SWD M11/9 SMG cracked upper

It could be repaired, I’d use a TIG welder for the job.

Yep, TIG repair.

If not dimensionally or aesthetically precluded, a reinforcement seems like a good idea.

I had the same thing happen with mine, but it was back in the 80's and they were still making guns and parts were readily available. I went the replacement route, as they were cheap (around $50) and it was easy.

I found out pretty quick the M11/9mm's were OK with standard velocity ammo, but the hotter SMG stuff wasnt good for them. What you see above happened with some surplus SMG 9mm that was readily available at the time, and it took less than a case to do it.

The first thing to go was the charging knob sheared off, and the way the gun ran should probably been an indicator that things might have been a bit to warm. It ran a good bit quicker and you really felt it in your cheek through the stock arm.



I stopped using the hotter ammo with the replacement and got another 30 years out of the gun without any problems before I sold it.

You tried these guys?

I came across this today, and seems like it had your name on it.
