Yes, I'm a lefty and shoot lefty.
I am comfortable using my index finger, but with more and more striker fired pistols having ambidextrous controls I have been converting.
Mag releases can be compressed with your grip on some pistols. That is why I like to switch them.
I know that you can shave off the release to make it less likely.
My G20 gen5- I switched the magazine release and like the ambidextrous slide release.
My Kimber R7 has ambidextrous slide and magazine releases.
My XDM compact has ambidextrous magazine release. The new models have both mag and slide releases.
I wish I could switch my LCPII release. I have turned it into a single shot by hitting the release.... I think the LCP MAX can be switched?
I've only had a magazine drop on 1 pistol I own, a S&W SD9VE. It's not a primary carry gun and I think a metal mag release would solve that problem.
But if you like em ambi - go for it.
