Whenever you have a non-fire issue, hold the gun pointed downrange a few seconds. Drop the mag and eject the cartridge in the chamber. Look at the cartridge that you ejected, and check the primer for an indentation. Since you were getting rounds to fire and others not firing, you are likely having light hits. Looking at the cartridge primer, that failed to fire, you should see a small indentation. This indicates the striker hit the primer, but not hard enough to cause ignition (bang). The primary cause of this is the ammunition. Some manufacturers use a primers that requires a more powerful (harder) hit to the primer for ignition. Most of the time if you reuse this light hit cartridge, it will fire the second time around. Seems that some manufacturers get a few harder primers in a batch of ammo, and you get some light hits. The solution is to use a different brand of ammo. I have had some guns that were subject to light hits and found the inexpensive Walmart Federal Champion ammunition fired every time and I had no light hits. I have read some people have had light hits with White Box, UMC, and others. I have had a few with CorBon High Power SD ammo. You need to try different ammo until you get one that fires each and every time.
Now if you checked the primer and there was no indentation on the primer, you had a more serious issue. The striker did not hit the primer and you need to diagnose the issue. Could be debris in the striker bore, broken or damaged striker, lock up in battery, or ?
Next time out to the range, let us know the results.
