Mas - For the last year I have been carrying my G27 with a full mag of gold dots but a fmj round in the chamber. The main reason for this is because I dry fire a lot and therefore I'm constantly unloading/reloading a round before/after practicing. At first I used this as an opportunity to rotate the rounds in my primary mag (previously chambered round back to the bottom every time) but then it was brought to my attention that chambering a round several times causes the bullet to recede into the case. Sure enough, after several chamberings I noticed a slight overall height difference between a "new" round and a several-times-chambered round. At about $1 apiece I can't justify ruining a bunch of rounds over time. As a side note I have fired many mags with this configuration and I have never had an issue with it. My questions are - Am I an idiot? Does this potentially look bad in court? Is it a reliability issue? Am I over thinking this? Thanks in advance for your time.
