There is a lot of misinformation out there. Three of the worst sources of information are:
1. Gun Dealers
2. Firearms instructors
3. Police.
This is from a gun and ammunition sales site;
. AMMUNITION PURCHASE
Purchasing ammunition in Delaware is very strict. In order to buy ammo in Delaware, a CTPP, gun sales permit, or long gun/handgun eligibility certificate is required. There isn’t a background check but buyers must be at least 21 years of age and provide proof of valid ID. The same goes for all online purchase ammo shipped to Delaware.
The problem: A CTPP is a Connecticut Pistol Purchase certificate.
Another example. A trainer for the Maryland Wear and Carry tells his classes that the Delaware concealed carry licensee exemption for over 17 round magazines was taken out of the bill
The trainer that I had years ago in Delaware said that once you have a CCDW license it is a felony to open carry. When I asked him to site such a law, he got angry and said it has always been the law.
