I usually have a list in my mind of guns I want. I shop around and keep an eye out. The one I get cheaper is the winner. Then I move on to the next. But I buy way too many guns and have a dozen that I have never shot. I like buying guns as much as I like shooting them. My buddy said that I really should consolidate my collection.
Here's how I would address those two choices. The PSA is new and listed at full price. Once the flurry of new rubs off, blem discounted guns will show up. Probably 5.56 guns on sale when the .300 Blackout version shows up. I'm waiting on the blem guns before I buy. I'd hate to buy one for $1099 only to see a $899 blem black Friday sale. But I have a several Dracos to keep me entertained.
The Stribog is imported, so that can always get stopped. PSA is domestic and has a little buffer from being banned. I ended up with an A1 as it was cheap ($450 with FFL fees). I wanted an A3, but not for $800. This happened when the braces got on the naughty list and everyone paused on short guns. 9mm is cheap and pleasant to shoot. Even suppressed, the 9mm with subsonic ammo is an absolute joy. The 5.56 suppressed is just less loud. 5.56 subsonic is my Ruger 10/22 .22LR.
