I kind of tend to go "value" on guns, and all of the following were less than $400, and the Taurus PT111 G2 was $225 including the transfer fee.
Taurus Pt111 G2- A great little carry gun. Mine hung on the third shot and has been flawless for about 500 rounds after that. Eats everything and is actually pleasant to shoot for such a little gun.
Astra A75-Kind of the opposite of the Taurus, all steel and very heavy for it's size. This is my house gun. Never a flaw in the 7 years I've had it. I think it was $260 in new condition. I bought some expensive parts for it, and never used them.
S&W 5906- It's a police trade in, barely shot, and barely carried. Was $359 + ship + Transfer.
Canik TP9V2, $375, including transfer. Flawless so far, with a great trigger.
Sarsilmaz/EAA k2 45, a big 14+1 45ACP, all steel. Perfect, so far.
Tanfoglio "Mossad" 9mm, both in full size and compact, same as original "Witness", both are satin nickel, and shoot great. I bought the compact first and liked it so much I got an even prettier full sized one. Both were under $400, including shipping and transfer.
A Pietta SAA "clone". Mine is from Century, 22LR 10 shot. They sell the same gun under a lot of different names for all different prices, some over $400. I havent shot it yet, but I don't expect any. Action is very nice for a stock gun that was less than $325 including the transfer. All steel too, with a nice Walnut grip.
Some gone away great cheap guns:
Astra A80(two of them) and an A100. All were flawless and I only sold the A100 because I needed cash, and I got an insanely high price on GB for it. A price that made me laugh, because it was just ridiculous.
Astra A75 in .40, even being all steel, it wasn't fun to shoot. Sold it and bought the 9mm.
Dan Wesson 15-2 .357 magnum. A great shooter, with a bad finish from holster and slight rusting on the barrel shroud. I got it for $200 at a pawn shop, sold it to a friend who just offered me $300 for it one day when we were shooting it. It's been refinished and now looks like a new SS gun. The two DW .357's I have now were under $350, including transfer. My favorite revolvers, period.
EAA Witness .45, in "wonder finish". I got it for about $380 on GB. Zero issues, I really regretted selling it.
