Just got my first 10!

[jslj11244]

I just got my first Glock a mod 20. I bought  a 51/2 inch barrel and a 22 lb. spring. When I ordered my barrel I asked if I should use a buffer and they said not to. Just looking for opinions and also I noticed that there are no high cap. mags for the 10mm.
Will the high cap. mag for the 40 work. Am a new member here and looking to get educated on the glock 20. plan on using the 180 200 grain underwood and Buffalo Bore ammo.

jslj11244, Welcome to the forum!  Is your G-20 the 4th Generation?  No the 40S&W magazine will not accept the longer 10mm ammo.  sorry!
They make two magazine for the G-20  10 round +1 and  and 15 round +1  if you want more and your state allows they have extensions to allow even more rounds. and the Kriss extensions for the 45 are said to work for the 10mm...
