I’ve had to help a few shooters that have small hands be able to deal with the M-9 Beretta (92F series) when it was mandatory. Most of the time the solution was to shift the "handshake " grip to the right (A$$uMEing right handed). It put more wear and tear on the shooting hand as the thumb took the abuse.
You said semi auto’s as in more than one platform.
Are you shooting double stack mags?
or Full/Mid Size?
I have “paws” they are size 46DD my fingers are slightly shorter than my palms but on a good day I can palm a basketball. In shooting small (er) guns I shoot low and right as I have half a finger in the trigger guard or I can actually squeeze the trigger guard itself (I can do that on a full size 1911 frame).
If you are consistently shooting left with your given grip consider moving your front sight. The low part may be your trigger pull but I would be more inclined to think it is your ballistics. Boolets will cross the line of sight TWICE, once on the way up and once on the way down. If you are low your target is too close, if you are high your target is too far away (A$$uMEing 5 - 15 yards ish) My 3.4" Colt Officer’s Model 1911 will rip the X ring out at 7.5 yards and also be dead on at 100 yards with 230gr Match Ball ammo. My brandy new RIA blows the center out at 15 paces (~13.5 yards) and I haven’t figured out where the long line is yet I figure about 75 ish yards.
There are a few things you need to think about and I’d be happy to help you sleuth them out.
