FWIW:
I AM a lefty.
I carry a Ruger LC9 in a iwb holster.
Some people have issues with the "safety" aspects of the Ruger LC9 (mag disconnect/raised loaded indicator/external safety, left side only).
I don't.
I actually like the little raised "chamber loaded indicator, and the safety, BY DESIGN, is difficult to put on, or off..
I leave it off, all the time..
I've had a pile of pistols, some with mag disconnect, some without, never gave a thought about it being a positive or negative factor either way. I don't carry a back up magazine and the mag in the LC9 fits firmly, so my gun always has a full mag in the mag well, and one in the chamber.
The LC9, again by design, has a lonnng trigger pull. No problem, all of my snubbys have a long trigger pull.. The long trigger pull just assures me I'm not going to fire the pistol unless I really mean to..
A safety factor to my mind.
I have a very nice HK P2000sk lacking the "controversial" safety factors of the Ruger LC9, but I can conceal carry the LC9 so much easier than the fine sk that the sk stays in the gun safe, and the LC9 makes the trips.
I've found the LC9 to be surprisingly accurate at any reasonable self defense distance (for me 7 yards)..
Just another option.
No offense, and if you disagree with my thinking, you might be right. Either way I'm too old to argue about it.
Best Wishes,
