American National Firearms extended slide lock for all Glock models (except 36, 42 and 43.) A small part that makes a BIG difference, these parts are machined from stainless steel, not stamped, so they are perfectly flat. Your Glock is already perfect, everyone knows that, but you will be amazed at how much easier it is to remove your slide after installing this part. Serrated edges give you a great grip, but will not interfere with your holster. Our slide stop installs easily in just a few minutes and fits the hole in your frame better than the original, eliminating slop and improving lock up consistency. It is perfect in every way.
