I break mine down for inspection but don't clean after I pick up. Actually went from the shop to the range for both. I clean after first use, just me. I now have over a 1000 rounds each in both my late model Gen 4 G17 & 19 without issue. Great guns.
-Glocks: Gen 4 G17/G19/G41/G42; Gen 3 Zev Tech G17
-Sigs, HK, Walther, Springfield...etc, etc
