I can make use of Impacts outside of CQB. If you're good and accurate, you can lob them against a tree trunk or off a rock right beside your target. But in outdoor situations, I'm just a lot more prone to using my M203.

The timers are... yes, flukey, but I find they are pretty good if you stringently maintain them. You should oil them a minimum of two drops on the seals once a month if not using, and definitely follow the guidelines for filling (drops every two fills). I can count on my timers going off between 4-7 seconds after the spoon is released (on the long timer setting.)

But the impacts are far more reliable. If you only carry one, carry an impact.
