I like the SIG-Sauer better than the Glock and prefer .45 too. Sounds like a “win-win” to me.
Sig is my fav mfg. and I love mine, will take any Sig over any Glock. All mine are both incredibly reliable and incredibly accurate.
That being said, Glock is a good weapon or so many would not be using them.....
Wilson Combat is the only 1911 I’d swap for my Sig......
I think the Sig is a great gun, but I’m left handed and the controls on the left side of the gun are a bit further aft than most handguns. That makes it more difficult for me.
