I said...as long as it's not YOUR Clear nail polish... LOL.
Just passed what someone else here told me...so I can't take credit. I used clear nail epoxy. After a good cleaning, probably not a bad idea to reapply and let dry. I'm sure it's not impervious to gun solvents.
I even got a new trigger pin and slide lock release. Seemed to happen about 130 or so rounds down range.
When the pin is inserted correctly, you'll hear/feel it snap.
Never happened on my girls old SD9VE...but to be honest, she probably never put more than 100 down range in any one day session.
