So I am a broke college student with a brand new generation 3 Glock 17. I do not have much money which is a problem if what I have been told by a friend is indeed true. I have a full mag of self-defense ammo. I rack my gun, now, one is in the chamber. I refill my mag with one more self-defense round. 18+1. Nice. Well... My friend told me that with doing that eventually the bullet, the 1st and 2nd bullet, will eventually fail due to bullet compression. He says that the bullet will be pushed into the casing. If this is true is there anyway around this? I like to carry one in the chamber, I am 21, I have my whole life a head of me. I want to be ready if something happens. But if my bullets are compressed due to the excessive rotation that I put them through then that will be a bad situation, I was told the bullet can blow up in the gun. (my 1st round that is racked and my 2nd one that is put into the top of the magazine, these are constantly being cycled) I put one in chamber and take it out when I get to my house. I do not keep the gun loaded. But when I go out, one in the chamber. Is this true. Is there anyway around bullet compression? If I rack it very slowly and never take my hand off the slide and just let it ease into place is that the best that can be done? thank you. I do not want to have to buy new SD ammo continuously due to compression.
