Well since I was ordering Glock parts last week courtesy of that Glock 21 I had the issues with, I also nabbed a competition trigger spring since a Glock 19 that I own has always had a horrible trigger.
I took this particular MPDC-marked Model 19 in trade from a DC cop that I know. He liked an Enfield that I had and I liked this department-marked Glock that he had, so we did a trade.
As I usually do with my Glocks, I swapped out the disconnector for a 3.5lb. disconnector offered by Lone Wolf. Usually that cleans muddy triggers right up, but in this case, it did nothing for the pistol and it still maintained a pretty crummy trigger pull. I tired of this pistol pretty quickly after that and relegated it to my wall rack with the other police-marked pistols that I own.
Well when I saw this spring at Glockmeister, I figured "why not?" and I ordered one. I just finished installing it in the Model 19, and WOW! The new trigger pull is crisp and clean and breaks like glass, although it still feels like about a 5lb. trigger, give or take, which really isn't bad for a carry gun. Now it's comparable to my 1911 and H&K P7M13, both of which break at 4.5lbs.
So naturally I had to run out and test-shoot it this morning. It was raining out, but hey--bad guys come out in the rain too, right? I loaded up the magazines and put a quick hundred rounds onto the steel targets, getting soaked but determining that it's functioning reliably AND shooting like a real sweet-heart now. For the first time since I acquired it, I really like this pistol and will consider carrying it. I'm still not a massive Glock fan but I trust the ones that I own to do their job when called upon and that's enough for me.
