I bought one before the October North Shoot. I put 200 rounds through it and didn't have any issues. At the distance I was shooting the 230gr bullets were impacting a couple of inches high. I shot some 185gr Corbon +Ps and the POI was POA. It could have been that I'm not use to the white outline rear and dot front.

I just installed Ameriglo 3-dot night sights tonight and have a C-T.A.C. holster in route. The 6 round mags are a PITA since they don't last long during practice so I bought 4 used mags from CDNN.

I tried all kinds of ammo and even finished up my last box of crappy AMERC ammo without a hitch. I put 2 boxes of CCI Blazer through it. Blazer is apparently a Glock recommended brand.

I see your G36 has the newer extractor with the 'loaded chamber indicator' bump on it.
