Thanks for the welcome.
Steve, i saw John at the store today & he informed me about the forum.
I was not even aware of its existance.
I have been working on an AK47 where the firing pin made very light contact with the primer & occasionally would misfire.
I believe i have fixed that problem with a longer firing pin so the hammer will provide a deeper penatration into the primer.
I do have a Makarov 9mm to sell, so this site will be great. Bill
