Who makes adjustable suppressor height sights?

You're right. There are a shot ton of triggers out there.

80% of them are marketed as 3lb triggers that get you down to 5-5.5lbs, the rest make a noteworthy improvement, but they don't change much but the poundage. I just finished a custom build on a G23 I have had for 20 years. One of the things I did was get a Ghost Evo 3.5lb connector, and it's ground so that the break is all the way back at the end of trigger travel. While the weight is a *lot* better than stock, it still has all of the negative attributes that go along with a Glock trigger-namely that it builds spring pressure, peaks, then falls off before the break actually comes. Really hard to be accurate like that for me because it feels like the trigger collapses in my grip before the break comes and I can't sit at the break point and be precise because it wants to finish releasing the striker. Not being able to be precise by pulling until the break point on my trigger travel is counter to everything I know as a shooter-Aftermarkey Glock triggers just trade off trigger weight for amplifying bad attributes of "Glock Perfection IMO.

Now, an M&P trigger is a different animal entirely. If you know what you are doing, a sear dropped in the gun and the stock parts massaged will get you a world class trigger with linear ramp-up of the pull weight, no stackup, short travel, with a short reset that is both tactile and audible. If you were to shoot my M&P's with ATEi trigger jobs in them, you'd agree-I'd put money on it.

The Glock I mentioned above? It hasn't been shot in .40 in almost 15 years because it KB'd-it's had a .22LR kit on it ever since. When I got it I was a new shooter and I didn't get "good with a handgun" until I started buying other guns a few years after the Kaboom. I thought I just sucked and that handguns weren't my thing. Then I got into M&P's, and suddenly I can shoot centerfire combat handguns like all the cool kids. 10 years worth of frustration at the range, and suddenly I can group 2" at 21 feet without breaking a sweat. I took my Glock out last night to the range so I could see how I liked it after all of the work was done, while the groups are better than I used to manage with the gun when it was stock, the groups were almost twice the size I can shoot my M&P at the same distance. Muzzle flip is a lot more pronounced too-can't wait to switch to the 9mm KKM barrel I have coming, .40 sucks for speed.

Sorry, don't know if it was a lemon or not but that thing was junk

My experience as well. Also, my mags wouldn't drop free and it had to have the extractor replaced twice

Any sights that fit the factory rear dovetail are adjustable for windage. Elevation is adjusted by using taller or shorter front or rear sights.
