Not too many years ago, I was a serious competitor in combat and NRA matches. I shot a full sized Colt Series 70 45 ACP and won my share of contests. One day the collet bushing on my Colt broke right in the middle of a match. I went to the truck and got my duty gun, a 45 Series 80 Commander. I finished the match with winning scores but more importantly, I learned a few things. The Commander came out of the holster quicker, acquired the target better, balanced better, and shot excellent groups. I had never considered the Commander as a match gun. I continued to use it for both NRA and combat matches and improved my scores considerably. Now that I'm retired, I no longer compete nor do I carry a duty weapon. I bought a Series 80E S/S and when I need to be armed, that's the gun I strap on, and yes, I still have the Series 70 Govt Mod.
