Need recomendations for a 9mm target (not defense) semi-auto. Prefer a 5" barrel with adjustible rear sights.I allready have a variety of guns in different calibers including a 22lr. The 9mm ammo is plentiful and much less then my 40 and 45 ammo (bought from walgreens and online). The 22lr just ain't doing it for me. My son who is getting his masters in cop is moving back home broke and hoping for lots of range time on my dime.
