I want to hunt with my Glock 20 this year. I'm looking for advice on barrels, scopes and mounts. Also looking for advice on what game is practical to hunt with this handgun. the ammo is 10mm, 200 gr JHP, 1250fps, 690ft.lbs. i'm interested in deer, black bear and cougar. utah law has no requirements on barrel length anymore. as long as i'm .24 caliber or better with at least 500lbs at the muzzle and an expanding bullet, i'm good to go. but the law doesn't tell me what's a "good idea". what distances can i expect to shoot effectively with a scope?...50 meters...150 meters? should i drop in a longer barrel anyway? any info is apreciated. if you think of things i haven't mentioned feel free to speak up. also, if you know of any online or local resources (SLC, UTAH) for handgun hunting please let me know.
