TLDR: Stan (the owner) is an uneducated, hard-headed, lazy, paranoid old man. Take your business…read moreelsewhere if you value your time.
First, there are his working hours. I've pulled up multiple times at 4:30PM, 30 minutes before closing DURING business days, and the store will already be closed up. No explanation, nothing. On TOP of already being open only 4 days per week, sometimes Stan will just take 2 more days off unannounced. You will just show up at his storefront only to be greeted with a sign that says, "taking Thurs and Fri off, see you next Tues."
Also, I visited once to pick up ammunition and Stan is at the counter doing paperwork on his laptop and informs me I will have to wait for him to finish. I politely answered that's fine. Then proceeded to wait 20 minutes doing nothing before he "finishes" his paperwork and helps me. There was NO other person working at the store. Based on my experience, Stan clearly does not value your time, only his own. He may have lower fees but it is NOT worth your time. If you DO plan on visiting for God knows what reason, call ahead. But you're much better off taking your business elsewhere, plenty of good FFLs in the area (greta's, smokin b, etc)
Third thing, Stan does NOT understand current California Gun Laws. His mentality is simply "My Shop, My Rules." You cannot reason with him, if you print out CA penal codes he will just throw it in the bin. He is not one of those pro 2A shops that wishes to empower his community. He is a paranoid conservative owner who only cares about himself. And if he THINKS you will harm him or his business in any way even if what you're doing is completely legal, he will just yell at you. He simply does not care.
Despite holding an FFL07 license to manufacture, the owner panicked over a completely legal Glock upper assembly. It does not matter if its a gen 3 or gen 6, whether the slide or barrel is serialized or not, they are BOTH NOT FRAMES OR RECEIVERS in the eyes of the CA DOJ. I urge you Stan to read up on CA DOJ Penal Codes. He even went so far as to say this transfer will "put him in jail." Stan has no problem transfering a gen 3 upper. But if it is gen 6 upper, he will freak out saying that it must be DROS'd as a complete firearm, even though the gen 3 he transfered was NOT registered as a firearm.
He seems to believe ANYTHING that is serialized is a receiver or frame which is very far from the truth. First off, a handgun part cannot EVER be classified as a receiver, that is reserved for LONG GUNS. Handgun parts can be classified as a frame. And secondly, a handgun upper assembly is NOT classified as a frame because it does not house a trigger mechanism or sear. LOOK IT UP in CFR handbook. He is just a paranoid old man who only cares about himself. And he will accuse you of trying to ruin his shop based on nothing but his own paranoia.
Mind you these experiences all took place within about a month. It doesn't take long for Stan to show his true colors. This is my final warning, stay away from this shop. I don't know what it was like before but I can tell you what it is like right now, and it is not a friendly 2A shop. The owner is a lazy and selfish paranoid old man, who you do NOT want to deal with.
