I have a carried my Gen 1 Shield 9 since they forst came out. It has served me very well over the years. I have an M2.0 9 Shield and 45 as well. I have tried carrying several other guns over the years and the Shield just works best for me. I really prefer DA/SA, but there just isnt anything out there that works better than a Shield for me. I will check out the Shield plus for sure.
