Those tank adapters are REALLY nice, and are very helpful getting the gun to fit right... That being said however, definitely shoot the gun "as is" for a little bit. Personally, with the smaller tank the TalonP fits better than a standard Talon or Condor. The adapter does add to the overall LOP- not much mind you- but it does make it longer. Just something to consider. I'm not knocking the tank adapter- I used to run one on a Condor many moons ago. I loved it.
I really wish he would make thread-on LDC's. They're ridiculously quiet for their size and well made- but I like being able to remove the LDC with no tools for transport... If the added length doesn't bother you, no biggie.
9 inches added to it and 175.00 ? I think I will pass.
For whatever reason, I always thought the TalonP fit me better. It's not that much of a difference, but the smaller dia. of the TalonP tank is apparently enough to be comfortable...
