I was an idiot and got a small amount of yellow glue on (or inside) my cross stop pin. I took the barrel (slide) apart to remove the glue...now there's no spring to the pin. Is there supposed to be a spring around or below the pin? Wondering if I either lost something, or just don't understand how the mechanics of the pin are supposed to work. Regardless, it's not functional at this point, so if anyone has any ideas for a fix, let me know!
