Aluminum was chosen for our follower material after careful consideration, and experimentation, with other materials. It has some real advantages, but one of them is not that it will still look pristine after operating in a Kahr pistol for hundreds of rounds.
As shown in the photos, there are parts that can, and do, contact the followers that leave a mark with time. That is actually a good thing.
The plastic, factory followers can and sometimes do, break if the barrel contacts the follower after the last round is fired. That is one of the characteristics of the Kahr design that has been the case from the get go. Lakeline aluminum followers will not break, but they will get a ding in them if the barrel repeatedly hits them as both followers in the photo above demonstrate. That ding causes no issues with the follower, the functionality or the pistol. The followers get a similar type of look where they contact the slide stop, on the upper surface behind the area where the barrel contacts the follower in the photos above. Again, this is not an issue for functionality in any way.
If you are familiar with Lakeline products, you know we are not shy about using stainless steel. A stainless follower is cost competitive with the aluminum and its secondary anodizing. But, stainless is not a better choice.
One of our cardinal rules is our parts should not be able to damage the pistol. A stainless follower doesn’t get “dinged” up, but the barrel of the pistol does and that is not acceptable.
Aluminum is great in this application because it “gives” a little where needed to accommodate pistol to pistol variations without doing any harm to the pistol itself. Yet the aluminum is much stronger than plastic and doesn’t actually wear out. This “fitting” process is whole lot better than a broken follower or a damaged barrel with other materials.
