People keep saying that you need some monster caliber for protection...
Maybe not.
Look at your gun: it is designed for only one thing - concealed carry. Small, limited rounds, and light weight. This is no long range shooter;it's meant for up-close and very personal.
A .32 is a marginal caliber, better than a .22 or .25 perhaps,but it will do the job.
Spend a few dollars and let a competent gunsmith look it over - if it checks out, enjoy.
