Real issue with getting a STEN- any STEN- to shoot is usually the magazines. The "Plumber's Nightmare" can be a bit of a hassle.
Re: Re-enactors- and apologies for highjacking- friend was having dinner with his wife- was wearing Second Virginia belt buckle (oldest unit of the US Army, lineage goes back to Bacon's Rebellion) Lady noticed the buckle, asked if he was with the 2nd VA. Dave proudly told her that he had just become the Battalion Commander that week.
Lady looked upset, replied that HER husband was the battalion commander.
After a minute- it sunk in. Dave's wife asked the lady- "Your husband is a re-enactor, isn't he?" Well...... of course!" "Well, my husband is the battalion commander of the ACTUAL Second Virginia. They still exist, y'know."
