I have a Glock 22 gen 3 that is completely stock. I got to try the trigger on a Glock 35 recently, and I believe it would be a great improvement over the stock trigger on my G22. I was told this improved trigger is simply a swap of the disconnector and parts cost for this is under $30.00. Has anyone attempted this swap? Is it as straight forward as the gun shop guy says? I was checking out triggers at glocktriggers.com and they are about 150.00 to 170.00 for a whole unit. I would love hear from anybody with experience with the factory Glock 3.5lb unit or the glocktriggers.com unit especially with experience on the difficulty of doing the swaps on your own.
