9mm
I use an East German 9mm MAK for concealed carry (actually 9.3mm).
I recently purchased a M&P9 Shield M2.0 NTS to replace the 9mm MAK but haven't used it yet.

455 Webley Revolver VI
Owned a Webley 4” Mark VI with “Garda Síochána” Markings. Sold it a couple of years ago. I really like that that gun. Was in excellent condition but it is time to start selling off my collection.

I would love to own a .577 Howdah. Historical antique attraction.
