I sold my Glock 17 with an RMR on it that I carried AIWB for the last 6 years. I'm thinking of putting a red dot on either my P-09 or P-07, or maybe both in time. I can't say I wasn't happy with the RMR, but I like the bigger window of the DPpro, not having to take it off to change batteries (which really isn't that big of a deal), etc. The DPpro I looked at seemed to have clearer glass also, better for my aging eyes. It would also make the rear sight problem a little easier to accomplish with the rear sight attachment that can be used.
My main concern is how reliable and sturdy are they for EDC. I carry AIWB all day long everyday, doesn't matter if I'm mowing the yard, crawling under the car to work on it, leaning over a work bench or whatever. I don't do construction, oilfield work anymore so I'm not as hard on stuff as I used to be would still like something that works.
Any of you guys have experience with this optic, good or bad? What is your rear sight setup if you have one?
