I'm looking to buy my first striker-fired 9mm, for the dual purpose of home defense and concealed carry. I have narrowed my choices to the SR9 full-size and the Smith & Wesson M&P 9 full-size; both are double-stacks and very close in size, feature set and cost. How does the SR9 stack up to the M&P9, in terms of reliability and accuracy? Are there any known issues with the SR9? Thanks for the assist, guys.
