Agree 100%The quintessential win/win situation. I own both and IMHO you can't go wrong with either one.
I run Tarrin Tactical +2 round extensions on my G43 to get past the short grip issue.
I have both an LC9S Pro & a G43. I shoot the 43 better & there are a LOT more aftermarket things for it (sights, holsters, etc.). I like both of them, though.
G43 or LCS9/Pro
Throw in the M&P Shield and I face exactly the same conundrum. Whichever of these I happen to be fondling at the moment feels really good in my hand. Bascially, too many good choices has led to gridlock on my part. Yep, I over analyze purchases, it's what I do.
I wish there were someplace in the Evansville area that rented these guns so I could shoot all three. No joy so far.
