I have the only vote for the Sig so far. Mine is actually a 2340 in .357. Nice feel, good trigger, reliable and accurate.
I do have a Glock 17 but haven't had a chance to shoot it much. It seems OK but hasn't sprung the voodoo on me like it does most folks. The XD's I've tried were really nice too. Tried to like the M&P but can't come to like the grip shape well enough to want to shoot one.
I have the most experience with the XD line of pistols. I have around 12k rounds out of a XD9sc. I also picked up a 9mm and 40 XDM full size.
I just got the chance to shoot a CZ P01 and I have to say that I think I'm sold on the CZ for my favorite. I'll be picking one up this summer and see how it does for me in 3 gun.
I've been packing my Kahr CW45 around now
for over a year and it suits me just fine.
But my Ruger LCP see's about as much time.
While the Glocks are fine weapons and I have
no negatives about them I just don't care for them.
I have handled several glocks and now own an M&P and would never go back, it is more comfortable and seems to just point better, that being said I liked my glocks, just prefer the M&P...
