I will have to file this in the “it will never be tactical but will certainly be tacti-cool” category. XCaliber Firearms (and a few other companies including ATI) are now offering threaded barrels for your Glock 43 single-stack 9mm pistol.
One can see Phil’s thoughts on the Glock 43 here, but I am not sold on the idea. Having shot one myself, its not exactly a comfortable little thing and adding a suppressor to the front of one is not going to make the handgun any easier to use. I am not sure anyone offers suppressor-height sights for the handgun. At the least, you will need a pinky extension to keep the near mouse-gun stable in a normal-sized hand.
The new barrels are loaded with features. XCaliber proclaims they are “prevision machined and chambered” with a drop-in fit. Total overall length is 3.86 inches. Threads are guaranteed to be concentric (I hope so!) and include 1/2×28 UNEF Class 3A Threads (which is a good as one can get). Finally, the barrel is black Al Titanium Nitride Coated (AlTiN) for corrosion and erosion protection.
