Stripped threads on small part

[zxing]

Hello everyone, I was shooting my favorite 22 pistol, a Beretta 71, when the slide release fell off. It's held on via threads by a pin, but since it will drop in right over the threads currently, I believe the threads are stripped. Anyone have any ideas on how to repair this?

The best way would be to buy new or good used parts. I would bet that would be the least expensive way in the long run as well. I am not familiar with that model but I would start with a call the Beretta. If they have the parts - great! If not maybe they can steer you in the right direction.

IMHO even if the old parts could be repaired - the better way is to replace them.

I don't know anything about that model but pins are not threaded. It's most likely a splined pin pressed into the hole in the slide release. At least that's what it looks like in the schematic/parts list at the link below.

It can be fixed; staked, soldered or loctited, but I agree with Chief38 above new parts would be best for you.

Looks like the pin doubles as the sear pin for the 76 model, part #33. And the screw in the same place on the right side of the frame must be removed to push the pin out, I don't see a new slide release listed however.

I'd try Berreta for parts.

I had a post but I deleted it after re-reading it, too confusing. I'll try this.


The pin is also the trigger pivot pin.
It is larger in dia for the length that is passes through the frame than the shouldered section that the slide stop is attached to.

The pin and the slide stop are considered one assembly/one part.
They are assembled at the factory by what ever method,,staked, Loctite, combination of.

The pin used to be silver brazed (hard soldered) to the slide stop and with the outboard end neatly riveted over for reinforcement from the outside of the slidestop onto the pin itself before furnace brazing the two together.
Here's a pic of the earlier Model 70 'Puma' slide stop that shows that assembly. Much stronger.

I don't know if these will fit the pistol in question,,I would doubt it.

The screw on the right side of the frame screws into the pin on that side and holds the assembly in the gun and from walking out of the frame.

What I would do is High Temp Silver Solder/Hard Solder the slide stop back onto the end of the pin. Clean the areas needed of course and stake it back on to hold it in position for you (must be perfectly straight).
Then a touch of Silver Solder.
Clean up and polish. It'll need re-blue as the heat from Hard soldering will destroy the bluing. But the parts will be as strong as they can be at that point.
It could be soft soldered, but with such a small contact area, I'd go ahead and Hard Solder it.
Either may leave you with a very tiny speck circle of solder showing on the outside of the slide stop where the pin comes thru. But nothing to stare at and cause you to stay awake at night.
Touch up with a cold blue like Oxpho-Blue or I would just Express Rust blue on the stove top for a good match and wearability.
