I'm new to the board and I'm sure it's been posted a thousand times, but today I went to the Smyrna Glock factory and had the most amazing experience. After checking in with the guard at the gate, he directed me to the where the armorers would be. I didn't even make it out of my car and the armorer was waiting for me with a greeting. He went over the gun ( 6 week old Glock 19 gen 4). I was there to put night sights on and asked about putting an extended slide lock lever on. I had been putting a small amount of oil on the main spring after watching several cleaning videos. He said that was bad advice. He spent 10 minutes giving me instruction on operation and cleaning techniques. He then took the gun back and 20 minutes later came back with the new sights, extended slide lock, new spring and an extra one, and a Team Glock hat. Way above and beyond what was required. He spent so much time with me, like I was the only person he had to deal with today. Out the door for $57. I was absolutely amazed at the level of customer service they provided me today. I left a real Glock company fan. I'm not sure how many armorers they had working today. I saw three performing this service. I left thinking, what great advertising this is for their company. I have to say other companies could really learn something from them. If you're any where near them, it's well worth the trip.
