G19 MOS with Delta Point Pro. Owned it for 7 months and fired about 2,500 rounds. The 2 screws attaching the adaptor plate to the slide broke and the plate with the sight firmly attached flew off leaving the ends of the screws in the slide. The screws were the ones that come with the MOS Kit from Glock. I have only found one other similar failure reported on the internet. Called Glock and all they could offer was a replacement MOS Kit with the same screws which are quite small ( M3x6 - 6MM ). The slide is at a machine shop getting the screws drilled out - I hope. Anyone else had or heard of this problem?
