just converted a perfectly good, but seldom used, Gen3 G23 (.40SW) to a faux G19 (9mm) with a Lone Wolf conversion barrel, 9mm ejector block, and 9mm extractor… did not include the longer 9mm extractor spring bearing… much more pleasant to shoot… may shoot Production this Sunday with it to give it a good test…my first handgun sport was IHMSA Metallic Silhouette with a 7TCU and Merril 30/30… I’ve wimped out in my older years, and even a .40 is not fun to shoot a match with anymore
