Double check on some of the Glock web sites for your G26, but many of the compact Glock models can exchange trigger parts with their full size counter parts. For instance, the compact G29 can use the smooth trigger from a G20. Just so you know, the full size Glock triggers are not flat, but smooth, curved ones. Still, I find them much easier on my index finger than the serated ones.
The only reason for the serated "target" triggers on the compact and sub-compact models is to help give the guns enough points to allow them to be imported into the USA. Silly gov't regulations.
