Second thoughts?
If you troll the gun forums, there is probably not make that someone doesn't have real or imagined issues with.
The 22A is well-made. You need to try several brands/types of ammo to find what it shoots best (probably 40 gr standard velocity ammo.) 22A's are accurate pistols. My best 10-round groups have come with my 22A.
If you have mechanical problems, the 22A comes with the S&W life-time warranty which is excellent.
I don't think you need to worry about your pistol. Start shooting and have fun.
