I like the snag free slide release idea. Might be something to add to my 365 build. One thing about Sig, they make it easy to tailor your own pistol with the best details for your needs.
I actually just saw this on a YouTube series of videos. Pretty impressive but I don’t know if I would want one particular gun having me make a conscious notation that the sighting is different. Probably not a huge thing but a thing none the less. The tiny micro compact gun things just doesn’t fit well with my giant hands (as much as I want to).But I'd like to keep it as small as possible which is why I started with the 12 round extended mag first.
edit: sorry, I didn't see that the topic was somewhat older.
