I got small hands, so there's no way I can use a thumb on a standard release, so they're always right where they should be for my left index finger to sweep it.The biggest thing will be the ambidextrous slide release. Most have the reversible mag release.
I know the G****s, 5th gen for sure, maybe 4th, have the ambi slide release.
HK VP-9 is good on both. Same for the Walther PPQ. Sig P320 & the 2.0 M&P's too.
THIS.Another aspect to consider is gear, holsters in particular. Make sure you can get a good quality holster for lefty's.
