ptper It's always a good idea to become intimately familiar with gun laws where you live, and where you plan to possess, transport and potentially use firearms and ammunition. How long have you owned firearms?

Getting the information you are asking about from a car enthusiast site is discouraged. Worst case is you are found guilty and convicted of a felony. Unlikely, but that's the game you are presently playing.

Try Google searching, and focus on gun law specific websites, and the state legal code of your state, city or District. Are you in Maryland, or the District? The District has some of the most restrictive firearm laws in the country. You are advised to become intimately familiar with them.

Local gun shop owners and employees are, on average, orders of magnitude more informed than anonymous posters on car enthusiast sites. Take a trip down to your nearest LGS or indoor pistol range, buy some ammo and talk to the people there. The local police station can be a source of credible information. Some LEOs are willing to answer direct questions on gun law topics, some aren't.

Car enthusiasts in my view are best to give pointers to others, for reference reading material. Offering specific advice or interpretation is a high risk endeavor - example: magazine capacity regulations.

Summary:
- don't take advice on law-related topics from car enthusiasts, you are at risk of committing a felony if you or the car enthusiast is wrong
- use Google to find gun law sites and the legal code for your geography of interest
- visit the LGS or pistol range and talk to people there
- visit the local police station and talk to people there
