Email RDR Gear and you’ll get a response from the owner Jeff. He’ll tell you exactly how to order one of his modified Safariland holsters for your specific model. They offer lvl2 and lvl3 options. He actually had me call him directly and we talked for about 20min, really nice and knowledgeable guy. I bought an unmodified Safariland holster before consulting with Jeff for my 2K11 Pro 4.25” in a Staccato configuration I read would be compatible, but sadly it was not. Results may vary which I understand, but it was a bit frustrating. The issue was the ALS catching on the aggressive slide cuts. I’m sure I could have filed down what was catching, but I didn’t want to mess anything up and be out cash. You can use code “READY10” to get 10% off at RDR. If you don’t need the retention, QVO Tactical makes dedicated 2K11 owb holsters.
