You the man and the resident glock expert.
@BrunotheBoxer Glock triggers out of the box can be hit or miss although I had a real good one in the 34 and a 43. I bought a 19 last year that was real heavy. A $20 connector and spring and a little massaging resolved that issue. I like five pounds. If you want lighter it will require some aftermarket parts
I would like to get her down to about 4 pounds or ever so slightly less.
