recently purchased a G20 and a G29. been getting used to them over the last few months, but just punching holes in paper. took the 29 out yesterday. someone had a log out there around 14 inches thick. man did the 10mm destroy the log. wondered as I began how far into the log my mid range 180 grain reloads would penetrate. I am sure my mouth fell open after a couple mags when I noticed the sawdust blowing out the back of the log. I am impressed. wonder what the hot loads would do?!?! think I will make this little snot my EDC. the combination of the pistol and the round makes it a bit of a monster. carried the 20 all last week on the coast of lake Superior. I am thinking black bear would have no chance. my grandchildren will never be harmed when grampy is around. should be a good choice for both two and four legged predators.
