Hi all - looking to get my first .22 and could use some help. I've shot my buddy's Ruger MKIII and it was pretty nice but have no other experience with 22's. Seems there's lots of options within the Ruger lineup too so I'm a little lost (barrel lengths, thickness, saw a polymer framed one, etc). Looking for a reliable, accurate semi-auto that is around or below $300. Any suggestions?
