Tell the truth Reflex264 - why did you stop at 3 and not go for 5???

My son-in-law has the slim Glock 21 and put in different trigger springs and it now breaks around the 3.5 to 4 pound area and from a rest at 25 yards, it will do 2" with about any ammo you want to feed it. Of course, with a little less than perfect gun handling, we can open those groups up to about 4"s no problem.
