Has anyone had used a Milt Sparks Versa Max2? I've used one with a Colt Commander (my friends) and I like it a lot. I've emailed the company and they said that they made one for the M40. It's a great IWB holster, just wondering if anyone has used one for the M40 Also wondering about grip socks. I've seen an Uncle mike's on an M40 and it really impressed me. Any other brands that anyone would recommend?
