That's a shame David. My LGS has pretty much had a good supply of firearms. When this pandemic started, they quickly ran low on a lot of them, and into the summer, I mostly saw several Turkish gun (Canik, SARs), and makers like AREX that I've never seen there before. Makers like FN, HK, Beretta, CZ, etc., were tough to find, where they once were more prevalent. I'm noticing now, these brands have started to make an appearance again, while some makes (like S&W) were always available there. In fact, they tried to talk me into a HK VP9SK with the button mag release, but I already have the same firearm with the paddle release, which doesn't bother me. The one thing I've noticed however, is there doesn't seem to be a lot of calibers besides 9mm fireams. I have several orders waiting with them, specifically the S&W M&P 2.0 45 compact and FNX Tactical 45, that I've been waiting over 6 months now for (ironically, as I'm writing this, they just called and informed me that my order of the Beretta 92X Performance 9mm just came in. I'll visit them tomorrow
).
As for ammo, they usually have the common calibers and sell it at below online prices that I've seen. They just recently ran out of the 9mm the past two weeks, even though ammo there is rationed to 1-3 boxes per person. Maybe tomorrow they'll have some.
Well I wish you and your LGS luck, and hope they can get back into the business soon, It does look like more firearms are becoming available, so maybe that's a good sign if that's happening elsewhere as well.
