Looking to purchase my first handgun and I need help. I really am down to a fullsize M&P 9mm or a (gasp)Glock 17. I have looked around and nobody around here seems to have an M&P that I can rent at the range to fire. I have looked and held and held and looked at both for about 3 weeks now. It seems to me that the M&P feels a little better in my hand, but I dunno. What are your thoughts on the differences between the two? oh it was a gen3 Glock if that matters. Thanks in advance.
