Yeah canik makes a solid gun. It's not a 100% clone whereas all parts are interchangable, but they are very nice guns.
Mine was the S100. The full size one. I'll be entirely honest, I like the compacts more.
While I have done some mods to mine, I have to say, it's my favorite full size 9mm handgun.
cajun gun works has/had a lot of upgrade parts.
I switched to a different part and omitted the mag brake because I like mags that drop free. The original had the brake in it that would prevent the mag from puking out entirely.
I also replaced the sights. And grips, but those were more personal preference than necessity.
