Glock 19MB ?

Hi Tony, quick question. I got a replacement service weapon - a Glock 19MB. This is a Gen 3 European model with an ambidextrous mag release - ambidextrous as in “the square button sticks out on both sides”, which means it pinches my middle finger when reholstering in my usual JMCK.
If I were to order an IWB 3.0 for this gun (with provision for the “extra” mag release), would this be a quick-ship or a custom order ? Thanks in advance !

I believe you've already emailed me regarding this and we have you in the queue. Let me know if you have any other questions. Thanks
