I lost my 1911 bug long ago. I still think they're very handsome, but there are many other firearms i would rather depend my life on. 1911's are just so finicky.
Besides, how are you ever realistically going to shoot any better a 10yd group with a handgun than this group that my used box stock P7 with full power +P+ JHP ammo did, the first day i owned it?
You seem to group just as well with your sig, so for the life of me, i don't know why you'd try and replace it with a gun that's really just as large.
With the Fastfire II HUD on it and any kind of decent lighting, my P7 has the accuracy of a lightning strike from God out to 25 yards.
I had my LCP to the range the other day too, and was shooting about 1.5" groups off hand at 7 yards with it, using the Crimson Trace laser.
