Primary Weapons Systems has released a replacement slide — the EDS or Enhanced Duty Slide — for Gens 1-3 GLOCK 17 and 19 pistols. Swapping this slide onto your gun is supposed to improve the trigger pull to a crisp, consistent, 4 lb. break. Sure enough, PWS’s factory-fresh demo GLOCK felt just like a normal GLOCK. Ten seconds later we’d swapped the slide and the trigger pull was excellent. I was shocked just how crisp it was with almost no creep at all and a very nice break. The slide also brings front cocking serrations, great looks, and DLC coating to the table. More details and photos follow. . .
