Maybe because you want a little more capacity, or something that feels a bit more substantial in your hand? If you like the M&P Shield look at the M&P 9c (compact) and/or the M&P 9 Full Size. The 9c was my first gun and my first CCW. I later got the Shield in 9mm for its enhanced ease of concealment and it's similarity (same manual of arms) as the 9c. The benefits of the 9c is that it's also relatively easy to conceal, it has a 12 round magazine capacity (compared to the 7-8 round capacity of the Shield) and it accepts the 17 round full size magazines.
I carry my 9c or Shield every time I leave my house, without fail. I work at a machine shop and am not allowed to carry there, but I lock my M&P in a lock box tethered to the passenger seat. It won't stop a determined thief with time on his/her hands, but they won't be able to just smash-n-grab and take my pistol.
I've shot both and I like the mustang a bit better. Only cause I like the way it fits in my hands. Both are excellent performers though.
Thanks! I am leaning towards the Sig because she has shot it and knows it works for her. I can't find anyone local that has a Colt we can shoot and I don't want to get one without her shooting it first.
That would be a good choice. I love my Sig. I have a P229. I've had it for two years and have run over 3,000 rounds though it. I had a couple FTEs in the first 500 rounds, but since then it's been perfect. They are very reliable - that's why I chose a Sig.
Sig does make some great guns. I've never had any issues with mine. I have the Sig 716 AR10 and it hasn't had one FTF or anything. I've put some crappy steel cased ammo down it also. Either way sig or colt they're both pretty reliable.
