Just what the subject says -- My Sig P239 is worrying me a little because with the breech closed, I can see the end of the round that is in the firing position. Is this normal? I began noticing it when I went shooting with my friend near dusk and he shot my gun and said that he saw "sparks" when firing it. So after that I paid attention when I was firing it. As I fired it I noticed a 'flash' of light coming out of the breech area. After some thought I realized, well, it WAS dusk when I saw the 'flash' (my friend described as "sparks"). And the force of the blast is SUPPOSED to open the breech so the shell comes out, etc. So I'm not worried about the flash I saw. However, that is when I noticed a small gap at the rear end of the breech, even when it is supposedly entirely closed. And like I said, if a round is in the chamber, through the gap I can actually SEE the round, even when it is cocked and ready to fire. Is this normal?
