I know all about hindsight!!! I have excellent HS vision.
I have considered more than once picking up a 7.5" version, but since I have others in the stable that don't see enough range or field time, I have yet to do so.
As far as the 4" guns go, I LOVE mine. Probably the most practical all around outdoorsman's gun for long term use far away from a gunsmith or spare parts.
I like to look at mine as the perfect SHTF revolver (for where I live)since they are darn near impossible to break.

The Tikka T3 in .308 Winchester is the Glock 19 of the rifle world.
