Someone will contradict me

@300CALMAN,

From memory, the Sterling L2A3 9mm SMG (WW2 Patchett SMG derivative) fired from an open bolt. And it was required to be able to hit within a 10 cm circle at 200 metres, obviously in semi-auto mode. That is <2 MOA. This is not super accuracy, but it is superlative accuracy in a 9mm SMG. About as much as anyone should ever hope to get out of the 9x19mm. Someone please correct me.

Interesting, I thought it was a square foot at 100 yards, I have heard some comments to the effect that some 9mm pistols were considered quite accurate. Like the Luger, unfortunately it was apparently made with tight tolerances and struggled with eastern front conditions.

@300CALMAN, you are correct of course. Wikipedia states the requirement as "...sufficiently accurate to allow five consecutive shots (fired in semi-automatic mode) to be placed inside a one-foot-square target at a distance of 100 yd (91 m)." Still impressive for an open-bolt firer. Wonder how good an MP5 would do?

The K and baby Ks I played with were very accurate. Especially the SD versions.

The fellas that carried them for their role were scary fast and accurate with them.

Roller locking and fluted chambers iirc.
The L2 sterling smg was a pig of a thing.
I prefered the Aussie version of smg.

Never fired any of the above mentioned SMGs but had a play with them. Maybe it's because i a lefty but I thought the Sten handled better then the Stirling. MP5s are a work of art with more than a passing resemblance to a STG44.

Via the G3, you really see the Sturmgewehr-44 / StGw-44 resemblance there, especially with the older, wooden stocked G3.

StGw-44:

CEAM Modele 1950 (french manufactured gun, derived from StGw44, by emigrated German designer:

And the H&K G3:

With pleasure.

The Sterling Patchett Mk5 Silenced SMG (L34A1) was, according to Sterling, even more accurate than the standard Mk4.

The silenced Mk5s had to group a maximum of 2.5 x 2.5 inches at 100 feet and 7.5 x 7.5 inches at 100 yards. With standard ammo.

I really doubt that the standard Mk4 guns would have to group about half that at 200 metres.
