A quick google search lead me to the browning BPS. Also if you have a spare pile of cash laying around you could grab a KSG or UTS-15 which are ambidextrous.

 

The only two pumps that come to mind is the Browning BPS and the Ithaca Model 37 which have downward ejection (as designed by John M. himself) so are truly ambidextrous.

Of course, SxS and O/U don't have that problem just not a lot of shell capacity so you have to learn the quick load if you want to use it for a P/HD gun.

 

model 37 ejects from the bottom but has the push button safety behind the trigger. The sagia might work for you or something like the 1887 lever action.

 

Looks like Mossberg

 

I'm a lefty and it's the 500 and 590 for me!

 

dstra is on the money here. Ambidextrous tang safety so everyone can shoot the thing. I'm also a lefty.

 

I have a KSG, and it is "clunky". Not like an 870 at all. Totally requires training, a lot of training. That said, I like it. Another option might be a coach gun.

 

When I was a young lad, my pop used to tell mom jokingly "this boy's a south paw! He needs one of them left handed hotdogs!" If I was about to bite one he'd say "that's a right handed hotdog! You need to turn it around and eat it from the other end." He was a good fellow.

Remington has been making lefty 870's for years. Finding one might be a tad difficile, though.

 

Im a lefty and have always had mossberg 500s. Safety works for me, as does the bolt release, one reason I didn't go with an 870.

 

With a standard style stock on an 870 I just rotate my grip slightly and use my thumb thumb to disengage the safety.

 

Thousands of us lefties learned to use the M-16 left handed. No big deal.

 

My vote is Mossberg 500/590 with a model 37 in second.

 

Hardcore lefty here.. I have Mosserg 500's and 590's.. manipulating the safety and action release are easy for us. The shell ejection to the right has never been a problem.

 

Us Leftys Must Hang Together Or We Will Certainly Hang Separately

Excellent answers already given and thanks. 1) Model 37. I have forgotten how the Model 37 safety works. 2) LH Rem 870. I think the thumb safety on the LH 870 is also reversed, if memory serves...help here. This might create safety/operation/training concerns?

3) Tang safety Mossbergs I can work OK. Have had several. All kick too hard nowadays. 4) Left Hand Rem 1100 semi auto. An older design. A Very sweet soft recoiling shotgun. I do not know about how that safety works. Been too many years ago. If I had an AR15...

...I would hold out and build another dedicated LH Stag Arms model 20" HB rifle with a ambo safety. We lefties have an AR15 operation control advantage. But over time and many many rounds, the gas port discharge becomes a vison hazard for us.

Yep...I also have no problem shooting a right hand Mossberg pump shotgun, as along as it has that ambo thumb tang safety. Never even see the ejected cases, FWIW. Good question and thank you. We must hang together or we will certainly hang separately. HB of CJ (old coot lefty)

You can buy a left handed 870 trigger assembly (w/LH safety). Not really worth it in my opinion.

Beneli makes a real nice LH semi-auto shotgun (Montefeltro & Super Black Eagle) that I drooled over for along time but never pulled the trigger. I believe the safety on the Beneli Supernova is reversible.

 

Another bonus of being lefty: the M1, M14, and Kalashnikov are all left-handed weapons! Sure, there is a right-handed manual of arms (do not waste your time with it if you are fortunate enough to be left handed) but it is nowhere near as efficient as doing it left handed. Clearly, the designers knew most people were right handed and must have intended them for right handers, but they put the operating handle on the right as if they were bolt guns. But they aren't bolt guns and they are more efficiently run left handed.

I can keep a firing grip, work the action, and throw a clip into an M1 without having to take it off my shoulder. The right hand thumb goes under the stock, and the fingers squeeze the clip home. You can run the action on a 14 while maintaining a firing grip. And all the ergonomic complaints people have about Kalashnikovs melt away if you shoot it left handed.

 

Being a southpaw myself, I would agree with the above quote.

SEI even went so far as to produce a bolt release for the M14 IOT help out right handed folks.
As it is built, a left handed guy can work the safety, op-rod handle, mag release, and magazine without ever moving the left hand from the grip.
Ejected brass should end up at the 1 to 2 Oclock position, so no issues there for lefties.
The AK is a very southpaw friendly rifle as well.

Both allow for easy transition between hands IMO.

As for shotguns, I prefer the semiautomatic Bennelli's and Berretta's.

The only thing I have done to my M121 is reverse the safety. ( Same with the 10-22)

11B

 

Ithaca and even the New Savage 350.

 

Don't forget the old Winchester 97 pump gun. Benefit of being able to hold down the trigger and have it fire as fast as you work the pump too.

 

Mossberg 590A1, a done deal and it's on order. Now for dummy rounds.

 

Remington 870 with an oversized left handed after market safety---20 bucks.
