I took my G22 to the
EESA Open House this weekend, and I knew she was going to have some issues. Anyway, here is the problem/solution because anyone searching for G22 will likely come upon this thread. Make note, if you have a G22 and shoot high velocity ammo (or maybe even if you don't), you might want to do this before something breaks:
Here's what happened:
1. From using high velocity ammo (a while ago), the hammer pounded against the hammer stop pin (when the bolt blows back). After a while it broke the crappy tiny hammer stop pin (collar type pin? like a flat piece of steel rolled up then pounded in).
2. After the hammer stop pin broke the hammer would "over ####" and whack against the hammer spring rod. After a while, it bent and twisted the spring rod.
3. Sometimes it would work, sometimes it wouldn't. The hammer would get stuck "over cocked" from the twisted spring rod, so pulling the trigger wouldn't let the hammer fall. If you whacked the side of the gun to get the hammer loose, then it'd work fine for the next few shots, and then stick again.
4. Eventually the tiny pin that holds the spring rod onto the hammer sheared off, and that was the last shot she fired.
To fix it I heated up the spring rod and straightened it in a vice, removed the twist, and heat tempered it by dunking it into oil. I then hydraulically pressed an oversized stainless steel solid pin through the hammer and the spring rod. I then drilled the receiver for a larger hammer stop pin. I hydraulically pressed in a stainless steel pin three times the size of the original! She'd almost stand up to shooting .223 out of her now!
