With a pistol it's realistic to hit a target accurately at 100' (man sized target), but getting a BB out to 200' is a little more difficult, but certainly not impossible. I've had TMs that can do it and some that can't. All around they are reliable and reasonably accurate out of the box, except the FM 5/7, which doesn't like to cycle properly in cold, or hot, or days ending with 'Y'.
You can increase your velocity a little with a tightbore, which is pretty easy to install, and you consistency with an upgraded rubber and modding the hop arm to apply even pressure. These changes are not typically necessary to have the pistol run well, but there's always things you can do to any airsoft gun to up performance. Continually modding or upgrading an airsoft gun isn't really strange, neither is getting it to where you're happy and leaving alone at the 'good enough' level, depending on your tech'ing skill and cash flow.
Most TM pistols shouldn't require anything to run well, but there's always upgrades if you want to go that route.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
