I know in my case, .45’s are almost non existent. All I see around here is 9mm pistols and 223/5.56 rifles (plus a few shotguns). It seems like gun manufacturers are mainly producing those calibers & guns being snap up in the majority during this gun run. During August 2020, I ordered 3 guns. A S&W M&P 45 Compact, a FN 45 Tactical, and a S&W PC 500 Magnum revolver. Out of the three of them, I figured the 500 would take the longest to come in. That one came this past February, and I’m still waiting on the 45’s. Since then I’ve order other 9mm pistols and some of them have came in also. Fortunately, before this gun run I bought the compact XDe,XDs, and XD Mod.2 all in 45, and the 5.25” XDM in 10mm.
