Vehicles, yes. Weapons, no, not really — the only poor weapon the Italians had was the Breda model 30 light machine gun. Everything else was at least on a par with that of their allies and opponents, or even of higher quality (Beretta model 38 SMGs for example).

Part of the problem appears to be the low opinion that both the Germans and the British had of the Italians, which appears to have been largely because the rank and file didn't feel much like fighting a war out in the desert for no obvious reasons.

Another reason for the bad reputation of Italian weapons of the war seems to be a misunderstanding of those weapons and their intended use. According to some modern historians, what was actually going on is that the Italian army was ahead of its time by recognising the uselessness of having rifles capable of hitting man-sized targets at a kilometre away. This is why they went to carbines as the main infantry weapon, many with fixed sights set for 200 m (off the top of my head) because that's a much more realistic combat range and it simplifies training a lot. Of course, then they went and fought a war in one of the few places in the world where having sights with markings out to 2 km may actually be useful …
