Another howdy from Texas. Sorry for the wait, I was stationed in SoCal in the 80's and had to endure a waiting period (I thought it was 15 days) the first time in my life.
The only waiting period I had ever dealt with was the 3 day marriage license in Texas. I sure wish that was 15 days, or months. I regress.
Enjoy that pistol. I'm warning you, they can be as addictive as crack. That's what I hear anyway.
So I got my Mosquito last Wednesday and took it out a couple times this past weekend. And, yes, it is addicting. In the two times I went to the range, I used about 800 rounds. Yes, I realize that is a large amount of ammunition, but you have to realize that it's only ~$15 / 500 rounds and fatigue isn't really an issue with a .22 caliber.
Welcome aboard. I couldn't handle waiting ten days. The only wait I had to endure was the cashier couldn't figure out how to give me the credit I had coming. Of course I live in a state you could do about anything.
