I have a Beretta Neos that fires what ever ammo I put in it flawlessly. My one gripe is that the 2 roll pins used to hold the sight in drift out as I fire. If it happened once every hundred rounds or so it wouldn't be a huge issue but having the pin drift out a full quarter inch each magazine is really getting old. Does anyone else have a similar issue or a possible solution?

I have that same problem on my Ruger MarkIII rear site. I hesitate to spread, or try to spread, the pin to make it tighter because I don't want it stuck or bent. What I was planning on doing is useing a very small amount of removable locktight on it when it's out and pushing it in. I think the consistancy of that stuff ends up being rubbery plastic when it dries and should hold it in, yet still be easily removed with a pin punch. I'm curious what else people come up with besides getting a larger diameter pin.

Yep, I'd try a dab of blue loc-tite on the end of the pin.

I tried the Blue locktite today after prepping the are with brake cleaner and alcohol. The locktite bond broke in under 50 rounds. I suspect that the smooth pin and smooth hole might not offer enough grip

You need to let it dry for 24 hrs. The only reason it wouldn't work is if the pin and hole are not spec'ed correctly. Just for reference the whole purpose of loc-tite is for smooth surfaces. You can try an activator if its not curing properly, but its usually not necessary.

this was the second time with the blue locktite. I tried it a few weeks ago and let it sit 5 days days and it still didnt hold.

At this point I'd recommend getting in touch with Beretta to see what they can do for you.

For anyone with roll-pin problems I would first get a new roll-pin and see how that works for you, over time with R&R'ing them they will size down, remember it's a clearance fit. As far as locktite, if you really need to go that direction I would use something along the lines of Purple, very light strength before using blue. You don't want to locking it in too bad where you need to apply heat to remove unless the heat from shooting was going to be enough and you were going to take it apart immediately after.

 

Another thing is if you have a machine shop supply house they can measure the hole and give you the proper size to replace it. Most product specific parts cost 10 times what they actually cost just because, so supply house contacts can be very good to your wallet and most places if you were looking for 1 or 2 would probably tell you to just take them and have a nice day.

On this it could be the type of thread locker you are using, you need to use one that is good for the surfaces you are trying to hold together. This can get problematic with normal house hold locktite you have if it a metal plastic bond. Another thing is all surfaces need to be clean and dry. I know all basic info but just want to bring it back to basics just in case it was missed.
