While I am new to the 10mm round, Glocks, and GT in general I can't help but notice some people telling me my G20 10mm is overkill and that I should have bought a nine or .40. I have even heard some things about a fellow named Fish who was supposedly sent to jail for using a 10mm for SD. Forgive me if this is a dumb rookie question, but is their a risk in using a 10mm for home/self defense? Wanna kill these ads? We can help!
