Now, the M&P 340/360 differs from the PD models in some ways, one of which is they use a PVD coated (black) stainless steel cylinder, instead of titanium.

Thanks for the feedback and I should have been more specific in that I am considering models with the steel cylinder. Yes, I would really like to demo one before I buy, but I wonder how likely I am to find one for rent at a range.

So, do you prefer the single/double action models or the double action only models? Also, has anyone heard reports of failures from a mechanical standpoint?
