Great Scot, I recently inherited (even though he's still alive, thank God) my Dad's Walther TPH. It's the Interarms .22 LR version. I LOVE IT! At first it would not fire in double action mode; however (in answer to Seven High's question, yes, there are), I sent it to Mike at M&M Gunsmithing, 2423 Carter Grove Rd Unit B, Hazel Green AL 35750 (you can reach him at 571-276-7676 8:00am-4:00 pm CST), and it came back PERFECT (no surprise, as he worked at Interarms for 15 years and knows those TPHs inside and out!). Mine shoots best with CCI MiniMags, and I carry it in my front pocket in an Uncle Mike's # 2 Pocket Holster; it just disappears in jeans; I forget it's there. I hope yours works for you as well as mine. =D
