I would totally forget about Taiwangun, as for the case you need to return something, their return policy and customer service is awful.
1. You have to pay the shipping costs yourself in case of returning (no good store does that, at least not here).
2.) They take like forever to send you a shipping label.
3.) They stop answering you during the process.
Returned the SP2022 and got a Beretta 92FS and TM 1911A1 (both Springers). I got both for the case that one of them doesn’t work. If I have gotten my refunds back for the AEP (im still waiting for the shipping label. I don’t recommend buying from Taiwangun) and my SP2022, if so I will buy a SSX23 or something else if it is enough to cover most of the costs.
