I have the glock 17 version...even though the msrp is around $400, they typically sell on sites like gunbroker for $600...I was looking for one 12 months ago online & they were closing for over a grand each for the 9mm glock versions during the hysteria...
What I'm saying is, for $350 its impossible to go wrong...for less than $100 you can buy hardcore AR style front sight from red lion precision. I plan on adding that as well as possibly a telescoping forend that they sell as well that allows you to add a red dot or whatever accessories you want, rotate them 90° or more keep zero when you fold the gun....
What sold me was the super compact size when folded in a decent pistol caliber carbine....my plan was to follow up with a g26 for ccw, then my xd subcompact stole my heart....but I'm still happy to have it with such a common mag style....FYI, there is a less common glock 19 version which works with g17 mags but the 17 won't work with the shorter 19 mags....they both work well with a 33 round 'happy stick'
