Been interested in a .22 revolver but then thought it would be cool to have one that can swap cylinders to shoot either .22LR or .22 WMR, so now I must have one.
Two that I am looking at now are the Ruger Single Six Convertible and the Taurus 992 Tracker. Cost seems to be a wash.
Here's what I can gather so far as far as pro's and con's.
Ruger Single Six Convertible

Pro:
Legendary Reliability
Asthetics, better looking that the Taurus IMHO. Amazing fit and finish.
Con:
6 round capacity
Single Action only
Taurus 992 Tracker

Pro:
Life Warranty - not on the owner, the gun (pretty cool)
9 Round capacity
Double or Single Action
Con:
Questionable reliability
Lower Resale Value
Weight - not a problem for me.
That's all I can think of. If you can think of any additional Pros\Cons please feel free to add. I do not know what the trigger is like on either of these guns. So if anyone has any insight please let me know. Also, if you are aware of any additional guns I should be looking at I'd love to hear about it.
