yeah either curl your finger under or get an extended mag with the finger grip extension.
for smaller caliber guns like a 32 or 380 its really not that big of a deal to just let your finger curl under....there isnt all that much recoil and remember, a small gun like that you are going to be shooting up close and personal probably so whatever accuracy loss there is by not being able to grip it 100% properly i would guess is very small.
i have the sig 938...i can shoot it without the pinky extension but its not ideal, i put the extensions on my mags for that one.
