I was tinkering with the idea of trading for a gen 4 Glock 26 and was having a hard time coming up with info on some Crimson Trace grips for it. Do the LG-626's fit the gen 4's or could I be lucky enough to find a set that replaces the backstrap inserts like the M&P models do. If you have any info or pics that would be awesome. Any knowledge is appreciated. Thanks for looking and God Bless.
