Well, we all know that all makers have a bad one now and then, and sorry to hear it, but it looks like you got one of SIG's.
I look at them all with suspicion these days until I see how well things go with them. I no longer buy Kimbers, Springfields or Glocks, and a few others, due to repetitive failures with their products. It one thing to have a problem with one gun, but when you keep getting new ones and they dont work, well, then I go elsewhere.
So far, SIG has been real good to me. Right now, I have 12, including a couple of used guns and even the "dreaded" Mosquito. They all have worked flawlessly, either new out of the box, or used from a private/dealer sale. As I said, they provide everythinng you need, right out of the box, all you need is ammo.
I've probably owned close to 20 Colts over the years, maybe more, (hey, I'm getting CRS
), they all pretty much worked right out of the box, and most of the newer ones with any type ammo. They all had good triggers and were accurate. I still always had to do "something" to them, be it sights, or change out the MSH and triggers, (personal preference, I like arched/short), but other than that, they worked. The problem with all the other 1911's is, they arent Colts. Many have their own ideas as to what a "spec" should be, and they all vary in material and QC. They may look like a 1911 of some sort, but thats about all they have in common.
