>>63884459 (OP)Everyone concerned with this is using a pistol dot in a non-optimal way. You should have your eye focussed on the target, and be merely aware of the dot as it crosses it. Once you do this all dot housings stop being obtrusive. What you want isn't an "unobtrusive" dot, it's a large window in which to find the dot.
You can use a target focus technique with irons but it's much harder.
>>63891266The only way to do this would be to mount the dot on the rear of the slide, this would mandate a target focus because now the gun itself occludes the target.
