This is Wieslaw Chrzanowski, at Wilcza 16 St., dated early Sept. 1944. He was Speaker of the House in the 1990s, and passed away in 2012. [see edit for correction on that last one]
If possible, please be detailed with your ID, for instance, I think this pistol has target front sight, and seems more like K frame than N frame to me. I see characteristic SW medallion grips, but I hope someone can be more detailed and id the variation.

Edit: There were actually 3 Warsaw Uprising fighters by that name. The one in the photo is NOT the one who became speaker of the house. The confusion is all over the internet, so sorry for falling for it initially as well.
