I am not yet in the market for a Dot, but I can see it coming to replace my iron sights.
My questions are related to my particular interests, being every day carry *and* competition. I currently EDC a Glock 48 (non-MOS) and recently bought a 34.5 MOS for USPSA. My budget, per dot, is somewhere in the $300-$400 range. I plan to buy two. I know I'll have to get my G48 slide milled as well.
Insofar as priority goes, I value reliability over optional functionality. I am ok with replacing batteries to maintain dot Operational Availability, but when I draw, I really want to have confidence the dot is going to be there, pretty much all the dang time. I don't value things like being able to "switch" dot sizes or to add additional features to the sight picture, as much as I do a simple sight picture which works (all the time). I also value a robust physical design, which would stand up to normal match and carry use, much like I value the robustness of my Glocks.
With that:
Is it a consideration to chose a "dot system" in this case? (in other words, do I need to pick a Dot from the same maker for both carry and competition). If so, are there any makers which support both standard Glock slides as well as slimlines?
Is my budget achievable / realistic? In regards to my price point, are there any current manufacturers which stand out as being "the obvious" choice, for my situation?
No real urgency in my question; it's more a long term project for '21 and beyond.
