Hello all, This will be my very first post on the Glocktalk forums, although I have been a "lurker" here for some time. My issue: For the last 2 months I have been attempting to hunt down a Glock 21 SF with ambidextrous magazine release and picatinny rail. I have been mostly unsuccessful at finding one. The ones that I do find are often from individual sellers who are not willing to ship out of state. And as my luck would have it, my local gun shop actually has one! But the poor thing is beat to hell. Go figure... So now I will enlist the help of the wonderful GT community in my search. If any of you know of, or currently have a 21 SF w/ ambi mag release and pic rail up for sale I would appreciate it if you would let me know! And before anyone mentions it. Yes, I am aware of the problems with the Gen 3 ambi magazine release. I tend to be the type to make small modifications/fixes to any issues with my guns, so I will likely be modifying the mag release to increase its durability/reliability. I plan to add a fluoropolymer coating of some sort to increase the wear/abrasion resistance of the polymer parts, making the mag release both smoother and more durable (less likely to stick). Hopefully it will work. If anyone knows of a different fix please post it here. One last thing, since the picatinny rail model is considered to be rare I am curious to know exactly how uncommon they really are. If anyone has information on approximately how many of these models were produced I would be interested in knowing. Thanks! -Will Wanna kill these ads? We can help!
