Welcome to THR.
I would first suggest doing a search here on THR in regard to training the brain first.
NRA classes, Classes near you held by training facilities that do new shooters introductions.
Books such as those by Ayoob, Givens, Gila Hayes for starters.
There is more to Reponsible Firearm Ownership - than Firearms.
Educate the brain, then be brutally honest with yourself, if after reading you want to continue...
With another lady that is a seasoned shooter, or better yet an Instuctor, Range Officer, Safety Officer, etc. Talk with them, again listen and be brutally honest with yourself.
From there ask this person to go with you, and let you try a variety of guns.
If you still wish to continue, get training of the brain , body and mental, using a gun that fits YOU.
AS a rule, and what I did, the gun was more or less the last matter addressed, other than gun safety , the other matters came first, then the gun. Reality check on what all this fiream bit is about, including LEGAL.
Yes , we have had folks , men and women, state " I need to think this thru before I continue" , we had some say "we are not ready at this time for a personal firearm" - we had one or two when it came time for CCW, WE did not sign off on, their attitude (brain) was not condusive to CCW or firearms period. We were brutually honest too. We had to be Responsible in our actions as well.
J- frames and small semis - IMO are NOT the best guns to learn on.
.22 caliber wheelguns, then semiautos. Then I/we went to Medium frame Revolvers and 9mm semi autos. WE had a variety of Guns, in various platforms, calibers. We even had Six model 10s alike - except for stocks...same gun feels and shoot different for differnt folks.
Gets into Gun Fit I and others harp about.
Crawl before you walk, walk before you run.
Best of luck,
Steve
