I have recently gotten interested in the G20 and have been thinking about purchasing one. So, I have been reading some about different ammo for different situations. I am curious what you would recommend for 2 different situations. For self defense ammo I would want something that expands and is not known to penetrate too much or over penetrate but still shoots a flat trajectory and is effective. For woods carry ammo for hiking and backpacking I would want something that has a lot of penetration and power suitable for larger animals one might encounter. What might you guys recommend I look into? Or... what would you use?
