I like to tinker. Tinkering led to working on some guns. That led to "my guns locked up, can you fix it?" So I got the gun, tried racking the slide and yep, it was locked up.
After disassembling as far as I could my eyes were in disbelief. A substance had fully saturated the slide, breech and extractors, firmly locking them into the barrel extraction grooves rendering the slide tube frozen as well. It was most certainly locked up. A gently pry here and pry there led to a gun in the vice, a dowel in the barrel (fixed barrel) and a dead-blow. After the third or fourth whack it let loose, allowing me to see the extent of the goop damages.
The breech block was junk, goop had leached inside the extractors, locking them solid so it went into the trash. A dental pick and lots of solvent later, I had the receiver cleaned out. Reamed out the end of the chamber and mag tube then polished. Replaced the breech block, cleaned the slide tube rod, carrier and slide assembly then reassembled and test fired. Back to normal.
Called the guy and said "come and get it". I had to ask what the heck he did and his reply....
"I guess I used a little too much Loctite when I put the Weaver base on"
Just a tad.
Cheap beer cheers my friends, it can always get worse.
