I noticed while disassembling my 870 that the locking block fell out. I know that it shouldn't and on closer inpection noticed a hole in the side of the locking block. After consulting a parts diagram I found that the locking block stud was missing. I ordered one and have it in hand. My question is does it just push it into the hole (it does fit fairly snugly) or should I use loctite or anythig else to hold it in? Any advice from someone with knowledge would be appreciated. I do realize that in order to reinstall the locking block after the new stud is in that I will have to remove the firing pin and install it from the bottom of the breech bolt.

The stud is usually a roll or tension pin that's a tight fit and shouldn't need anything other then carefully tapping it into the hole.
If you're a belt and suspenders type guy, put a drop of Loctite Red in the hole first.
Use either a brass hammer or hold a piece of brass over the end of the pin as you tap it in to prevent damaging the end of the pin.
Wipe off any excess Loctite and allow to cure 24 hours. After curing, scrub the part with hot soapy water to clean off any uncured Loctite, lube it to prevent rust and reassemble.

Thanks for the answer. The stud I bought from Numrich fits very loosely in the locking block. In the last post I said it fit snuly but I had it in backwards and could not assemble it as clearances were off. It fits loosely (actually sloppy) the right way and once the locking block is assembled in the carrier it cannot fall out due to tight clearance. The gun seems to lock fine and I test fired 3 primers ok. I am still a little skeptical though.

Buying an entire new locking block is sort of over-kill.
A cheaper way is to just use what Remington uses which is nothing more than a roll or tension pin.
Buy one from the hardware store and tap it into place. Cut and file it to length.
To get fancy you could use a short piece of drill rod that's a tight fit.
