I read a lot here on changes to Glock or to leave them stock, sounds like a lot of guys are really looking for a totally different platform but to each his own. I just picked up my second and probably last Glock, a G22 to go with my 27. As for changes I see XS Big Dots and .25ct trigger jobs. I want a smooth trigger pull but am leery of all the after market options for reduction. I like the simplicity and reliability of the Glocks and want to keep it that way. I may at some point shoot in local competition with my G22 for training exposure and I'm looking for input on sights and trigger changes for that purpose that stay close go OE.
