Yes, the top one is a 34 slide. I don't think I have seen anything specific for the 34. (I haven't looked) It would look a little more clean with another 3/4" of those rails. I was hoping DB would come out with a 26 or a 43 as well. I would like to update my frames for those.

Thank you on the quality. It's basically cheating using a bambu and the 300blkfde settings. There were a few places on there where there were strings. If it was inside the receiver I just took a screwdriver and scraped them off. I did break one of the extended mag releases while assembling this and had to reprint it. The part of the mag release that looks like a P, the bottom part of the P broke off once. I am not sure if it would need to be thickened up or just less of a goofball installing it (me). I really like the looks of the frame though and am excited to shoot it.

**Corrected incorrect wording of safety to extended mag release from comment below.
