Without a doubt, the only judge of what's suitable for a woman shooter is the woman herself.
The first time I took my sister (18 years old, 5' 6", and maybe 110 lbs.), to the range, I started her out with Ruger MKII .22. She did well with it and liked the weight (35 oz.), as it provided her with a steady balance in her hand. Not too heavy, not too light, and easy for her to keep it on target.
Next was a Star Model B in 9mm. (weight about 34 oz.), and again she shot fairly decent groups and didn't think the gun itself was too heavy or unwieldy, or that recoil was of any great concern.
Finally she finished up with a Browning BDA (todays SIG P-220 with a weight of 26 oz.), in .45ACP and shot her best groups of the day with it. Now you would think shooting a .45ACP in such a lighter weight pistol would be an issue for a beginner, but again no problems with felt recoil probably due to the great ergonomics of the SIG design.
