I have done a few orders with them. I will have more in the future. VZ2008 package they had last spring, AR build parts, their PA10 kit, and the 92s police trade ins.
Only issue I had was the PA10, I was one of the ones mixed up in the great buffer fiasco of 2014. PSA sent the replacement parts fast, free, and no return of the wrong parts.
Lessons learned for working with PSA:
1. Order and forget. Like stated, they are not fast but they are cost competitive and will get you your stuff. I don't care that they charge me right away, makes the account easier to balance.
2. If ordering an FFL item, ensure your FFL is on file first. One order took almost a month. Took their standard 2-week processing then another few days for then to notify me it wasn't on file and for my FFL to get filed, then the shipping time. Every order since, has been just two weeks from order to filling out the 7743.
3. Get an account in ARFCOM. Yes, you have to hold your nose while visiting that place. It really makes you appreciate the moderation here. The PSA industry forum is by far the easiest way to get ahold of customer service with PSA.
4. Get a second job. They are truly the meth dealers of the gun world. Every day they send you specials and just when you think you are content with your gun stash, here comes another e-mail of stuff you MUST have.
