I don't have any first-hand with KelTec, (but I did mean KelTec above where I referenced the Grendel......showing my age).
One of my USMC brothers is a LEO in WV. He was telling me he carries a Glock 21 for a primary, and a KelTec P11 for a backup. He likes the P11.
Give her the Glock 21.
Well if she wanted it I would give it to her for sure, Pistols can be replaced but no way I could replace my Mom.
