Q. What handguns are approved for sale in Maryland?
A. Go to Maryland State Police, under Quick Links, click on
Firearms/Permits/Licensing for a complete list of approved handguns for sale in Maryland.
There's also a 20-round limit on magazines purchased in MD. I don't believe there's a limit on possession of magazines greater than 20 rounds, however; some guys I knew bought their mags in PA for that reason.
My condolences on living in such a gun-unfriendly state. I'm currently planning on passing on a job offer there, due to that and their higher cost of living relative to Kentucky.
EDIT: Thanks to rfawcs for the catch, 20-round limit, not 10.
