You’re probably going to have to assemble and disassemble it for her. They don’t come apart easily!!
The quality of newer S&W’s is quite good. S&W’s going back to the mid 1990’s and earlier are really hit and miss.
Just a suggestion - she might also want to look at the Sig P239, which is maybe a smidgen larger but, IMHO, is better than the Ladysmith.
