Pin & Weld Issue

[Worsley]

I am in a bit of a pickle here. I sent off my 9mm barrel to get pinned and welded and learned I should not have bought one with 1/2x28 threads. The business I used was very courteous and shared their concern that with only 1.73mm of material there, they were afraid they’ll either blow through the barrel or not get it deep enough so they’re sending the barrel back.

I really appreciated their integrity, my concern is what do I do now? Is there another method where I can attach the muzzle device without pinning and welding it? And if yes, who does it?

1/2x28 is the most common doubt you would have found a different thread pattern good news is here’s the other options.

Permanent methods of attachment include full-fusion gas or electric steel-seam welding, high-temperature (1100°F) silver soldering, or blind pinning with the pin head welded over.​

Ref: ATF 5320-8 ATF National Firearms Act Handbook, pg. 5.​

They were mistaken, but at least they didn't mess your barrel up by doing something they didn't know how to do.

Clandestine is absolutely correct. The shop is wrong. Blind pinning a 9mm barrel is doable. Even with 1/2-28 threads.

Thank you, any recommendations on where to take it?

That does seem thin, I wonder if their "mic" was off.

Wilson has been getting shit on a lot in the clone rifle groups I follow on Facebook lately. I needed an AR barrel pinned and welded and went to John Thomas but I think he only does AR work.

I will measure the thickness when I receive the barrel.

My apologies, but I no longer make recommendations.

I can't control the quality of someone elses work, and people in the past have tried to hold me responsible when the work is bad.

Class 3 won't do pin and weld anymore. I've used him foe threading and he is damned good. Said the weld work was too slow for him anymore.

That's a shame, his pin & weld was very tidy. Textbook work.

Can you at least make a recommendation on how I can get my signature block as long as yours?

In regards to what? I've used him for a couple of jobs and was happy with the work.

A sense of humor is under rated these days.
