The new sider lock manual trigger has been a godsend for those of us who prefer IWB holsers, the trigger really works and is effective from standard and long slide glock pistols all the way down to sub compact models.
The included instructions were weak compared to the website instructions but once you follow the companies website instructions youll have the trigger ready to rock in 10 minutes flat.
Youll need a punch and some magnifier to see things but its really a breeze to drop the safety in.
The issue of manual safeties on a glock like my model 22 in 40 sw is apparently an issue of contention for some glock devotees.
All I can say about the sider lock is it saves my life every time its switched on.
