+OEM Dagger fit; aftermarket Glock 19 barrels are not always Dagger-compatible
+1/2x28 thread pitch fits standard 9mm comps and suppressor pistons
+410 stainless with DLC finish
+Drop-in install on a Dagger Compact SW1 / SW2 slide
Cons
−Adds about 0.6 inches of muzzle length over the factory 3.9 inch barrel (the Full Size-S shares the Compact slide and barrel, so the same delta applies)
−Holster fitment changes; light-bearing holsters may need a longer profile
−Requires Dagger Full-Size or Compact slide; will NOT fit Dagger Micro
−Thread protector should be loctited or it can loosen under recoil
