It all depends.
If I am going to a really bad spot, and I have to carry alot of cash or other valuables, I'd have the glock 19 Shoulder holster + 1 mag (21x9mm) the J frame (5x.38) in OWB AND the P32 in the pocket (7x.32)
If I am just going to the bad spot with nothing much, I'd have the J frame (5x.38) in OWB AND the P32 in the pocket (7x.32)
For general self defense I'd I dont know where I'll be I'll just have the 5 shots of .38, or Just the 7 shots of .32
I figure my response to being attacked with be unique to what I have on me.
For the full set, I would try to divide evenly the glock mag for the number of perps. If I am attacked by 5 perps, I'll try for 2 hits center mass for each BG, then reload and try again. Then one each from the J frame, and then fire the 7 .32's as I run away.
All would be within 25 seconds.
If I just have the J frame, I would fire one each at the 3 most agressive looking BGs and run for cover and try to get away with 2 from cover.
Hopefully if all the stars align, after I draw, all 5 will run, and I'll shoot them in the back as they run.
KIDDING....
no shooting BGs in the back I know !
