I just spent about 20 minutes trying to install the Hogue Handall on my Glock 27. I tried the hairdryer/heat method and then the detergent soap method. I gave up when my anger exceeded my good judgment, and before I tore the grip. A word of advice, a word of experience would go a long way here. When I've mastered the installation on my Glock 23, then I'll go to my Glock 27.
