I have been getting pretty used to the gritty and grippy texture of the new 4th generation of Glock pistols.
Neither my Gen 3 G23 or my Gen 1 G17 have this sort of texture so I thought WWH45D — what would Hickok45 do — and he’s a huge fan of Talon Grips, which he says, at least in sandpaper, help out with his accuracy and handling, so I ordered a couple sets and they were a snap to install.
Pretty much just use an alcohol wipe to remove any oil, schmutz, or dirt, and then you remove the sticker backing, place it according to the instructions, make sure the three front strap pieces go under the left side panel, and the just blast it with a very hot hair drier until everything shrinks-to-fit.
Err on the side of more heat and also make sure you press everything down and make sure there are no gaps or bubbles. And squeeze and press. Doesn’t it look great!
I installed it myself so it really must not be very tough and each grip was cut perfectly for the pistol I ordered it for.
