See, thats where we seem to differ in opinion. I don't find factory triggers to be bad at all, and baring the occasional lemon, that goes for any of them.
I know we live in the wonderful age of marketing, and gunsmiths and gun writers, and everyone and their brother who seem to have just what you need, to let you enter the Matrix with a phone call or a buy now button, and buy your skills. No effort on your part is necessary.
Hey, if I, nobody special, can shoot box stock Glocks well, anybody can, if they are willing to make the effort. And the same effort, applies to any brand of gun you want to slip into that last sentence.
What I see over and over in threads like this is, people want someone, or something else to do all the work for them and/or make up for their shortcomings. That is human nature, and I get it, but it is what it is too. Insisting you can only shoot one type of gun, with this specific trigger, and those special grips screws, and that special Montana air in your ammo, etc, etc, just makes you a one gun limited specialist, and Im betting one that also way overestimates their skills even with that.
If you cant pick up a random gun off the counter and shoot it reasonably well from a cold start, that isn't the guns fault.
My realoads basically match any of the carry ammo I might use. 124 grain bullet at around 1150-1200 fps. 5.5 grains Unique (if and when you can find it these days, or BE-86 is what Ive been using for a while now. Ive used 4.5 grains of 231 in the past as well.
Stock 17 with a LWD threaded barrel and one of the above loads. Doesnt matter which, they all shoot the same. Those were shot "static" from SUL presentations at 10 yards.
An old box stock Gen 2 17 shot the day I got it. I hadn't take the laser off yet, nor did I use it as the batteries were dead. Shot a bit more "energetically" too, probably from 15 yards or so and in.
Even the "fat babys" shoot well, especially when you let them run.
Everything seems to like those loads too.
Thats the attitude.
