Hi I am a fairly new gun owner and am experiencing my first malfunctions. First, off I have a used Glock 23 gen 3. It was firing great until I both made some mods and bought some reloaded "target quality" ammo. I put in a ZEV Technologies competition spring kit, a LANTAC SSR 3.5 lb connector, and a Glockstore tungsten guide rod. Initially, I had to revert back to the stock firing pin spring due to the firing pin not setting completely. After that, with the exception of learning how to be more careful with a light trigger, it was shooting fine. Then I bought this ammo cause the price was right. At first, I was only having 0-2 FTF per 200 rounds. The FTF's looked to have a light strike sometimes off to the side. Not really all that bad. I tried to test the limits of my gun and didn't clean it for 3-4 range visits. It performed the same and I ended up cleaning it. Then I didn't clean it one more time and went to the range. Well, let me tell you, the crap hit the fan. I had 6 FTFs in 91 rounds. Also 4 times the trigger pulled, and the striker released, but the bullet did not fire and there was no mark on the primer. I'm guessing it's going out of battery as the firing pin test worked. Could be a combination with crappy ammo too. I had left my ammo in the truck so it was cold, not sure if that would affect it. Well like I said I am new so any advice would be great. I gave my gun a good cleaning, including the firing pin channel which was pretty dirty. I'm itching to get back to the range to test it out.
