm going to leave the rear as is and ordered the factory original and I should be good to go . Again thanks for the reply .
