I finally got it put together this weekend. Barrel fitting done. Optics on board. I started the break in shots. Runs like a sewing machine.

Hi Reflex. An interesting looking build. How well do the barrel slits work as a compensating systems? Do they slow the slide velocity down as effectively as some of the larger screw-on types?

Purely a personal preference, but I don't think I'd be comfortable with the scope sight.However, given the accuracy usually achieved by your builds, I can see the advantage of a scope vs a micro red dot - especially for long distance.

The ports seem to be doing their job. I shot it about 100 times in the last few days. Zero sign of battering and I am watching.
