Before you buy, try to shoot one. Some fit slightly differently. I'd look at some of the Kimbers and if you can justify it Ed Bowns and Wilson Combats!
Like you I have a Dillon 550B reloading 9mm and 45acp. I started with a MEC Jr. back in the 1970's and quit shooting. I restarted back in January and purchased a MEC 9000N and have reloaded over 10,000 shells 12 ga.
I love reloading and would be glad to help you if you have any questions.
I have the Dillon tumbler with a lid and absolutely no dust or anything gets out. I am using the ground corn cob media. It does a remarkable cleaning job!
I tired to purchase a Beretta in Florida last year since I own a condo there and found out that I have to have a Florida ID or shipping to an Indiana FFL for transfer.
