I'm looking for insights from the folks who have experiences in both TS & TSO.
I have added Dawson Precision FO front sight, CZC Adj. rear sight, and LOK thin grips to my TS to enhance the shootability and comfort. I've been quite happy with this setup until I got to handle/shoot my buddy's TSO. I still do prefer my thinner FO front sight and the grippier LOK grips than the TSO original counterparts, but OMG... my right hand fits soo much better in the TSO's "revised" grip geometry (Btw, i do have medium size hands). I just love how it fits my hand as it made me to feel like TSO was much smaller gun than TS. The revised geometry of TSO grips provide easier trigger manipulation movement (primarily due to the shorter trigger reaching distance) and safety manipulations as well.
Unfortunately (perhaps fortunately), these enhanced "feelings" did not translate to the improvements in accuracy. This could be due to the fact that I didn't get the opportunity to spend lots of time on TSO. OR perhaps, my TS can still shoot better than my skill. lol
