I have owned the above Glock20 since 2004. I origionally bought it for hunting the NW Fla river swamps by foot and from a small boat. I also carry it during my scouting trips prior to deer season.
I outfitted my gun with Tru-Glo TFO sights which are both fiber optic lighted and trijicon lighted at night. GREAT SIGHTS !! I also added a extended slide stop and a "butt plug". I did a super $.25 trigger job and changed the connector to the 3.5# model.
I ordered a 6" OEM Glock "hunting barrel" from either Glockmeister or Lone Wolf,as I did most of my other parts. I polished the feed ramp,chamber,and bbl hood to a chrome like shine.
I also added a Viridian high power green laser to the gun. I can see this lasers dot in the bright sunlight at 50yds,but hunting the swamps or now the deer trails,my targets are very rarely in the sunlight. The laser can be selected to either pulse or constant on. The pulse mode is much quicker to ID when looking thru te brush.
I origionally set up to reload this chambering. But before I did I got an extremely good deal on Blazer 200gr ammo. Then gave the Double Tap 200gr WFNGC (hardcast) ammo a try. It shot great and killed deer and the larger hogs like a lightening strike. Both of the above ammo shoots to the same POI so I have a great training round.
My gun's trigger guard has been undercut so the middle finger can be positioned higher on the gun which puts the web of your hand higher for more control and recoil mitigation. This seems to allow me to control the weapon better for faster repeat shots. I hit a big sow some years ago on the third shot. She was on a full out run.
I have often thought about buying a Glock40 with RMR but at this point my older gun will take care of all my hunting needs. I have killed deer,hogs,and a couple unfortunate coyotes with my gun. Biggest deer . . 120lb 8pt. Biggest hog . . 255lb gnarly old boar that tried to cut me . . TWICE. ---- SAWMAN
