Red line in the barrel of new glock 26, is this normal?
Hi all, totally new here but glad I found this forum. I bought a glock 26 several weeks ago and recently fired it for the first time at the range. The only ammo I had with me was some armscor FMJ 147 grain subsonic. Over half of the rounds were keyholing. I wish I would of had time to try some different ammo. What I'm really concerned about is this red/orange line inside the barrel. Is this type of wear normal? I've only put 30 rounds through the gun so far and it was all that armscor ammo. Pics are below, if anyone can offer some insight or advice I really appreciate it!
