as i posted before, i was having fte probs with my 36. i replaced the ex. and have since put 400 rds thru it with no problems. not sure if that was the fix or it simply needed shooting. i've over 1000 rds thru it now and the fte's seemed to be lessening as time went by. break in maybe. some here say no break in needed for a glock. bs. it's mechanical. it has tolerances. you get one part machined on the high, mating part on the low, you have a chance for a problem. hence break in. that's 400 rds of carry ammo also. GD. some shoot 200 rds of practice ammo and 20 rds of carry ammo and declare it carry worthy. again, bs. 500 of carry ammo is the minimum for me. just my opinion. anyway, i'm happy, as it's the favorite of my three glocks. 30 and a recently purchased 26, both with 700+ flawless rds. sorry for the long post. btw, same grip i've used for the last 30 yrs for all the limp wrist solutions i got earlier.
