Cons
-Overly complicated internals
-Lightweight frame makes shooting .357 magnum a tad unplesant
-Lack of aftermarket parts (sights, grips, etc)
Pros
-Unique look
-Lightweight
-"different" recoil impulse from firing out of the bottom of the cylinder
I had one for a few months; shot ~1000 .38 special out of it, couple hundred .357 magnum. Eventually, something went wrong with the internals and I couldn't open the cylinder. Ended up sending it back to the importer for repairs and they just gave me a refund since they couldn't fix it. So I bought a 686 to replace it with.
