Sig 226/40SW
Pure power with a great feel.Love the way it rocks when the hammer falls.Easily reacquired sight picture and plenty accurate.Mine's been totally reliable so far.Gotta love it man.
It's a toss up. I like the MK40 for everyday carry. The P229 for cool weather and daily carry with hicap mags, and the S&W 4006 for the range or matches.
The only bad thing is that I had to buy it from EAA. I have never had worse customer service from a company in my life.
From the top to the bottom they have an uniquely anti-customer service culture.
Everyday carry would have to be my G27, but all round .40 would either be my Browning HP Practical or the hybrid SIG P229 Sport I shot in the IDPA match last month.
I have limited experience with .40. I've only owned a G35 with aftermarket barrel and P7M10. I like the G35, but by a large margin the P7M10 is my favorite auto of any caliber.
