Alleydude: Sir; for safety; double check; triple check. Who loaded that Mag.
If the missee'alleydude loaded it.
Don't yell at her; all three of us are learning
Get her to load some while you and she are sitting about. See her make it load 11. Don't force her just follow along with a grin.
My reason for making a bigger deal than needs to be;
We know it only hold 10; so we shoot 10 and carry around a very very live dangerous firearm.
Knowledge is your mine hers them and those only safety.
