YES!
We must all do all that we can.
I have better spent $50.00 at the range convincing a few previous anti-gunners to support the 2nd Amendment than a $50.00 donation to a pro-gun group could ever do.
However, we must financially support the pro-gun groups too. They have the bigger voice.
The great thing is that it is YOUR money to spend where you think it will do the most good!
BTW, welcome to FR.
