Colt of course as iv said to you before though Sig is awesome as well as RRA. I have several colts as well as a Sig scorpion, and several others. My main carries are dual Colt GCSM that I have done alot of work on.
Leaving Glocks as in u are going to sell them too? Ever considering "multi" platforms instead, by owning all kinds?.
I have smiths and i have glocks and even a bond arms snake charmer which is sick but my carry weapon and range weapon should imo be the same. I am tired of my glock but still love it. Its like the wife or gf you cant stand but she always makes you a great dinner and is there for you lol
