Hi, as in like using a Marlin then no, you don't have to squeeze the lever up to fire it.
Nope, the top mounted safety doesn't get in the way but it is kinda ugly. Lots of people get rid of them.
92's are design for short cartridges so the throw is short as compared to a full length like in a Marlin 336.
It's an okay, fun little thing. I have used it one hand and did pretty good as it is small (short may be a better term). I've changed mine some with Steves rear fold down buckhorn and front bead sight. I wanted to put on a tang rear, which I did, Marbles, but as the rear didn't fold down it kind of was in the way. I wanted the tang for long shots like out to 125 yards but wanted the buckhorn for quick pick-ups, close in. As for accuracy, expect the usual good enough to hunt with poa, poi that levers have. The esthetics are fine for the money. The fit and finish are good on mine and I do have some decent grains in the wood but not even close to the level of my JM's Walnut. The receiver is very strong and is the same used all the way up to their 454 cas. I got it as a companion to my 686 and for that its fine. It is ideal for a camp gun or pack rifle. I have a shoulder scabbard that fits it nicely. Don't even notice it. Not that it's in my needs but it would also make an ideal trunk gun. No magazines or tube feeding to fumble with, self contained, top off on the fly and really doesn't cause so much as a second glance vs an AK or AR. Cheap enough were you won't get dusty eyes when it gets a ding.
My action is pretty smooth but it was a bit rough, like all my others, at first. With levers, first thing I do is give them a really good cleaning and lube. Second thing I do is put on a shooting glove (Only ones I wear shooting gloves for are levers, wears on the back of my hand) put on the tube and throw it a couple thousand times. Smooths out the action a lot.
