RE: S&W M&P vs. Glock
I think it is all preference, have you had an opportunity to shoot the M&P? I own that and a Glock 22 and I prefer the M&P in .40 myself. The switchable hand grips make finding the size that fits you very easy. The M&P I recieved has a pretty crisp trigger pull where as my glocks is a little heavier (not sure the weight). I would say you should test fire them both at a range if possible. I wasnt sure I would like the M&P until I did now I prefer it over the glock, but thats me.
