I've been shooting mostly .45 since the Coronavirus uprising ammo famine began. This is due to having both large and small primer brass on hand in large quantities. This has allowed me to extend my reloading ability. Especially after finding thousands of large rifle primers from my competition days that I'd forgotten about.
The 4506 I'd been carrying wouldn't set off the harder rifle primers with one hundred percent reliability, so I went back to carrying the 1911. I'm on the range once a week and I hardly ever see another shooter with a 1911, let alone a .45. It does make identifying my brass easy. Single stack .45 1911s might be increasing in sales at Wilson, for whatever reason, but I certainly don't see a general trend in the market.
