Re: From semi-auto to auto
Has anybody tried this? Is there any technical reason why it shouldn't be done?
I haven't tried it, but I have a friend who attempted to turn a semi-automatic .22 rifle into a full automatic (yes, he's an idiot, but he's usually good whenever machines are involved). What he ended up with was a rifle that'd fire 2 rounds and then jam every single time. Judging by his lack of success I'd have to say that the process isn't as easy as you'd think.
On the other hand I have another friend (a gunsmith who actually gets paid to repair guns) who accidentally made a full auto AR-15 once by forgetting to put in a certain spring. (In case you're wondering he took it back to the shop and fixed it after the first unexpected burst.) It stands to reason that there's a significant difference between something that was engineered 'down' from full auto to be semi-auto, like an AR-15, and something that was designed as a semi-auto to begin with, like a pistol.
Plus it would have to be a very heavy but low caliber pistol for anyone but a very experienced shooter to control in full auto. You'd need something that weighed like a Desert Eagle but fired 9mm for it to actually be usable, which is about what a Micro-Uzi is.
