Maybe with different grip panels. And two .45 230 grain hardball rounds should be enough at close range.

Glazer Safety Slug
These look like Blue pencil erasers, big fat plastic coated bullets. The glaser slug is a copper cup filled with liquid teflon and lead shot, sealed with a plastic cap. When it hits the target the cut ruptures and the contents spill out. as the projectile is light it travels very fast, and when it hits it spills out and expands in a spherical shape. this allows almost perfect energy transfer and massive shock and wounds. Unfortunatly, this also means it can't penetrate any armour, and even heavy clothes or a wallet can stop it. (difficult luck roll to take trauma only) This also means it can't ricochet or shoot through any target, making it a 'Safe' round
