I have the T3x CTR with the vertical grip and I definitely prefer it to the swept back, more traditional rifle grip. If my other t3's had the option, I would change them out for vertical grips in a second.
My T3 still wears a factory stock and I have had no issues with it. Im not familiar with the Savage, but I would guess it is a little more solid than the standard Remington synthetic stock. If the stock is your main concern, there are some aftermarket replacements. The only modifications to mine have been a limbsaver pad, paint, and free floating the barrel. I probably would have done those things to any stock though. Mine is a real shooter.
I don’t know if mine was from a bad production run or not but mine does not fit my T3X. Later, I found several others on this site had similar issues. Beware, once you open the package and try it, you are most likely stuck with it. I have yet to find a vendor who will accept returns for it and for
this reason, I am not inclined to try another one.
