Is there a limit to the number of guns I can put on my permit?

No. There is no limit to the number of guns you can put on your permit. You will, however, need to perform a live fire qualification test in the presence of an approved instructor for each semi-auto pistol that you want to have on your permit.  As for revolvers, you need only qualify with one (any make, model, or caliber) to be able to carry any revolver. Rent one of our classroom guns if you like. See TRY-BUY-QUALIFY™.   There is no restriction on the caliber, or the type of firearm. You may qualify with your full-auto mini-Uzi, for example, if you like. Just be sure it's a legal NFA gun, please.   We will sign you off on six (6) guns free of charge, included in the course fee. Additional guns are $5.00 each for us to certify. We do this not to charge you unnecessarily, but to discourage those with large handgun collections from joy-shooting dozens of guns during class time -- guns that they would NEVER seriously consider carrying concealed. Yes, people actually do this. Feel free to stay after class at the range and shoot as much as you like.
