Bearing in mind that this is just my very own personal opinion I'd pass on the 40. To me its the same reason as your 357 J frame, some brutal muzzle flip. It's tolerable, some even enjoy it, I used to back in the day.
I have a K40, had it magna ported and still too much flip, again I can shoot it without pain, even a lot of rounds but just not fun for me anymore.
The plus side of 40 is everyone seems to be walking away from it so if there's another ammo crunch 40 will probably be available.
I love 40 in a full size gun and I got along fine with it in a Glock 27 but if I was looking for a PM I'd go the 9 and everyone knows I'm not a 9 guy but I seem to gravitating to it more and more, probably from hanging around you guys on this forum.
But I ain't carrying no 380, no way, no how. And nothing in my pocket neither.
Ok see what you done, you pushed my buttons and got me all worked up........................
I'm better now, I'm sure others will be along and dispute what I've just said and that's perfectly ok too.
Be nice to find one you could shoot but that might be a challenge too.
