I am thinking about selling my Scorpion EVO pistol and carbine and buying an Angstadt Arms pistol but I can't find one locally to shoot before I buy.

I'm looking to buy a 9mm pistol that takes Glock mags and came across Angstadt Arms. I have a GHM 9 which I like I lot but I don't know how long it's going to be before the Glock mag lowers become available.

Does anyone have any experience with the UDP-9?
