Finished a little horse trading with an old time gun buddy and he threw in a NIB 3rd generation Model 26 Glock to sweeten the pot. First one I ever owned and never fired a round through one. A friend told me to shoot 19 mags in it with grip extensions and it might fit my hand better. Would like to hear from members who have used this configuration previously. Is it a satisfactory way for me to achieve a better fit for my hand ? Are some extensions better than others ? I’m a single action guy and this is unplowed ground for me. Many thanks in advance.
