So you do realize that the P365 is also a very popular choice for women, right? Of course there are also extended mags for the Ruger, theres extended mags for just about everything. The point is the 1.5 stack allows for more capacity in a tiny form factor.
Keep in mind that the 12 round mag isn't even an extension, thats standard, it comes with the P365 when you buy it, its just long enough to have a pinky rest and thats it, otherwise if you are comfortable with only two fingers on the grip you can go with the flush 10-round.
And no, the LC9 doesn't carry all that differently than the P365 (at least the original smaller 3.1" barrel version, that is) and thats why people like it, men and women alike.
And of course these days there is plenty of competition. The Springfield Hellcat and S&W Shield Plus are just the two most popular alternatives. They also use 1.5 stack magazines.
You see the P365 and other 1.5 stack handguns dont carry much differently than the LC9 for a simple reason - the thickness of the slide. The LC9 has a thickness around 1" just like the P365. So sig took a look at that and said "why don't we make the grip the same thickness" and then the 1.5 stack was essentially born.
Here, I pulled up dimensions so you can see just how close the P365 really gets to the LC9:
LC9: OAL 6", thickness 0.9", Height 4.5", weight 17.2 ounces. 6-Round Capacity.
P365: OAL 5.8", thickness 1.0", height 4.3", weight 17.8 ounces. 10-Round Capacity.
Bonus: P365-XL Specs:
OAL 6.6", Thickness 1.1", Height 4.8", weight 20.7 ounces. Of course this has the longer 3.7" barrel and flush mag is 12-round instead of 10.
But the LC9 flush mag is 6 rounds, the P365 flush mag is 10 rounds. Hmmm, starting to sound an awful lot like 30 Super Carry, isn't it? Except these are all 9mm handguns.
The P365-XL is in a size category that is completely unique. Its larger than a micro-compact single stack, yet smaller than a traditional double-stack Sub-Compact like my original CCW - the Walther PPQ Sub-Compact LE Edition 3.5" barrel. Some competitors have joined like Springfields Hellcat PRO but they are few and far between and don't shoot as well nor have as many features.
Perhaps this will finally get the point across. Here is a link to the specs:
