The 10 mm is my favorite handgun cartridge. Have a Glock 20 with both the 4.6 and 6 inch barrel. Also a Contender 10 inch bbl. Its versatility is what I appreciate most. Its ability to put a variety of bullet weights accurately over a wide velocity range will keep it from fading away. After it’s initial break-in and a little free tweaking by the Glock folks at Smyrna, GA, the Glock 20 has been super reliable for me for 12 years. It’s very suitable for either home defense or out in the woods (but not downtown in your pocket).
