Warning: This is a 30 min video. Some folks hate longer videos, so I've taken the liberty of breakign down the video into chapters, which might help some folks.

Chapters
00:09 showing clear.
01:24 Trigger weight and thick wall.
03:11 Testing the irons.
05:44 Zeroing the optic.
09:03 Testing the optic's zero.
12:06 Added an optic shim due to mitigate possible optic cut issue.
12:29 Is this an optics issue or optics cut (gun) issue?
19:06 Rail issue due to nonstandard 3notch rail.
21:26 Rail issue is preexisting (has been occurring the past two years with Tisas single stacks).
24:43 Durability of the gun (hasn't been cleaned or lubed since I first received it).
26:29 Mag availability.
28:35 Cyelee optic talk.

The above should help folks that don't want to watch all 30 minutes of the footage. A large portion of the video, I talk about the optic, the optics cut, and the rail, which are negatives of this example of the Carry DS9, sadly.
