Good for the price
For the price I can’t complain. The mag release is not as clean as I would like, hard to seat mags, and then when I press the mag release the mags do not fall free, I have to yank them out. Maybe in time they will loosen up . . .

Not good...but then great.
As a dealer, I have sold many PSA made products and always good reports. I got the Gen4 9 for myself, haven't gotten anything for myself for while so what the heck. Fit and finish is top notch, mags fits nice and snug, no wiggle. I loaded up with Federal 115 fmj. Pull trigger, bang and next round wont fire. I eject mag, clear, reload and chamber, bang. Then wont fire. Every round was same. Chamber, fire and then hammer doesn't drop. Clearly, something big has happened. Open it up and find small parts scattered inside the lower. There is a spring wedged up against the trigger assembly, that explained the no trigger working issue. There was a small metal piece near the bottom of the trigger too. Then I see the source of the problem. The buffer tube was not fully inside the receiver. It needed one more full turn. The buffer retainer was able to come out of its hole along with the spring. This lead to total failure when firing. While not all giddy about this oversights, as someone should have noticed the buffer retainer was not correct, the problem can be corrected without too much ado. I corrected the buffer tube and put a new retainer and spring in. Took the trigger assembly out and cleaned everything out. Put it back together and ran 150 rounds without a flaw. The pistol is a joy to shoot as I hoped it would be. And while this should have been noticed during assembly of the pistol, I forgive the error completely. Everybody makes mistakes and all of the product I've ever gotten from PSA has been great. I reality, I would give this 5 stars yet, but because I had to mar up the buffer nut a bit by unscrewing it and retightening it and I had to put a new spring and buffer retainer in at my cost, I taking one star away. I'm sure my gun was a rare exception and just an example of a simple mistake leading to a dead on arrival firearm. But I still highly recommend this pistol and I will likely get another one or two when back in stock.

excellent function
This thing chugs chugs and chugs the ammo, all types of ammo and weights. Works every time, hand guard comes off very easily for swapping flash can. 1/2x36 threads so look for an adapter if you need 1/2x28" threads.
