gen 1-4 17 barrel will fit on this version. I have tried it with my buddy's G17. I ordered a threaded gen 1-4 barrel for it to run suppressed since it has the taller sights.Also plan on running an optics. I shot a couple hundred rounds through it an no hiccups. The mag well is too shallow and you're limited to types of mags that'll work with it. I got a Mec gar mag and ground it down. Id been using that over the KCIs that come factory. Never trusted them in a defensive pistol. The finish on the frame easily wears off, but for the price you cant beat it. Shoots smooth and soft. The grouping i get from this isn't as tight as other clones, could be the barrel twist. other than that, there is no functional issues.

I have plenty of other pseudo-Glock pistols, but none with a metal frame. Especially one in its second iteration (Ultra) where you assume they've corrected any shortcomings from the first go-round. I like the feel in the hand, the feature-set, and that it still takes Glock magazines. I just wish the flared magwell was detachable because it will not work with the new metal 18 round mags from Mecgar. Most of all, a great price and quick shipment from KYGUNCO.
