Hi guys..first this is not about any advise I received on the Forum. This is an alert...I was having problems with my Interarms ppks about a month or so ago and was hoping someone here could direct me to a Walther gunsmith. Several were suggested. I chose M&M and spoke to him. "...no problem, send it.." I sent the gun, he kept it for about a month and returned it. I took it to the range and experienced the very same problem. I called him, he claimed he fixed it and fired it with several loads from different Manufactures. All I'm saying here is I would not recommend M&M personally. I hold no forum members responsible just passing on my experience to you....
