This may move into the other forum, but I just got my DGR and 22# spring today and installation was a breeze, very easy and I actually think that the look of the gun has improved (yeah, yeah, maybe a stupid thing but I like a good looking gun

)
I'll be taking it to the range tomorrow to try it out, and I'll have the original spring assembly just in case something happens/I don't like the combo I just installed.
Also, a big +++ to pistol-gear.com, they shipped the order out the day I ordered it and it arrived 2 business days later. Very nice!!
And, being a sucker for accessories, I bought the Packy grip thingy (is that technical enough for the part?) and will report on it as well after trying it {fwiw, I put the grip on over the decal grip i bought before, the combination of the two makes the grip feel very secure - I was worried about the grip slipping / turning }
