Mackay and others who have multiple EDC pistols. I understand that you might have a different gun for hot weather and cold weather applications. But from a tactical standpoint, thinking muscle memory here, would the best approach be to have as few platforms as possible and for those platforms to be similar? Say a Glock 19 and a Glock 48. Grip angle the same, controls in the same place, sight picture the same etc.
When I was on active duty in the Coast Guard we were carrying Beretta 92s. I started working part time as a reserve deputy for Harrison County. I went with a stainless 92 so that there was no relearning, retraining etc and muscle memory was identical. Seems like there would be similar value in being as standardized as possible with EDC.
