Colden, you are correct in that Romanian side-folders do fold towards the right, or the side with the safety lever. This, however, doesn't really make it any more difficult to operate the safety than with a standard stock, or with an underfolder for that matter. (The placement of the safety lever is one of the bigger complaints most folks have with the AK system.) The way a Romanian folder is shaped, you can operate the safety with the stock folded. All you have to do is move your hand up and extend your trigger finger until you can reach the safety lever. Then, you just slide your hand back down and squeeze the trigger.
You can also unfold the stock with your hand on the pistol grip by simply reaching your thumb back, pressing the release button with your thumb, and using your trigger finger, push the stock away from the gun and into place.
Blackjack Buffers markets an extended safety lever for the AK which alleviates the problem of not being able to operate the safety with your hand on the pistol grip. You can get their levers with or without a bolt holdback notch.
Red Star Arms sells them on their website. I have one on one of my SAR-1's and will most likely be putting them on several of my other AK's in the future.
If you do go with a folding stock of some variety, be warned, it will not be easy to direct aimed fire at anything beyond 10 feet or so, unless you extend the stock, and near impossible with one hand. I say this because you state you want a semi-auto for its' ease of operation one-handed. However, an AK with a folded stock is not a one-handed weapon, especially with a loaded magazine. With an full stock, or an extended stock, you can POSSIBLY fire shots in the general direction of your intended target with the stock held in the crook of your arm. A folding or collapsing stock on a rifle is not intended for firing with the stock in any position other than in its' extended state. The ONLY purpose of a folding/collapsing stock is to make the weapon compact while in a small area, such as a vehicle. BEFORE you go into a firefight, or immediately after contact is initiated upon you, you should extend the stock and then begin firing.
I don't think you'll find too many rifles out there with a 16" bbl AND an OAL ~ 26" with a full stock, unless you go bullpup. Heck, with a 16" bbl, that would only leave 10" for reciever AND stock. Even with a pistol caliber, which would give you a shorter reciever than a rifle caliber, you still wouldn't have enough stock to fire comfortably. If 16" bbl, 26" OAL, and semi-auto are your primary concerns, you don't have many choices. You're pretty much limited to bullpup, SBR, or some form of folding stock. Good luck on your quest.
