Magtech is from Brazil. Their parent company bought the Czech ammo company, Sellier & Bellot, a few years back. Good ammo. One thing, some of the ammo may be copper washed, light steel jacketed. A certain indoor range that uses magnets to test ammo will not allow it but the ammo is good stuff.
Certain guns fit certain models. For example a SIG P226 and a S&W M&P Pro use the same holster. A CZ-75 also uses that same holster. The Glock 17, 20, 21 and 22 use that same holster as well.
At first sight the 9mm house gun becomes irrelevant as does the AR. My next thought would be, where are the slugs and the shotgun.
Nice bear. Glad he didn't try entering the house.
A trained instructor should notice issues with grip. Fixing it now is easier than in 30 years. Same goes for stance and any other facet of shooting. Also since there is no family history, the instructor can be as blunt or honest as they need to be without causing issues at Aunt Marge's birthday...
