I own an IWI Galil Ace Pistol, GEN 2, 7.62 x 39. Fired about 3500 rounds to date, using WOLF Steel Case Ammo, some with, some without the LACQUER finish on the cartridges. Last week, experienced (for 1st time) some "failure to extract" issues. Removed buildup of crap under the extractor claw, but wanted to disassemble bolt and clean inside and the parts. Found out (info NOT in manual) that firing pin has a SPRING which prevents it from "floating", so disassembly, per a somewhat knowledgeable forum member requires "small but VERY high quality punch, good bench block and sturdy workbench, as I will need to give firing pin retaining pin a significant WHACK (not tap) with hammer to remove it, AND, will need to make provision to prevent launching of SPRING holding firing pin in place. I've serviced regular AK bolts, but not this kind. Anybody done this yet ? If so, any tips, specific tool recos, etc., welcome. I am no doubt a gun nerd, I like to take care of the few firearms I have, and I like to know how to properly do it. That apparently makes me a target for some who think reading a manual is heresy. So please, if you're one of those, don't reply. Thanks
