Mudder...I'm thankful that my eyes are still relatively good for anything beyond 3 ft. So using the open sights on my pistols are not a problem. The reason I purchased the Venom for my Shield was because I am going to be assuming the security responsibilities at my church and, should the unfortunate need arise, to make a precise shot without injuring innocents.
I couldn't get use to it and a delay in picking up the red dot could result in a tragedy.
