The striker on my 23 has won out.  At the range I started getting light primer hits.  I also have a 27.  All the rounds went off in the 27.  When I got home I measured the strikers and the 23 striker is 4-5 thousand shorter than the 27s. It is also round off.  I call Glock and they said a Glock armorer could get one sent to them, or I could send it in, but pay the shipping.

Does anyone have any experience with aftermarket strikers (Lone Wolf , Johnny Glock etc.)? It seems all the 9/40s use the same striker.
Thanks for any help.

Technically the 23 and 19 strikers are different.  But you can use a 19 in a 23.

a 23 in a 19 requires some "fitting"

Midway has OEM 23 strikers for $30

Damn good pricing since most places charge around $50 for OEM Gen3 strikers.

Thank you for the information.  I would rather stay with factory parts anyhow.  Guess I just started think the cheap way out.  I could just send it in but I have already replaced all the springs not to long ago.  Thanks again.

You are better off sticking with an OEM Glock firing pin. There was issues about 3-4 years ago with Lone Wolf firing pins breaking. This was mostly with their G21 firing pins but it effected their other firing pins too.

That is the answer.

Thank you everyone.  I have decided just to return it to Glock.  An FFL I know will ship it for me for 25.00.  I figure let them give it the once over. Once again Thank you everyone.
